It often happens that in the apartment and in the country, one router is not able to confidently cover the entire territory. The issue becomes even more relevant in private firms, where an office, a store and a warehouse are located in the same building, and wireless Internet is needed throughout the company. It will help to unite Wi-Fi routers into a single network with a single Internet access on one of them.
How to connect and integrate routers into a common network
There are several of them - different methods for cable and Wi-Fi. The latter method is the most popular and has varieties: bridge mode, repeater mode, client mode (as a simple Wi-Fi module) without distribution (distribution only via LAN cables), etc.
Some step-by-step instructions have been translated into Russian.
Creating a bridge based on WDS
WDS technology allows you to deploy local area networks of any coverage area without a LAN cable, consisting exclusively of Wi-Fi routers. Such a device simultaneously receives data and distributes it further to other routers. You can create a wireless line or “tree” from routers of any length, which allows you to enter the settings of any of the previous routers through connecting to any of the following.
As an example, TP-Link routers. This is one of the most popular brands. D-Link routers and distribution points are found in almost every second user.
Free data exchange between routers and network clients
For example, the TP-Link 11n device takes the IP address 192.168.1.1, and the access point (Root AP) - 192.168.1.2. Each device in the wireless network is assigned its own address - otherwise there will be a conflict of IP addresses, the connection will be lost. IP is changed by going into the settings of the router and entering the desired IP address.
Change IP on the router
Follow these steps to change the IP address.
- From any browser, go to 192.168.0.1 or tplinkwifi.net. If there is no connection with the local network of the router, the TP-Link dummy page will be displayed.
- Enter the word “admin” for the username and password. Upon successful login to tplinkwifi.net or via local IP, the router will ask for a username and password
- Give the command "Network - Local Area Network". Go to LAN settings
- Specify the desired IP value, click the "Save" button. Enter the desired address and click save
Connected devices must be reconnected again. Connection settings on the PC or gadget from which the IP changed on the router also need to be changed.
Setting up a WDS network on a TP-Link router
Depending on the firmware version of the router, the options and lists in the settings are in different order. The functionality remains the same, without considering the innovations when updating the device firmware or replacing it with another model.
- Go to the main page of the TP-Link device in a familiar way.
- Give the command "Wireless Network" - "Wireless Settings". Recommended Wi-Fi Settings on TP-Link Routers
- Check the WDS option. Without it, creating a Wi-Fi radio bridge is impossible. Turn on WDS for Wi-Fi bridged network
- Select the channel number between the paired devices. Choice of channel number, technology and connection speed
- Click the device search button (Search). After scanning the Wi-Fi radio range, select the second router by SS> Find the SSID from the second router and connect to it
- After selecting the second router in the list of the first (which you are setting up now) on the previous page SS> Protection recommended
- Give the command “DHCP - DHCP Settings”, select “Disable DHCP Server” and click on “Save”. DHCP (auto selection of available IP from the range of available IP addresses) can delay the network connection for a long time. Automatic IP selection (DHCP) often makes it difficult to connect
- To restart TP-Link, give the command “System Tools - Restart” and click the “Restart” button. Click Reboot to restart
WDS Network Bridge Creation Complete! To check the network, do the following.
- Run the command line (in Windows XP / Vista / 7 give the command “Start - All Programs - Accessories - Command Line”, in Windows 8 / 8.1 / 10 use the search bar in the “Start” menu and start the CMD application (English “command. exe "). Run the command line under the administrator account
- Ping your connection to the Root Access Point (root router) by issuing the ping 192.168.1.2 command. If the instructions are followed to the smallest detail - the network bridge should work
You can use your network bridge. Routers of other manufacturers are configured in the same way - they all support WDS, and the menus and submenus in the settings are not much different.
How to connect an access point to a router
In the 2000s mostly Wi-Fi routers that work only in the hotspot mode (access points) were produced. In recent years, hundreds of models have been released that combine all the modes - in fact, these are universal Wi-Fi network devices.
