Dir 300 setup as a repeater. Setting up a WiFi repeater (repeater) for a wireless network. WDS technology. Enabling client mode in standard firmware

Repeater WISP (Repeater Wireless Internet Service Provider) - for organizing shared access of office and home computers to the Internet, both via the Ethernet port and via wireless WiFi. I show the example of the DIR-300 NRU B5 model, firmware version: 1.2.94 - 1.4.3.

Firmware version: 1.2.94

Reset to factory settings.

Firmware version: 1.2.94. If you have the new firmware - 1.3.3, then you can return to version 1.2.94 by first flashing version DIR_300NRUB5-1.2.93.fwz, and then immediately, without rebooting the router - DIR_300NRUB5-1.2.94.bin ( Firmware on ftp.dlink.ru).

• We enter 192.168.0.1 in the address bar of the browser and log into the router using the login "admin" and password "admin". Go to the menu "network" - "connections" - "LAN". There we change the IP address to another subnet - from 192.168.0.1 to 192.168.1.1 and do not forget to save all changes during any operations.
• In the same place, in “connections”, go to “WAN” and change the connection type to “IPoE”, the physical interface to “WiFiClient”, IP and DNS to “automatic” (you may need to enter your settings, as if you were setting up a wired WAN- compound). Then “edit” and “save”.
• In the "Wi-Fi" menu, enable the wireless connection.

• In the "Wi-Fi" menu, go to the "client" and turn it on. After automatic search networks will be listed available networks. “Click” on the network you need (in my case, it’s DIR-620); if the network you need is not found, change the position of the antenna and repeat the “search for networks.” We remember the channel on which the network sits. Then “edit” and “save”.
• In the “basic settings” of the Wi-Fi menu, we manually set the channel of our selected network. We save everything.
• We check “Network statistics” in “Statuses”. Everything should be “connected”, if not, save and reboot the system.
• The next time you enter the router menu, do not forget to enter the address 192.168.1.1.

Firmware version: 1.3.3

For this firmware, all settings and changes are made in the same way, so I won’t repeat it, just don’t forget to connect the “client” to “wi-fi” first, otherwise the “WiFiClient_1” settings will be hidden.
Everything works for me, I was glad to help.

Firmware version: 1.4.0 - 1.4.9

And for this firmware, all settings and changes are made similarly to the previous ones, PrtScn pictures are shown below. In order for the WiFiClient settings to appear in the "Network >> WAN" submenu, you must first go to the "Wi-Fi >> Client" section, then select the network and save it.

A simple reflector for a router antenna

• It takes 5 minutes to make from a regular beer-juice can (see photo below).
• If the signal is caught with the router's vertical antenna, you can use an existing hole in the can.
• We put the structure on the antenna and align it so that the distance from the antenna to the reflector is approximately 15-20mm.
• We are looking for the rotation angle for maximum signal reception. To do this, click on “search for network” in the “wi-fi client” after each change in the direction of the reflector (at least 2-3 times in one position if the signal was weak).
• If you want to catch a reflected signal (the signal source is not in line of sight), then remember physics from the 5th grade - the angle of incidence is equal to the angle of reflection and install the reflector accordingly.
• I advise you to manipulate not only the reflector, but also the position of the antenna - for me, maximum signal reception was achieved in the lying position of the router antenna, and even at an angle of 45 degrees to the window. In a vertical or other position of the antenna, the network I needed was not caught at all, even with a reflector.
• As a result, I achieved such movements on my router, increasing the weak reflected wi-fi signal from 15% (without a reflector) to a stable 39%, and the number of caught networks increased from 8 to 19 pieces.
• In the second photo, a test design of a directional antenna is screwed to the reflector for additional passive amplification of the wi-fi signal (I saw something similar on the Internet and decided to check how much more the signal would be amplified). On the “knee” in 15 minutes I wound transverse ~5 cm elements from the same wire, only without the sheath, onto a guide made of copper wire in a PVC sheath, at a distance of ~3cm from each other - more accurate dimensions are available on the Internet.
  In your case, to improve the signal, such an antenna can be located both vertically and horizontally - it is located experimentally, regardless of how the router antenna itself will be located.
  As a result, another 5-7 new wi-fi signal sources were added and the power of the network I needed rose to 44% and even resonated up to 55-60% a couple of times.

Sometimes it becomes necessary to configure two routers together: to increase the coverage area, to connect more than 4 devices via cable. Basic settings on the second router. For example, I took the D-Link DIR-300. Typically the chain looks like this:

The difference is in how the devices are connected to each other. I considered 4 schemes:

1. The first router starts the Internet, the second is configured as a receiver, a client - a “repeater”, “repeater”. Bridge - bridge mode, receives and distributes the Internet via cable.
2. Similar to the first option, but distributes the Internet via Wi-Fi.
3. The second router also receives the signal, but not via cable, but via Wi-Fi. WDS technology - wireless bridge. Then it distributes it via cable.
4. Similar to the third option, but distributes via Wi-Fi.

