It's a common situation where a powerful wired internet connection reaches an apartment, but the WiFi signal from the provider's equipment doesn't reach a remote room or office. In such cases, it's often necessary to use a second router not as a standalone access point, but as a signal receiver. This allows you to "catch" the wireless network in one part of the room and transmit a stable wired connection to a computer, Smart TV, or gaming console in another.
The implementation of such a scheme is possible thanks to a function that may be called differently on different devices: Client Mode, Bridge Mode, or WDS. The main task In this scenario, the router ignores the incoming WAN cable and searches for a network connection exclusively via radio. This turns the device into a universal adapter, extending the boundaries of your local network without running additional meters of twisted pair cable throughout your entire apartment.
The advantage of this approach is the ability to use old, but powerful routers that are lying around unused. Instead of throwing out the equipment, you get a fully functional Ethernet switch with WiFi receiverHowever, the setup process requires careful attention, as firmware interfaces vary significantly across manufacturers, and incorrect configuration can lead to IP address conflicts and complete network inaccessibility.
Operating principle and required modes
In order for the router to receive internet over the air and distribute it via cable, its operating logic must be changed. In standard mode, the device waits for a signal from the provider on the WAN (Internet) port and then distributes it. In our case, the WAN port often becomes inactive or repurposed, and the main source of traffic becomes WiFi module, operating in receive mode.
There are several technologies that can implement this scheme. The most common one is Client Mode (Client). In this mode, the router connects to another WiFi network like a regular device (like a laptop or phone) and broadcasts the received internet to its LAN ports. Computers connected via cable receive IP addresses from the main router, being on the same subnet.
Another option is the regime WDS Bridge (Wireless Distribution System). It allows you to connect multiple networks into one while preserving client MAC addresses. This is a more complex protocol, often requiring both routers (the main and client) to be of the same brand or support the WDS standard. For simple internet forwarding tasks on a PC, Client mode is usually sufficient.
⚠️ Attention: Switching to client or bridge mode changes the device's functionality. Parental controls, torrent downloaders, and USB modules are often disabled in this mode, as the router ceases to be a full-fledged gateway and becomes a transparent bridge.
It's important to understand the difference between Repeater and Client modes. A Repeater receives a signal and distributes it further via WiFi, creating a single network with the same name. Client mode, which is discussed in this article, receives a signal via WiFi but distributes it primarily via LAN ports, although WiFi on the client device itself can also be activated for distribution.
Preparing equipment and resetting settings
Before performing any manipulation of network equipment, it's crucial to properly prepare it. This will avoid address conflicts and ensure you can access the device's settings after changing its operating mode. First, make sure you have access to the main router (the internet source) and know the password for its WiFi network.
It's best to reset the second router, which will act as a receiver, to factory settings first. This will eliminate any possible configuration errors from previous use. To do this, locate the button on the router's body. Reset (often recessed into the case), press it with a paper clip and hold for about 10-15 seconds until the indicators blink simultaneously.
☑️ Preparing to set up the bridge
After the reset, connect your computer to any LAN port of the router you're configuring using a cable. Don't connect the WAN cable from your ISP or the main router yet. Access the web interface using the address on the sticker at the bottom (usually 192.168.0.1 or 192.168.1.1). If the address of the main router matches the address of the one being configured, a conflict will occur, so the addressing will need to be changed.
Setting up an IP address and local network
One of the most common problems when creating a network from two routers is IP address conflicts. If the main router distributes addresses in the range 192.168.1.x and has the address itself 192.168.1.1, then the second router cannot have the same address. You need to change the IP address of the second device so that it is in the same subnet, but not the same as the main one.
Go to the LAN settings section (often called Local area network, LAN Setup or Network). Find the IP Address field. If the address of the main router 192.168.0.1, then ask the second one, for example, 192.168.0.250This will make the addressing unique and allow you to always access this device's settings in the future, knowing its static address.
| Parameter | Main router (Source) | Second router (Receiver) | Comment |
|---|---|---|---|
| IP address | 192.168.0.1 | 192.168.0.250 | The addresses must be in the same subnet. |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | Must match everywhere |
| DHCP Server | On | Disabled (in bridge mode) | Only one person should distribute addresses. |
| WiFi Channel | Auto or fixed | Coincides with the main one | For WDS stability |
After changing the IP address, the router will prompt you to reboot. The computer should also be switched to obtain an IP automatically so that it re-requests an address from the main router (if DHCP is already enabled on the main router) or reconnects to the device's new address. Now the second router's interface will be accessed via the new address, for example, 192.168.0.250.
WiFi reception mode configuration (Client Mode)
The most crucial step is finding and activating the desired operating mode. In the router interface, look for sections with the following names: Opening hours, Operation Mode, Administration or System toolsIn modern firmware TP-Link, Asus, Keenetic or MikroTik This item is often placed on the main screen or in the quick setup wizard.