Any router is put into access point mode. If you do not intend to connect a powerful hotspot, designed for hundreds of subscribers and serving a whole village or holiday village, to your wired line, then the role of such an access point is played by the usual model that distributes the Internet to 8-12 devices, which has three antennas and works with any neighbor porch, in a dormitory or in an office "high-rise building".
Connecting the AP to the router is much easier to do exactly by cable. The operation of modern devices in TD mode is also possible - when using hybrid bridge mode in Wi-Fi.
TD connection to each other without wires
Due to the increased popularity of the WDS Bridge and Repeater modes, implemented purely via Wi-Fi, conventional access points continued to be replaced by routers until the hybrid access point mode was implemented in the first ones.
To take advantage of the Wi-Fi connection of an AP without using a cable, the wireless setting must be different from the wired one. As an example, we took two identical ASUS WL-500gP V2 routers.
It is very different from connecting routers via LAN cable.
- Connect to the first AP via IP 192.168.1.1 from any PC or gadget, log in to enter the AP settings by entering the admin name and password. Enter the name and password to enter the router settings
- Give the command "Wireless Networks - Interface". The AP settings for connecting to another AP begin with them.
- Assign the AP name, for example, WL550gE. Set the value of WEP encryption to zero (WPA2 is best for protection). Set Wi-Fi network name and AP encryption
- Give the command “IP Configuration - WAN / LAN”. AP needs to assign addresses
- Enter the IP address - 192.168.1.1 and click the "Apply" button. Check subnet mask: 255.255.255.0
- Give the command "Wireless Networks - Bridge Mode". You must configure the bridge mode to connect to another AP
- For Access Point Mode, select Hybrid Mode. Press the “Continue” button to proceed to the setup of the communication channel between the APs
- Force the Wi-Fi channel number. Both APs must operate on the same channel.
- Turn on the option “Connect to APs from the list of remote bridges”.
- Allow the connection of anonymous devices to your AP (the last setting in the list). This is necessary so that the connection to another AP works correctly
- Write down the MAC address of the second AP and click on the “Add” button. This is the second device to which the first will connect.
- Click on the “Finish” button. Click Setup Complete
- Click on "Save and restart." Click the button to write the settings to the router and restart it
Configure a second access point
The second AP is configured similarly to the first AP. Menu navigation is the same. Do the following.
- Write SS> It should be different from the address in the first AP
- Give the command “IP Configuration - DHCP Server”. Go to the DHCP server settings
- Disable the DHCP server function. DHCP server will slow down the connection, disconnect it
- Go to the bridge mode settings submenu and write down the MAC address of the first AP (in this example, it is 00: 0E: A6: A1: 3F: 87). Check if the AP is using the same channel (here it is the 3rd).
- Save the settings and restart the AP by running the familiar command.
You can try these steps with ZyXEL, TP-Link and other brands. Moving through the menu in the settings will be different, and the instructions will be similar. To connect two access points, routers must support hybrid bridging, forced Wi-Fi channel selection, manual MAC entry and DHCP management. Classic TDs cannot connect with each other - they only support the distribution of the network from the cable. Using the same router model as a bridge connection in the TD mode will speed up the setup - the menu for all devices in this bundle is the same.
Communication between routers by cable
A LAN cable is needed only at guarded facilities (hospitals or polyclinics, military factories, special services, banks, research institutes, etc.) - Wi-Fi networks are prohibited under their regulations. A serious organization uses wired routers, server stations, and LAN-hub devices, rather than routers and access points. In other cases, the use of Wi-Fi networks together with cable lines will suit you.
There are two schemes of local networks: cascading (can be used as part of a tree) and a network with equivalent devices.
Cascade Router Network
The scheme is as follows: each next router is connected via a WAN socket to the LAN socket of each previous one. This is necessary to facilitate the configuration of the Internet, which is on the main router. Setting up such a “router” network does not pose any difficulties.