There is no separate “Repeater” or “Repeater” mode in D-Link routers. He showed how you can set up their analogy using improvised means. But NAT is running on each of them, which causes difficulties when forwarding ports and setting up IP cameras.

In all schemes I use two routers. The first is DIR-615, the second is DIR-300. It doesn’t matter which router you have first, the main thing is that it starts and distributes the Internet. Usually, this is already configured and works automatically. All configuration details are related to the second router. They were described in the article.

Preparing for setup

First you need to go to the web interface of the router. Open your browser and enter in the address bar 192.168.0.1 . An authorization window will appear. In the login field enter admin, password - admin, standard data. If it gives an error and you don’t know your login and password - .

This will reset not only your login information, but also all existing settings.

If you can’t log in, there is a separate one that should help.

When using two routers together, check the gateway address for each, it should be different.

Often they coincide. The DIR-300, like most D-Link routers, has standard addresses 192.168.0.1. If the first one is the same, then it needs to be changed in the DIR-300 settings so that there is no conflict between them. Go to “Network” – “LAN”. In the IP address field, replace 0 with 1, you get 192.168.1.1. In the DHCP server it is the same - “Start IP” is at 192.168.1.2, “End IP” is at 192.168.1.100. Click Apply.

Click on the red number at the top, then on “Save and Reload”. Wait 95 seconds.

Keep in mind that after this, to log into DIR-300, you need to enter 192.168.1.1, not 192.168.0.1, in the browser.

"Repeater" via cable

The first router launches the Internet depending on the provider - PPPoE, 2LTP, Dynamic IP. Afterwards, the second router - DIR-300, receives the signal via cable and distributes the Internet to other devices in two ways: via cable and via Wi-Fi. Let's consider both options.

By cable

Internet cable to the WAN port of the first router. Then, from its LAN port, a network cable is connected to the WAN port of the DIR-300. From its LAN port a cable is connected to any device: computer, laptop, all-in-one.

I already wrote above that it is important that router gateways differ from each other. Connect the devices according to the diagram.

1. provider network cable;
2. patch cord - connects both routers;
3. patch cord - connects the second DIR-300 router to the computer.

If the router with factory settings is new or reset, then the “Dynamic IP” connection type was initially selected for it; there is no need to change anything. Immediately after connecting your computer or laptop, the Internet should work.

If the browser gives an error, check what type of connection is selected on the router. Go to “Network” – “WAN”. There is probably nothing there or an incorrect connection or multiple connections have been established. Check the boxes and click “Delete”.

Then “Add”, select the connection type “Dynamic IP”, click “Apply”. Save your settings.

Via Wi-Fi

Internet cable to the WAN port of the first router. Then, from its LAN port, a network cable is connected to the WAN port of the DIR-300. Then it distributes the Internet via Wi-Fi to any device: laptop, tablet, smartphone.

The algorithm is similar to connecting via cable from the DIR-300 to a computer, but in addition you need to configure Wi-Fi on it. Go to “Wi-Fi” – “Basic Settings”. The “Enable wireless connection” checkbox should be checked. In the field opposite “SSID”, come up with and enter a name for Wi-Fi. Click Apply.

Go to "Security Settings". In the “Network Authentication” field, select “WPA2-PSK”; in the “PSK Encryption Key” field, create and enter a password for Wi-Fi. Click Apply. Save your settings.

After, for example, on your phone, open the list of available networks, select the name that you came up with. Enter your password and click “Connect”.

"Repeater" via Wi-Fi

Just as with the cable repeater scheme, the first router launches the Internet. Then the DIR-300 receives the signal, but not via wire, but via Wi-Fi. Afterwards, it distributes the Internet to other devices in two ways: via cable and via Wi-Fi.

By cable

Internet cable to the WAN port of the first router. Then the DIR-300 is connected to the first router via Wi-Fi in “client” mode. From the LAN port of DIR-300, a network cable to any device: computer, laptop, all-in-one.

In the menu on the left, click on “Wi-Fi” – “Client”. Next to “Enable”, check the box.

If you need the DIR-300 to distribute Wi-Fi, check the box next to “Broadcast wireless network”.

Then select the wireless network of the first router and click on it. In the “PSK encryption key” field, enter the Wi-Fi password of the first router. Click Apply.

Save your settings. The indicator on the name of the network you are connected to will turn green.

Go to “Network” – “WAN”. Check the connection box, click “Delete”, then “Add”, described in more detail above. Select “Dynamic IP”, in the field opposite “Interface” set “WiFiClient”, click “Apply”.

