A situation where the internet cable does not reach the required room, but the wireless signal Wi-Fi Many users are familiar with the problem of barely detectable or completely missing signal there. Walls, ceilings, and even household appliances can become a serious obstacle to radio waves, turning high-speed internet into a slow and unstable connection. In such cases, purchasing additional expensive mesh systems or powerful repeaters is not always possible or desirable.
An excellent and often free solution is to use an old but working router as a receiver (client) of the main signal. Instead of gathering dust in a closet, the second device can receive internet over the air from the main router and distribute it further via a cable or create a new access point. This allows you to significantly expand your network coverage without running meters of Ethernet cable throughout your entire apartment.
However, the process of converting a router into a receiver has its own technical nuances and depends on the hardware model. Not all devices support the required operating modes, such as WDS, Client Bridge or RepeaterIn this article, we'll take a detailed look at how to check compatibility, what settings need to be changed, and how to avoid common configuration errors to ensure your network functions seamlessly.
Checking Receiver Mode Support and Preparing Equipment
Before setting up, you need to make sure your potential receiver is capable of operating in client mode. Manufacturers often hide this feature deep in the menu or don't implement it at all in budget models. First, you need to know the exact device model and its hardware revision, as firmware for different versions can vary significantly.
There are several standards for implementing signal reception. The most common is the mode WDS Bridge (Wireless Distribution System), which allows you to connect routers wirelessly. A more advanced option is the Client or Client Bridge, where the router connects to another network like a regular device (laptop or phone), but then distributes the internet further. The third option is the "Wi-Fi" mode. Repeater (A repeater) which simply amplifies the signal, but often cuts the speed in half.
To check, go to the web interface of your device by entering the IP address in the browser (usually it is 192.168.0.1 or 192.168.1.1). Find the section related to wireless mode. If you see options like "Operating Mode," "Wireless Mode," or "Operating Mode," check the drop-down list. The presence of options like "Client," "Bridge," "WDS," or "Repeater" means you can begin the experiment.
- π‘ WDS β a classic method of combining networks, requires configuration on both routers and often only works between devices of the same brand.
- π» Client Bridge β turns the router into a network card, ideal for connecting devices with a LAN port (Smart TV, set-top boxes) to Wi-Fi.
- π Repeater - simple signal amplification, but with a loss of speed and the creation of a separate subnet (often).
- π Universal Client β a universal client that allows you to connect to any access point, regardless of the manufacturer.
β οΈ Please note: Firmware functionality is constantly changing. If you don't find the settings you need in the standard menu, the manufacturer may have reduced the functionality. In this case, it's worth checking the manufacturer's website for alternative firmware (for example, OpenWrt or DD-WRT), but this requires advanced skills.
IP Address Conflict and LAN Network Preparation
One of the most common errors when setting up a router-to-router connection is an IP address conflict. By default, most home routers have the same address for logging into the settings, for example, 192.168.0.1If you connect two such devices to the same network, chaos will result and neither of them will work correctly.
To avoid this, configure the receiver (second router) in isolation. Disconnect it from the internet and the main router. Connect to it from a computer via cable or Wi-Fi. Go to the LAN (Local Area Network) settings and change the device's IP address. For example, if the main router has an address 192.168.0.1, then set the receiver 192.168.0.250 or 192.168.0.2.
It is also critically important to disable the service on the receiver DHCP serversThere should only be one address-distributing router on the networkβthe main router. If DHCP remains enabled on the second device, your devices may receive incorrect gateway settings and lose internet access, even if the Wi-Fi signal is strong.
After changing the IP address and disabling the DHCP server, save the settings. The device may reboot. Now you'll need to log in to its interface using the new address you just assigned. Make sure the computer automatically received an IP address (DHCP mode), or manually assign a static address on the same subnet to continue setup.
Setting up WDS (bridge) mode using TP-Link and Asus as examples
Let's look at the setup process using popular brands as an example, as interfaces may vary. For routers TP-Link (Older and some newer models) often use WDS mode. Go to "Wireless" -> "Wireless Settings." Check the "Enable WDS Bridging" box.
Once enabled, a "Survey" or "Scan" button will appear. Click it to have the router search for available networks. Select your main router's network from the list. The system will ask you to select the encryption type (usually WPA2-PSK) and enter the main network's Wi-Fi password. It's important that the channel on both routers be set to the same value (e.g., 1, 6, or 11) and not set to "Auto."
For devices Asus The process is different. In the admin panel, go to "Administration" -> "Operating Mode." Select "Bridge Mode" or "Repeater Mode" if bridging isn't supported. In bridge mode, Asus often requires a cable connection, but in "Media Bridge" or "AiMesh" mode (for compatible models), a wireless connection is possible. Follow the quick setup wizard, which will prompt you to select the target network.
- π Encryption β must match on both devices (WPA2-PSK AES recommended).
- πΆ Channel - Fix the channel manually so that the bridge is not broken when the main router switches frequencies.
- π SSID β the network name on the receiver can be made the same as on the main one, for seamless roaming (although this is not true roaming), or different, so that you can understand which device you are connected to.
β οΈ Important: When setting up WDS, make sure the MAC address of the main router is entered in the receiver settings if automatic scanning does not work. Some older models require manual entry of MAC addresses to authorize the bridge.
Client Mode and Universal Settings
Mode Client (Client) is often considered more stable than WDS, especially if you need to connect a device that doesn't have a Wi-Fi module (such as a desktop PC or Smart TV) but does have a LAN port. In this mode, the receiving router doesn't create its own Wi-Fi network for phones (although some models allow you to operate as both a client and an access point simultaneously), but simply broadcasts the internet connection it receives over the air to its LAN port.
To set up, find the "Network" or "Internet" section and select "Wireless" or "Client" as the connection type. You'll be prompted to scan your surroundings. Select the primary network and enter the password. Once successfully connected, the WAN or global internet indicator on the receiver should light up, indicating a connection.
An important point here is DNS configuration. In client mode, it is often recommended to manually enter DNS servers (for example, from Google). 8.8.8.8 or Yandex 77.88.8.8) to speed up page loading. This can be done in the WAN settings section. Also, check the MTU (packet size) β sometimes reducing it to 1400 or 1350 helps avoid connection drops on wireless bridges.

If your router supports the mode Universal ClientThis is the best option for heterogeneous networks. It allows you to connect to any access point, even if it doesn't support WDS. In this case, the second router is completely transparent to the devices connected to itβthey will be on the same subnet as the main router's devices, which is convenient for setting up a local network (printers, files).
Setting up seamless Wi-Fi and working with SSIDs
Many users want their phones to automatically switch between the main router and the receiver without losing the connection. For this, network names (SSID) and the passwords on both devices must be identical. However, this does not create a real Roaming (802.11r/k/v), but merely imitates it. The client device (smartphone) decides for itself when to switch to a stronger signal, and often clings to the weak signal of a distant router until the very end.
To improve the situation, you can experiment with the transmitter power. On the main router, which is located in the center, you can reduce the signal power (for example, to 50-70%) so that devices release it more quickly and search for the receiver in the distant room. On the receiver, on the other hand, the power should be cranked up to maximum.
Another consideration is frequency bands. If both routers are dual-band (2.4 GHz and 5 GHz), it's best to configure the bridge on the 5 GHz band (it's faster and less congested), and leave clients broadcasting on 2.4 GHz if longer range is needed, or on both. However, remember: WDS bridging often only operates on one band, and if you link routers on 5 GHz, broadcasting on 2.4 GHz may not be possible on older models.