Each WAN of the next is in the LAN of the previous
So you can build a network of routers with a tree topology of any length. This is a kind of pyramid of devices. From any subsequent one, you can go into the settings of any previous one that lies in this pyramid. Each previous one will be the main one for those standing directly behind it. On any of them, the Internet will work from the "top" main router. However, viewing the settings of subsequent routers in this chain from the previous one will not be easy - to do this, use the network mode without WAN.
- Enable DHCP on the main router and delimit the pool of IP addresses. For example, on devices of the D-Link DIR line, the setting is available by the command “Settings - Network settings”. The first router is ready to distribute IP and routing network and Internet
- Enable IP auto-receive on the secondary router. So, on TP-Link this is called by the “Network - WAN” command. This will allow the second router to receive resources from the network of the first and Internet traffic
Do not forget to configure Wi-Fi security on each device. After saving the settings and restarting the routers, the network will work.
Equivalent communication between routers
In this case, the connection between the routers through the LAN is used. This is like a peer-to-peer network. The main condition in such a network is IP settings from the same subnet.
For example, the TP-Link models, previously configured for a multi-valued network, are taken. Do the following.
- Disconnect the cable between the first (which was previously the main one) and the second (before that it was secondary) routers.
- Connect to the first router via Wi-Fi and disable DHCP in its settings. Give the command: DHCP Settings - Disable - Save
- Go to the familiar LAN submenu and check if the IP of the main gateway has changed (for example, it is 192.168.1.1).
- Specify in the settings of the second device an address different from that indicated on the first (for example, 192.168.1.254, 192.168.2.1 or some other) - this will prevent a conflict of IP addresses on the local network. Give the command: Network - LAN, enter the desired IP and press the save button
- Make sure that the settings on both routers are saved, plug both ends of the cable into the LAN jacks of the routers.
How to fully configure one router through another
So, you connected the routers to each other and set up the network. The last task is to make sure that the settings of any of the routers are accessible through any other on your network. As an example - the same network of two TP-Link routers with an equivalent (not cascading!) Scheme. For different brands and models, the menu may differ, but many actions are already familiar to you. Do the following.
- Connect to the Wi-Fi network of the first router from a PC, tablet or smartphone.
- Enter its main (gateway IP, for example, the same 192.168.1.1). Its page with the main menu will open.
- Now enter the IP address of the second device in the address bar of the browser (let it be 192.168.0.1) - its settings will open.
- Try changing something in the settings, for example, change the gateway address (from 192.168.0.1 to 192.168.0.123).
- After saving the settings, enter in the address bar of your browser a new IP (in this example, 192.168.0.123) of the second router that you specified in its settings - the settings menu for this router will reappear.
- Change the network name of the second router (you are connected to the second router through the first): give the command “Wireless Network - Basic Settings” and enter a different Wi-Fi network name. When searching for your Wi-Fi SS networks> Go to Wi-Fi settings and change the SSID broadcast for other devices
- Change the Wi-Fi security settings on the first router you are connected to. To do this, go to the "Security" submenu and select the desired mode. Naturally, your PC or gadget will shut down. Change WPA2 Mode and Encryption Algorithm
- Reconnect to the first router and enter its IP in the browser (here it is 192.168.1.1) - you will get back to its settings.
- Connect via Wi-Fi to the second router, go to the IP of the first (as before, it is 192.168.1.1). Repeat the settings performed on the second router.
Attention! If you try to change the IP settings of the main gateway, DHCP server and others responsible for the LAN / WAN, the connection between the routers will be broken! Do not change these settings.
Pairing a Router with Routers and Access Points
The router can be the main router - modern routers contain up to 5 LAN sockets and, as a rule, one WAN socket, into which a 100-megabit line from the provider's optical terminal enters. You can use a classic router (without Wi-Fi distribution) - these are in the computer classes of schools and universities or in the server rooms of enterprises and institutions. Each LAN line of the router has a router or access point that distributes Internet and local network resources via Wi-Fi and / or other LAN cables.