Then save the settings.

Via Wi-Fi

Internet cable to the WAN port of the first router. Then the DIR-300 is connected to the first router via Wi-Fi in “client” mode. Then it distributes the Internet via Wi-Fi to any device: laptop, tablet, smartphone.

The method is similar to the previous one, described above. Except for one parameter - check the box next to “Broadcast wireless network”. Although I tried without it, both routers distribute Wi-Fi. But put it in any case, it won’t hurt.

There are 2 options for choosing the network name and password for Wi-Fi on the DIR-300 - the second router:

1. the name and password for Wi-Fi are completely the same as the first router;
2. different from him.

In the first case, if your device is a smartphone, the laptop is already connected to the first router, it will automatically connect to the second. Afterwards, it will independently reconnect to the router with the best signal level.

In the second case, you need to disconnect from the first router and connect to the second - select the network, enter the key. The advantage is that you will be able to see which device you are connected to in this moment. Useful for diagnosis.

Otherwise, there is not much difference; to set up Wi-Fi, go to “Wi-Fi” - “Basic settings”. In the field opposite “SSID”, enter a name and click “Apply”. Then go to “Wi-Fi” – “Security Settings”, enter the password in the field opposite “PSK encryption key”. Click Apply. Save your settings.

Connect your devices, it should work.

1. Briefly described how to go into the router settings and what to change for correct collaboration.
2. I disassembled 4 diagrams for connecting two routers. Different modes of the second router using the DIR-300 as an example: as a receiver, client, Wi-Fi client - “repeater”, “repeater”. Technologies WDS (wireless bridge), bridge (bridge).

If something is unclear, write below in the comments, we will try to understand your situation and find a solution.

D-LINK network equipment is well known both in Russia and abroad. In a wide range of devices, a wireless router stands apart entry level- D-LINK DIR-300. Thanks to the low price, excellent reliability and good technical specifications it became the first truly affordable home Wi-Fi router. The model turned out to be so successful that it is still in production. What are the differences between routers of different years of manufacture, how to connect and configure them for maximum efficient work- the topic of our article.

Router appearance, technical specifications

D-LINK DIR-300 - entry-level router (router), designed for use at home or small office. It allows you to connect clients to the Internet both via cable (twisted pair) and using a wireless connection (WiFi). Using a cable connection, you can connect four computers, and via Wi-Fi - any number of clients. However, with each client connected via Wi-Fi, the access speed will drop. If one client can operate at a speed of 150 Mbit/s, two are already at a speed of 75 Mbit/s, and so on.

The router has been on the market for more than ten years, during which time three generations (revisions) of this router have been released.

DIR-300 revision A

The oldest router in the line, it has long been discontinued, although it can also be purchased on the secondary market. The b/g wireless module provides speeds of up to 54 Mbps in ideal conditions.

DIR-300A is a veteran in the line of routers

The router's Ethernet ports allow you to organize a local network with access speeds of up to 100 Mbit/s. But the Internet speed for clients local network will be almost half as low: small volume random access memory and a weak processor allow the DIR-300 rev. A process Internet traffic at a speed of no higher than 50 Mbit/s. If you are connected to the Internet with a faster data plan, it is worth replacing your old router with a more powerful one.

The proprietary gray-orange interface is the calling card of early models of D-LINK routers

DIR-300NRU revisions B1, B3, B5

The abbreviation NRU in the model name means that wireless module complies with the N standard and can provide theoretical Wi-Fi speeds of up to 150 Mbps. The prefix RU indicates that the model was developed and produced for the market of the former CIS countries.

DIR-300NRU B1 - strict appearance and 150 Mbit/s over the air

Dual core processor with clock frequency 350 MHz and 32 megabytes of RAM allow you to install alternative firmware on these routers, such as OpenWRT and DD-WRT, which significantly expands the capabilities of the router and improves the stability of its operation. The processor speed is sufficient to work with tariff plans up to 100 Mbit/s.

OpenWRT - software for routers with great capabilities

DIR-300NRU revisions B7, D1, A1

These types of router are built on a new hardware platform, so alternative firmware will not work on them. But the standard software was also significantly redesigned: the familiar web interface was replaced with a new one, with an interactive client connection map and the ability to change many settings without rebooting the router.

New D-LINK software saves the user from manipulating alternative firmware

Models B7 and D1 are available in a vertical design, and the revision A model will probably be remembered for its appearance in the shape of a black cylinder.

DIR-300NRU A1 - space design and completely earthly characteristics

DLINK DIR-300A was the first wireless router I purchased almost 10 years ago. Simple and unpretentious, it worked without turning off for almost 5 long years, without failures and without freezes, and only connecting to another, faster Internet provider made me replace my old friend with a new router. But thanks to the DD-WRT firmware, the veteran is still in service, working as a repeater wireless network in a country house. Low speed has become the trump card of this router - it hardly heats up, which means it can work stably in difficult climatic conditions, for example, in hot summers.