Select mode Client (Client) or Client BridgeIn some models it may be called Wireless BridgeAfter selecting the mode, the device will likely require a reboot. After enabling, the interface may change, and some options specific to router mode may disappear.
Next, you need to find the main router's network. Go to the wireless networks section (Wireless -> Site Survey or Search for networks). The device will scan the air and display a list of available WiFi networks. Find your primary network in the list, select it, and press the button. Connect or Join.
In the window that opens, you will need to enter the password for the main router's WiFi network. Make sure the encryption type (usually WPA2-PSK) matches the signal source settings. If everything is done correctly, the WiFi indicator on the second router should light up or change its blinking pattern, indicating a successful connection.
What to do if the network is not found?
If the network search list is empty, make sure the main router is broadcasting Wi-Fi. Also, check if MAC address filtering is enabled on the main router. In rare cases, manually entering the SSID (network name) and channel in the client settings may help if automatic search fails due to standard incompatibility (for example, mixing 2.4 GHz and 5 GHz).
Disabling the DHCP server on the client
A critical point that beginners often forget: In bridge or client mode, the second router should not distribute IP addresses to connected devices. This feature (DHCP Server) should only be performed by the main router. If DHCP remains enabled on both devices, the network will become chaotic: computers will receive incorrect gateway addresses and will be unable to access the internet.
Find the section in the menu DHCP or Local area networkThere will be an option there. Enable DHCP serverIt is necessary. turn off (Disable). Save the settings. After this, all devices connected via cable to the second router's LAN ports will receive IP addresses directly from the main router, effectively "behind it."
There is an exception: some routers in "Client" mode automatically disable DHCP and reconfigure ports themselves. However, in "WDS Bridge" or "Repeater" mode, manual control is often required. Testing is simple: connect your laptop to the second router and check the connection status. If you receive an address like this: 192.168.x.x (where x is the subnet of the main router) and there is Internet access - everything is configured correctly.
⚠️ Attention: After disabling the DHCP server, you may lose access to the second router's web interface if your computer has a static IP address. Ensure that "Obtain an IP address automatically" is set on your PC's network card, or temporarily manually assign a static address in the same subnet to complete the setup.
Setting up a WDS wireless bridge
If simple client mode is unavailable or two networks need to be connected while maintaining broadcast domains, WDS technology is used. It allows connecting routers from different manufacturers, although stability is higher when using the same hardware. Unlike client mode, WDS often requires manual channel configuration.
On the main router, you need to fix the WiFi channel (for example, channel 6) by disabling "Auto" selection. Then, in the main router's WDS settings, add the MAC address of the second router. The same procedure is performed on the second device: fix the channel and enter the MAC address of the main router in the WDS list.
Key security parameters must be identical: encryption type (AES/TKIP) and password. WDS is sensitive to mismatched settings. If one router is configured to WPA2-Personal, and the second one on WPA/WPA2 Mixed, the bridge may not rise or operate unstably.
After setting up WDS, the wireless indicators on both routers should show an active connection. A speed test in this mode can show a throughput drop of up to 50%, as the radio channel operates in half-duplex mode, receiving and transmitting data alternately.
Diagnostics and possible problems
Even with proper setup, problems can arise. If you still can't connect via cable, first check the connection status in the second router's web interface. It should say "Connected" next to your WiFi network name. If the status is "Disconnected," check the password and encryption type.
A common problem is a "loop" or incorrect gateway. Make sure the computer connected to the second router has the main router's address, not the second router's, set as the Default Gateway. If the gateway points to the second router, it means DHCP isn't disabled or isn't working correctly.
It's also worth paying attention to the frequency bands. If the main router only broadcasts 5 GHz and the second one only supports 2.4 GHz, connecting them in client/WDS mode won't work unless the second router is dual-band but configured incorrectly. Make sure you're trying to connect devices on the same frequency band.
Frequently Asked Questions (FAQ)
Is it possible to connect routers from different manufacturers (for example, TP-Link and Asus)?
In Client Mode, yes, it's a standard protocol, and brands don't matter. In WDS Bridge mode, compatibility isn't guaranteed and depends on each manufacturer's specific protocol implementation. It's best to use Client Mode.
Will WiFi work on the second router after setup?
Yes, in most modern models, when Client mode is enabled, the WiFi module doesn't turn off, but instead begins distributing the internet received over the air. However, the speed may be lower, as the radio airwaves are congested with both receiving and transmitting data.
Why is the speed via cable through a second router lower than directly?
Speed loss is inevitable with a wireless connection (called "air bridging"). The radio channel divides bandwidth between receiving data from the main router and transmitting it to your computer. Interference and distance also play a role.
Is a cable required between routers to set up client mode?
For the initial setup, yes, a cable is required between the PC and the router being configured. For the overall setup, a cable between the routers is NOT required, as the connection is via WiFi. The cable is used only to connect end devices (PC, TV) to the second router.