This network is based on a tree structure that is already familiar to you from the settings of the main routers in networks that unite the same routers. The router is configured in the same way - use the instructions above.
Using industrial and home-made pointed antennas (frequency 2.4 / 5.5 GHz) it is interesting to organize access to the Internet, say, in a holiday village overlooking the "high-rise buildings" of the nearest city, without having to drag the fiber from the nearest communication center. In general, there is a limitless field for experimentation.
Both on routers and on a PC, setting up subsequent devices is to enter IP addresses manually or assign them to automatically receive from a previous device, based on the network topology.
The terminal devices can be either routers or computers
A PC network card with two LAN ports works like a simple router.
Configure a router with other devices
For example, we take a TP-Link router with an access point - a regular router with several LAN outputs, one WAN input and a Wi-Fi access point that is temporarily disabled to simplify setup. There is a tariff with a speed of 100 Mbit / s, without the “Static IP” service.
- Make sure you have internet access without a router.
- Turn off the power on the router, then on the optical / ADSL modem and on the PC.
- Connect the modem cable to the WAN input on the router, and the LAN input on the PC to one of the router's LAN outputs.
- Turn on the power of the devices in the same sequence.
- From any browser, go to the address 192.168.1.1 and log in.
- Give the command "Network - WAN". Assign IP Auto Receive
- In the line of the WAN connection type, select dynamic IP, click the "Save" button (it will appear if the router receives a response from the modem).
- Wait a few minutes and check the WAN status on the Status page. IP addresses are registered, there is an Internet connection
- If the router is assigned a real IP, then the connection to the modem works. If the IP addresses of the router and the modem match, change the IP of the router, for example, to 192.168.2.1. To do this, go to the familiar LAN settings page.
- Restart all devices in the same order.
Everything! The network works, the Internet is. The settings of routers without Wi-Fi, with dozens of LAN outputs and multiple WAN inputs, are similar.
Features of the DHCP server
Usually, or rather almost always, the built-in DHCP server is turned on by default. It distributes addresses belonging to a certain range, for example, 192.168.1.50-199. Please note that IP addresses are always available that belong to the local network, but are not distributed by the DHCP server (we have 192.168.1.1-49, 200-255). One of these values must be assigned to the second router. That is, his address will no longer end with a unit.
LAN scheme - all addresses are unique
If everything said is clear to you, we recommend that you first set up the first, that is, the main router. Performing this action, you should go to the tab that is responsible for LAN settings (we need the DHCP server settings).
Самое главное – ничего на данной странице не менять. Для наших целей будет достаточно, если Вы запишите стартовое и конечное значение на листик.
Теперь перейдём к настройке второго роутера, который подключать к первому пока что не надо.
Выключаем DHCP, меняем IP-адрес
Итак, суть действий, производимых над «роутером 2», понятна из названия главы. Выполнять их нужно именно в указанном порядке (так будет проще). Зайдите в web-интерфейс и найдите вкладку, содержащую параметры DHCP. Напомним, что здесь мы говорим о втором роутере.
Отключаем лишний сервер DHCP
Избавившись от DHCP, как показано на рисунке, выполните сохранение настроек. You will see that nothing bad happened - the web-interface still opens.
What to do next, we must consider in detail.
Change IP, open the interface
In our case, it was possible to correct the value of the IP address assigned to the second device on a tab called “LAN”.
Assign a new IP address
We came up with a new value, guided by this: if we have a range of 0.1-0.100 busy, then why not use a sequence ending in 0.200. The address “192.168.0.200” belongs to the subnet of the first router, and at the same time it is outside the range of its DHCP server. Be aware that by saving your changes, you may lose contact with Router 2.