Preparing the router for operation

In order for the D-LINK DIR-300 to connect all your devices with a single home network and provide each client with access to the Internet, it is necessary to carry out a number of preparatory measures. The router must be connected by cables to the provider's network and home computers, and the clients' network cards must be configured to automatically obtain addresses. After this, you can configure Internet access and create a wireless network.

Connecting the router, preparing for setup

The router connection diagram is simple: the provider cable is plugged into the Internet socket, local network computers are connected to the network connectors LAN1-LAN4. Smartphones, tablets and others wireless devices connected using a Wi-Fi network.

Creation home network based on DIR-300NRU

Configuring a computer's network card to work with a router

The DHCP server is automatically activated in the router out of the box - the router itself will issue network addresses to connected computers. Therefore, before you start setting up the router, it would be useful to make sure that network adapter computer or laptop is configured to automatically obtain a network address.

1. Right-click the “Start” button and select “Network Connections” from the user menu.

   Call network connections from the user menu

2. In the network connections window, select the desired adapter and use the right mouse button to open its properties.

   The network adapter properties contain TCP/IP protocol settings

3. From the list of protocols, select TCP/IP settings and open them for editing.

   TCP/IP protocol is the main conductor of a wireless network

4. Configure to automatically obtain the network address and DNS server address, as shown in the screenshot, and then click OK.

   Automatic receipt of addresses is set

Modem web interface, configuration and access protection

The modem's web interface, through which most of its settings are performed, is located at 192.168.1.1. The username is admin, and the default password is blank, meaning you do not need to enter it. Change your access password immediately after initial setup modem This will protect your network from third-party interference.

1. Switch to advanced settings mode.

   Quick settings and connection status on home page modem

2. In the “System” section, follow the “Administrator Password” link.

   Access to system parameters hidden in advanced settings

3. Enter your password and click the Apply button.

   Enter your password and confirmation in the field below

Internet provider connection settings

The router's web interface allows you to configure your Internet connection both semi-automatically (using the setup wizard) and completely manually. Before starting setup, make sure your Internet connection is activated by your service provider. To do this, try connecting to the Internet without a router by connecting the ISP cable to your computer's network card.

Fast Internet Connection Wizard

For the technically untrained user, D-LINK has implemented the Click’nConnect tool in the router software, which requires the user to go through just three screens of simple settings with a choice of connection type and authorization parameters. The router will determine the remaining connection options automatically, provided that the Internet provider cable is already connected.

1. Open the web interface by entering the address 192.168.1.1 in the Internet browser.
2. In the “Network” section, follow the Click’nConnect link.

   All step-by-step “wizards” are launched from the quick settings page

3. Check whether the provider's cable is connected to the WAN port of the router.

   Make sure the ISP cable is connected to the WAN port

4. Select from the list the type of connection that your Internet provider uses, for example, PPPoE.

   Select Internet connection protocol

5. Enter the authorization parameters from the agreement: login, password and VPN server name (if an L2TP or PPTP connection is used). In order to access additional settings, move the switch in the lower left corner of the window to the “Details” position.

   Enter the login and password from your agreement with the provider

6. Check the settings in the system report window and if there are no errors, click the “Save” button.

   Check that the settings are correct and click the “Save” button

If you are used to “keeping your finger on the pulse” and want to make settings manually, this can be done by switching to the advanced settings mode.

Through the advanced settings menu, the connection to the Internet provider is configured

L2TP setup

L2TP is one of the types of VPN in which a “tunnel” can be established not only using the TCP/IP protocol, but also protocols more low level: ATM, X.25 and Frame Relay. The protocol provides encrypted traffic, so L2TP connections are used more often in corporate networks than for connecting individuals to the Internet.

1. Manual configuration of connections occurs from the advanced settings menu

2. Create a new Internet connection

3. Enter the parameters in the window that opens account: login, password and VPN server address.

4. For a static connection, enter the IP addresses assigned by your ISP

5. Click the "Apply" button.
6. Returning to the window with the list of connections, activate the created entry as the default connection.

   Make the created entry active by default

Setting up PPPoE

Connection via the PPPoE protocol is the most common among Internet providers, and it is easier to configure than others, since the only authorization parameters required are a login and password.

1. From the advanced settings menu, follow the WAN link in the Network section.

   To connect using the PPPoE protocol, follow the WAN link from the advanced settings menu

2. In the list that appears network interfaces click the "Add" button to create a new connection.

   Create a new connection using the "Add" button

3. Enter the account parameters in the window that opens: connection type (PPPoE), login and password.

   Set the connection type to PPPoE, and take the connection login and password from the agreement with the provider

4. If a digital TV set-top box or smart TV is connected to the router, set the IGMP checkbox to the enabled position.

   Activate options for IPTV viewing. Don't forget to assign one of the LAN ports to connect a TV set-top box

5. Click the "Apply" button.
6. Returning to the window with the list of connections, activate the created entry as the default connection.

Setting up PPTP

Setting up a connection using the PPTP protocol is no different from setting up L2TP, discussed earlier. Similarly, two types of connections are supported: with static and dynamic addresses. To authorize, all you need is your login, password and VPN server name. Please note that this type connection creates a large load on the router's processor. If your tariff plan provides a connection speed of 90 Mbit/s and higher - you should think about buying a new, more productive router.

1. From the advanced settings menu, follow the WAN link in the Network section.

   Manual configuration of the PPTP connection occurs from the advanced settings menu

2. In the list of network interfaces that appears, click the “Add” button to create a new connection.

   Create a new connection for PPTP access

3. Enter your account parameters in the window that opens: login, password and VPN server address. If the symbolic server address is not provided by your ISP, enter it in TCP/IP address format.
4. If the secondary connection is a static rather than dynamic IP, provide the DNS server addresses, network address, netmask, and gateway address.

   For a static PPTP connection, enter the IP addresses assigned by your ISP

5. Click the "Apply" button.
6. Returning to the connection list window, activate the created entry as the default connection.

Setting up a static IP

If you connect to the Internet with a static IP address, a login and password are not required. In the parameters of the created connection, you enter the address received from the provider, the subnet mask and the gateway address, after which the router is ready for use.

Home network and wireless settings

After the router's connection to the Internet is configured, all that remains is to configure the wireless network and the connection of wired clients, thereby completing the creation of a home network. Never create a wireless network without password protection, even if you have MAC address binding enabled. An attacker can easily clone the MAC address and connect to your network.

Configuring Wi-Fi (creating an access point, changing the password)

The second step after setting up a connection to the provider will be to turn on and configure the wireless access point, which will allow you to distribute the Internet to devices with a WIFI module: laptop, tablet, smartphone.

1. It is better to configure the wireless network from the advanced settings menu

2. Click the "Advanced Settings" button.
3. Make sure the wireless connection slider is in the green (on) position.

   Make sure WI-FI mode is turned on

4. Open basic wireless settings. Here, set the name of the wireless network, broadcast channel, and the name of the guest network. Clients on the guest network will receive internet, but will not be able to connect to the local network.

   Enter the network name and select the broadcast channel

5. Return to the main screen and open your wireless security settings. In them, set the encryption type and WIFI access password.

   Create and enter a wireless network access password

6. Returning to the main screen, click on the save settings link in the upper right corner.

The password set for the wireless network is used by the router to encrypt transmitted data. The more characters in the password, the more secure the encryption, but the load on the router’s processor is also higher. The optimal key size is 8–13 characters.

Port forwarding (port mapping)

Some users need to access resources on their local network from the Internet. Access to home network folders, picture from home IP camera, remote administration programs Remote Administrator or Team Viewer and dozens more required applications. To organize the possibility of such access, so-called port forwarding is required, that is, the router connects an external network port and an internal port. Setting up port forwarding is easy using the modem's web interface functions.

1. Open an Internet browser and go to the router's web interface at 192.168.1.1.

   Add a new rule

2. In the window with a list of reassigned ports, click the “Add” button.
3. In the port settings dialog, fill in the following fields sequentially:
   
4. Click the "Apply" button in the lower right corner of the screen.

Setting up IPTV (digital TV)

Setting up IPTV allows you to select one of four network ports for transmitting a digital video stream to it. You can connect a network media player, Smart-TV or digital television set-top box to this port.

A few months ago, family friends asked for help in connecting SmartTV to their home router - DLINK DIR-300. Connected using the “IPTV Setup Wizard”, the TV perfectly showed one and a half hundred digital channels, but none of the Internet services worked: youtube, mail, online cinema, even the weather forecast complained about the lack of Internet connection and did not start. Studying the documentation suggested that in order to simultaneously transmit video streams and Internet traffic to the port, it is necessary to configure a Dual Access connection, but the existing router software did not allow this, and the owners did not want to flash the router with alternative firmware so as not to lose the warranty. And yet, a solution was found: we connected a Wi-Fi adapter to one of the TV’s USB ports and configured a connection to the router’s wireless network through it. And through the Ethernet connection there was a digital video stream. The price of the issue is about 500 rubles, and a new router with Dual Access support would cost much more.

LAN and DHCP server settings

The router's advanced settings mode allows you to configure the parameters of the dhcp server, local network and internal interface of the router.