So, after changing the IP, you noticed that you can no longer access the web interface. Then there are two solutions to the problem:
- You can leave everything as it is, turn off the second router and connect it to the first (according to our scheme). You will enter the interface of “router 2” in a couple of minutes using the address that was invented by you.
- If you urgently need to open the interface without connecting two routers, do this: configure the PC network card to a static address. You need to use a mask with the last zero, and the IP value must belong to the corresponding subnet.
Network Card Setup
Note: “static” should be used only temporarily, and then, when the entire network is assembled, return the settings to “auto DNS” and “auto IP”. In general, our scheme is designed to ensure that when both routers are connected to each other, all devices receive IP and DNS in automatic mode. The interface of the first of the two routers will be available at the standard address, the second at the address that you set. Have a good routing!
Additional configuration of “router 2”
The WAN port that is not involved in our scheme also needs to be configured. On some interfaces, you can disable the WAN port (use this).
If such an option is not provided, simply configure the IPoE connection in the second router, that is, the DHCP client. So the minimum amount of resources will be occupied.
In the scheme that we considered, the first device acts as a router, which means that it is in it that you need to configure static routes.
Or, instead, they use the UPnP protocol. In the interface of the second device, it is easy to understand that you need to disable both of these options - so there will definitely be no problems.
A similar scheme should be used if it comes to setting up IPTV. But the “Multicast Rate” parameter in the second access point should not be zero, otherwise there will be no IPTV in such a wireless network.
In conclusion, note this. Advanced Wi-Fi settings may not include a setting such as Multicast Rate. But this will mean that multicast packets get into the Wi-Fi network without hindrance.
First LAN Router - Second LAN Router
This connection scheme of two routers is the simplest. This is how it will look in practice:
That is, you connect the LAN port of the main device that distributes the Internet and the LAN port of the second one used to expand the network. In this case, the second router will act as a regular switch or access point, without any routing functions. To configure a second router through a router in cascade, you first need to do the following operations on it:
1. Disable DHCP server
This is done in order to eliminate the likelihood of a conflict between devices, since the first distributing router already has a server turned on and it will assign addresses to clients. Why do we need two of these?
2. Change the IP address of the second router
Almost the vast majority of network equipment manufacturers by default set the IP address 192.168.1.1 for the local network on the router. Accordingly, if you want to connect and configure a router through a router, and at the same time they will have the same addresses, then nothing will work due to a network conflict. Therefore, it is best to configure the second router at the end of the first subnet. That is, if the distributing router has the address 192.168.1.1, then the second one has 192.168.1.254.
Thus, both devices will be visible on the network and available for management.
First LAN Router - Second WAN Router
This is the second option, with which you can connect the router through the router in a cascade with a cable.
Unlike the previous method, there will be not one large local area network, but two - each router has its own. Note: With this connection of devices from the main router, the internal network of the secondary will be unavailable, but from the second the LAN will be at a glance. This must be taken into account.
The configuration features of this scheme imply that you don’t need to touch anything on the main distributor either. On the second router, you need to go into the connection settings and set the type to "Dynamic IP (DHCP)".
I also strongly advise you to change the IP address of the second router on the local network if it matches the first. Otherwise, the connected router may malfunction due to the coincidence of the subnet on the external and internal interfaces.
How to connect two routers via WiFi
In addition to the cable connection, you can configure the router-router network via a wireless WiFi network. True, there is one condition - the connected access point must have a WDS function or repeater (repeater) mode. In this scheme, the second router is placed approximately on the verge of the coverage area of the first and expands its network due to its own transmitter.
Everything is configured elementary. To configure a router through a router, we don’t touch anything on the first one, and on the second you need to enable WDS mode:
Next, you must either manually specify the network to which you will connect, or find it using the search. After that, both of these devices will be combined into one single grid with a single SSID.
Comment: In WDS repeater mode, the second router only works to expand the wireless network. When you connect a computer or laptop via the Internet cable to them will not be heard.