Switching D-Link DIR-300 to repeater (repeater) mode

The standard software does not support switching the router to repeater (repeater) mode. If you bought a new, more powerful router, and want to use the old DIR-300 to expand your wireless coverage area, you can try installing the alternative DD-WRT firmware, in which the repeater mode is configured in just a few mouse clicks.

1. Using the internal software recovery (update) function, install the DD-WRT firmware.
2. Disable the WAN interface and the DHCP server on the Installation tab (General Settings section). Enter the network settings data for the repeater. The device must be on the same network as the main router. We will have a network 192.168.128.0/255.255.255.0, in which the gateway is a machine with the address 192.168.128.5. She is also DNS server. For the future Dir-300 repeater, the free address 192.168.128.2 was selected, which is not distributed by the DHCP server.

   Enter the network address, subnet mask and gateway information

3. Specify the wireless network type as “Repeater-Bridge”, and the wireless network name must be entered identical to the network name on the main router. In this case, this is the DizAr_net network. Save the settings again.

   Firmware status page - repeater mode activated

Unfortunately, the DD-WRT firmware does not support the entire line of DLINK DIR-300 models. On the project website you can download update images for revision A1 (the oldest DIR-300) and for version DIR-300NRU revisions B1-B3.

Video: installing DD-WRT firmware on D-LINK DIR-300

Administration of D-Link DIR-300

A router is a stand-alone device that can work for weeks without user intervention. If problems do arise, then you cannot do without the manipulations of the network administrator. You may need to reboot the router or reset it to factory settings, and in severe cases, even update the firmware.

Resetting the router to factory settings

Resetting the router to factory settings may be necessary if the device does not work correctly and access to the web interface is impossible. Fortunately, all D-LINK DIR-300 routers have the ability to perform a hardware reset to factory settings.

Updating internal software (firmware)

Updating the internal software will help eliminate errors, increase performance and improve the stability of the router.

1. Check the revision of your router; this information is on a sticker located on the bottom cover of the device.

   

   The manufacturer's website contains firmware files for all revisions of the router

2. From the router's advanced settings screen, select the Software Update link under the System section.
3. Use the “Browse” button to specify the path to the firmware file and click the “Update” button.

   Specify the path to the firmware file and begin the update process

4. The router will begin the update procedure, which will take about 10 minutes.

Be extremely careful when choosing the firmware file. Software from a router of a different revision or even more old version When installed, the software may render your device completely inoperable. It can only be restored at a service center.

Reboot the router

The easiest way to reboot the router is by turning off the power and unplugging its AC adapter from the outlet. If the router is installed in an inaccessible location, you can also reboot it through the web interface.

Step-by-step instructions on how to do it setting up DIR-300. It starts with connecting the router.

Physical connection

• Plug D-link DIR-300 into a power outlet via the power supply.
• Install the cable from the Internet provider into the appropriate port of the router.
• Connect the computer and router with a wire (patch cord, i.e. blue cable).
• For Wi-Fi, screw on the antenna.

In the end, the wires on the back of the router should look something like this:

On a desktop computer connected via a wire, open Control Panel through Start, go to Network and Internet, then Network and Sharing Center and shared access, then go to Change adapter settings. See if your local network is turned on. Enable if it is disabled.




From now on, for the network to work, you don’t need to configure anything else on your computer. If you experience any problems, you may not have the driver installed. network card(or for Wi-Fi), refer to our article on.

How to log in to the admin panel

You no longer need to configure the computer itself; the router stores all Internet settings within itself. But to set up the network you need to visit the router through the web interface. This can only be done via a wire, so you will have to log in either through a desktop PC with a wired connection, or connect a laptop/netbook via a LAN network to the router.

• Most often, the bottom of the DIR-300 contains the address of the local “site” with settings, as well as a login and password. Typically the address is 192.168.0.1.




• Enter it into your browser and you will go to the page generated by the router.




• The default login and password is admin.




Settings

Primary setup and path to basic Internet settings:

• You can immediately change the interface language.




• And set a password for the DIR-300 router. If you forget it, you will have to reset it, along with all settings, to “default”.




• To configure the Internet, go to the Advanced settings item below.




• In the Network block, follow the WAN link.




• Create a new connection; to do this, click the Add button in the lower right corner.




Basic network settings in the D-link DIR-300 router:



• Here you need to select the type of Internet connection. Usually this is PPPoE.
• You may have to clone the MAC address of your computer's network card into the router using the green arrow button (not always necessary, only if your ISP has a MAC address binding).
• Enter your Username and Password. This is the Internet access data from your provider (if you don’t know, look for it in your agreement with the provider).
• In other fields, you can leave everything as default and click the Save button.



• You will then be redirected to the previous page. The new connection you configured appears there. Check to see if the round check mark for this connection is set to Default Gateway.




• As a result, the Internet on a computer connected via LAN (i.e. by wire) should work. To check, go to any site:




• To prevent the settings from being reset, click Save on the router:




Congratulations, you have configured the Internet in the router and connected your computer to it via LAN.

Enabling WI-FI and setting up

To work via WiFi, you need not only a laptop with a wireless network adapter, but also setting up a link router. You already know how to log into the router through a computer, do it.

• In Advanced Settings, find the WiFi section. Check that the green switch is in the on position. Just below, follow the link to Basic Settings.




• Check the Enable wireless connection checkbox and enter the name of the network. It will display like Wi-Fi name, which is visible to all devices (even those not yours) within the router’s coverage area.




• Click change.



• We will be brought back, click Security Settings.



• Write down a password for Wi-Fi, otherwise anyone who catches it will be able to use it.




• Save changes to Wi-Fi settings on the DIR-300 router.




How to connect to Wi-Fi

If you configured the D-link router via a laptop/netbook using a wired connection, then you no longer need it. Disconnect the wire physically, and in Windows turn off “Local Area Connection”.

• Now turn on Wireless network connection(it must be present if all drivers and software are available on Wi-Fi).



• A window will appear in the tray next to the clock with the found WiFi networks. Remember what you called it in the router settings. Select and click Connect.



• Enter the password you set during setup Wi-Fi router D-link DIR-300.




How to forward ports on a router

What is port forwarding? This is the port binding on external interface DIR-300 router with a device port on the local network. The idea is to give access to the device from the Internet using a specific open port router.

In practice it might look like this. There is a need to provide access to remote control slave. desktop PC connected to the Internet via the DIR-300 router (or another reason). To do this, create a redirection rule WAN port to the home PC port.

To do this, go to the Advanced section, then to the Port Forwarding setting.
How to set up:




• Select a name for the rule (to avoid confusion, it is better to give meaningful names).
• Select specific number public port or specify a range of ports). Public is an external port for the Internet. To register only one specific number, indicate it in the form of a starting and ending number.
• In the test example, we opened port 3389.
• Enter the IP address of the PC (server) to which the ports are forwarded. It is worth reserving this IP address for a specific computer in the DHCP reservation settings on the router, then it will not change over time. If you don’t want to make backups in the router, you can enter the IP address manually in the settings of the PC’s network card.
• The test example specified the internal gray IP address 192.168.1.100.
• Register the port for receiving incoming connections on a PC on the local network.
• For the test, we specified the default port 3389.
• Don't forget to check the box on the left to enable the rule.

Setting up IPTV

Setting up IPTV on routers: D-Link DIR-300, DIR-400, DIR-615 and DIR-655. Log in to the admin panel (instructions at the beginning of the article), you will see the main settings menu. Click Advanced, then Advanced Network. Specify the parameters:

• Check Enable Multicast Stream so that IPTV works via cable.
• Check the box for Wireless Enhance Mode to operate IPTV over Wi-Fi.
• We save with the “Save Settings” button (at the top of the page).

Perhaps the interface in your model will differ slightly from the picture shown.




If the specified menu items are not in the router, it may need to be flashed new firmware supporting IGMP proxy or Multicast Routing. Also note that the interface shown here is English, yours may be Russian.

How to turn on the router as a repeater

In order for the DIR-300 to work as a repeater, it needs to be flashed with the DD-WRT program.

• Version A1 is flashed via TFTP (so it is more difficult to make a repeater out of it).
• Version B1 can be flashed via the web interface.

Let's start setting up the repeater:

• We change the DIR-300 subnet to another one so that it differs from the main source point (for example, a laptop). If the laptop has 192.168.1.1, then here you need to make 192.168.2.1.
• Available enabling DHCP, to do this, select the IP of the main point (192.168.1.1) as the gateway.
• In point WAN settings go to Automatic-configuration DHCP and activate STP. Save.



Wi-Fi setup:

• In Wireless, select Mode – Repeater (or Repeater Bridge, if you have a different firmware version).
• The other remaining settings must match the source parameters (SSID, channel, connection type).
• The channel must be set to specific, not Auto. Security settings should also be similar to the source settings.
• Save.




After saving the settings, go to Status > Wireless > Site Survey, select the source point. Click the Connect button and save again. As a result, your router should receive the source IP and operate as a repeater.

Video settings on Rostelecom

Step-by-step video instructions for setting up D-Link DIR-300 for Rostelecom:

How to reset and reboot

To reset the settings to factory defaults, the router must be plugged in. After that, click the Reset button. It is recessed into the body to prevent accidental pressing, so you will need a toothpick. In some models, to reset you need to press Reset and hold for 15 seconds.




This will reset absolutely all settings, including the password (by default, like the login, it is admin).

How to reboot your router:

• Log in through the web interface and click Reboot.




• The router will reboot in 30-60 seconds, during which time you will be shown a message stating that it cannot be disconnected from the power supply.




• After this, the D-link DIR-300 is completely ready to work with the old settings.

Also, to reboot the router, you can physically disconnect it from the power outlet (preferably for 15-30 seconds).

Conclusion

You have learned how to configure the D-link DIR 300 router. And remember, the main ways to fix some problems with the router are to reboot and flash the firmware. Even if you have the most latest version firmware, then re-flashing can get rid of network glitches that have appeared (similarly).

The article describes a way to expand the coverage area of ​​a wireless Wi-Fi network based on Asus and D-link equipment, home or small office class. For example, Asus WL-320gE, Asus WL-520gU and D-Link DIR-300. Often in a room (office, apartment with many concrete walls, two-story rooms) the signal from 1 router is not strong enough to reliably cover the entire workspace. The way out of the situation is to become installing a repeater (repeater or amplifier) ​​Wi-Fi signal.

One solution to the problem is to install separate routers (access points) in adjacent rooms with different networks. In this situation, different parts of the network can access the Internet quickly, but cannot communicate with each other. For this option, in principle, it is possible, but for an office it is categorically unacceptable.

So, we need a stable Wi-Fi network throughout the office. For this we need to have two devices − WiFi router And WiFi access point with repeater function.

Wireless Distribution System (WDS) technology

Allows expand your wireless network coverage by combining multiple WiFi points access to single network without the need for a wired connection between them (which is mandatory in a traditional network design). You can use the creation virtual Wi-Fi access points, .

Negative sides WDS :

• Network throughput drops up to 50% compared to a normal connection.
• The speed of work via WiFi decreases because one channel is used to connect points
• compatibility problem between different manufacturers
• WEP encryption only.

Positive sides WDS :

• lack of wired connection between Wi-Fi access points
• saving MAC addresses of network clients

WDS operates based on MAC addresses, similar to a network switch. URE- this is a signal repeater, the signal is relayed without processing, like a wire repeater - by a hub, when the received packet is simply repeated to all ports, or with an antenna crab.

Setting up the Asus Wl-520gU router

For example, the Asus WL-520gU router is connected to a wired Internet provider and will act as a gateway for other computers on the network. Address Asus router WL-520gU on local network 192.168.1.1. It will also act as a DHCP server on the local network. But the main thing is that in the same network the router and access point should not simultaneously be DHCP servers.

Setting up D-link DIR-300 in Wi-Fi repeater mode

At d-link settings dir-300 as a Wi-Fi signal repeater, the settings of the second access point remain unchanged. It is recommended before setting up.

Alternative firmware D-link DIR-300

DIR-300 with factory firmware does not have Wi-Fi signal relay mode. Search official firmware D-Link with repeater support is useless. Therefore, let's pay attention to the project DD-WRT firmware at www.dd-wrt.com.

DD-WRT- This free firmware for wireless routers , built on BroadCom, Atheros, Xscale, PowerPC chips. Initially developed for the Linksys WRT54G series of routers (including WRT54GL and WRT54GS) and is a miniature operating system, based on the Linux kernel. Distributed under the GNU GPL v2 license.

First you need reflash DIR-300 with DD-WRT firmware. There are descriptions of various firmware methods of this router. DIR-300 Revision B1 can be flashed directly from the standard administrative web interface. If you have any problems with the firmware, you can try reset the router from crash mode.

Setting up D-link DIR-300 in repeater mode

After successful firmware, proceed to setting up the router in Wi-Fi repeater mode. During the first connection to the reflashed DIR-300 via IP address 192.168.1.1, you will be asked to set a new username and password for subsequent configuration.

Instructions for installing DIR-300 in Wi-Fi repeater mode

Installation - Basic Settings

• disable the WAN interface
• DHCP server
• we register network settings to our repeater. It must be on the same network as the main router. For example, there is a network 192.168.1.0/255.255.255.0, the gateway and DNS server is a router with the IP address 192.168.1.1. For the Dir-300 repeater, we knock out a free static address, for example 192.168.100.1, which is not within the distribution range of the DHCP server.
• Save the settings.

Wi-Fi setup

• Wireless network type - Repeater-bridge,
• set the SSID name to the same as that of the relayed network
• Save the settings.

Setting up a secure network with WEP encryption

• Wi-Fi Network Security
• register a similar encryption algorithm and network key that is used in the expandable network!
• Save.

As a result we have configured repeater Wi-Fi networks based on DIR-300. If you have any questions or would like to contact the contact number of an ITcom specialist.
