The problem of "dead zones" in an apartment is familiar to many: a router may be powerful, but the signal barely picks up in a distant room, and video calls drop out. Often, physically running a cable through the entire apartment is impossible or simply undesirable for aesthetic reasons. In such situations, wireless bridge technology comes to the rescue, allowing you to connect two parts of the network without unnecessary wiring.
Creating a WiFi bridge allows you to broadcast internet from your main router to a remote device, which in turn distributes the signal further or connects wired devices. This method is ideal for connecting Smart TV, game consoles, or setting up a separate guest network. However, for the system to operate stably, it's necessary to select the right equipment and configure the settings, which we'll discuss below.
Before setting up, it's important to understand that the speed of such a connection will always be lower than with a direct wired connection. However, for watching 4K video or surfing the internet, the bandwidth is usually more than sufficient. The key is to ensure a clear line of sight or minimal obstructions between the transmitting and receiving devices.
Operating principle and selection of equipment
The technology that allows two routers to be connected over the air is most often based on the standard WDS (Wireless Distribution System). The method consists of one router operating as an access point, while the second connects to it as a client, receiving and transmitting internet. To implement this setup, you'll need two wireless routers, preferably the same model or at least from the same manufacturer.
Not all budget devices support the bridge function out of the box. Before purchasing or setting up, be sure to check your hardware specifications for support. Repeater, Bridge or WDSThis feature can often only be activated after flashing the device to an alternative firmware, but it's worth trying the standard tools first.
Antennas deserve special attention. If you plan to connect devices located at different ends of the apartment with thick walls between them, standard antennas may not be sufficient. In some cases, it may be worth upgrading to more powerful, high-gain models.

- 🔌 Ethernet cable for initial setup of each device.
- 📱 A smartphone or laptop with access to the router's web interface.
- 🔑 Pre-known login details for the admin panel (login and password).
Preparing the main router for operation
Setup begins with the main device, which is already connected to the ISP and is distributing internet. You need to log in to its web interface, usually at 192.168.0.1 or 192.168.1.1. In the wireless network settings menu (Wireless) you need to fix the channel on which the WiFi operates so that the second router can reliably connect to it.
Automatic channel selection ("Auto") isn't suitable in this case, as rebooting the router may cause the frequency to change, breaking the bridge. Select any available channel, such as 1, 6, or 11 for the 2.4 GHz band, and save the settings. Also, make sure the "Auto" function is enabled. WDS or "Bridge" if it is explicitly present.
⚠️ Note: When changing the WiFi channel, all connected devices may temporarily lose connection. This is normal, and the network will be restored within 1-2 minutes.
Next, you need to write down or copy the MAC address of the primary router, as you'll need it to configure the second device. This address is usually found on a sticker on the bottom of the case or in the Status / State web interface. Without precise knowledge of the MAC addressing of the protected bridge, it is impossible to determine the MAC addressing of the protected bridge.
☑️ Checking the main router
Setting up a second router in bridge mode
The second router that will receive the signal must be configured in client or bridge mode. First, connect to it via cable or WiFi (if it broadcasts its signal by default) and go to the settings. Find the section responsible for the operating mode and switch it to Repeater, Bridge or WDS.
After activating bridge mode, start a scan for available networks. You should see the SSID of your main router in the list. Select it and enter the password for your main WiFi network. The key here is to match the encryption type: if the main router has WPA2-PSK, then the same should be indicated on the second one.
Main router: Channel 6, SSID HomeNet, Security WPA2-PSK
Second router: Mode WDS, Connect to HomeNet, Pass:
The most important detail is IP addresses. To avoid address conflicts, the LAN IP of the second router must be different from the IP address of the first. If the main router has an address 192.168.0.1, then the second one needs to be assigned, for example, 192.168.0.2This must be done before switching to bridge mode, otherwise you may lose access to settings.
What to do if the routers are of different brands?
Creating a WDS bridge between routers from different manufacturers (for example, TP-Link and Asus) is extremely difficult, and often impossible, due to differences in protocol implementation. In such cases, it's best to use Universal Repeater mode, if supported, or upgrade both devices to OpenWRT.
Organizing a wired connection via a bridge
One of the main purposes of creating a bridge is often to connect devices without a WiFi module, such as old TVs or desktop computers. After successfully setting up a wireless connection between the routers, you can use the LAN ports of the second device as regular network ports.
Simply connect an Ethernet cable from any available port. LAN Connect a second router to your device. To the system, this will appear as a direct wired connection to the main network. The DHCP server running on the main router will automatically assign an IP address to the connected device.
| Parameter | Main router | Second router (Bridge) |
|---|---|---|
| Opening hours | Access point (AP) | WDS / Bridge / Client |
| IP address | 192.168.0.1 | 192.168.0.2 |
| DHCP Server | On | Turned off |
| SSID (Network Name) | Home_WiFi | Home_WiFi (or any other) |
It's worth noting that the data transfer speed via the cable from the second router will depend on the quality of the wireless signal it receives from the first. If the signal indicator on the second device shows low, the cable speed will also be low.
Problems with connection speed and stability
Creating a wireless bridge inevitably results in a speed drop, sometimes as much as 50% of the original. This is because the second router's radio module is forced to simultaneously receive data from the first router and transmit it to the client, operating in half-duplex mode. In noisy bands, losses can be even more significant.
If you experience constant connection drops or very low speeds, try repositioning the antennas. They should be aligned parallel to each other. It's also a good idea to check whether household appliances, such as microwaves or baby monitors, that operate on the 2.4 GHz frequency are interfering with the network.
⚠️ Note: Router firmware interfaces are constantly being updated. The layout of menu items may differ from those described, so look for similar function names in your device model.
To diagnose connection quality, you can use utilities like inSSIDer or built-in WiFi analysis tools in smartphones. They will show the signal strength (RSSI) and noise level. A signal level above -65 dBm is considered optimal. If the value is lower (for example, -80 dBm), the stable operation of the bridge is questionable.
- 📉 A speed drop of up to 50% is normal for WDS technology.
- 📶 Use the 5 GHz band for a less noisy environment.
- 🔄 Update your router firmware to the latest version.
- 🚫 Avoid installing the bridge near metal structures.
Alternative solutions for network expansion
If a traditional bridge between two routers doesn't produce the desired result or the setup seems too complicated, there are more modern solutions. One of them is the technology Mesh, which allows you to create a single seamless network from multiple modules. Unlike WDS, Mesh systems automatically select the optimal path for traffic and do not require manual channel configuration.
Another option is to use PowerLine adapters. These devices transmit the internet signal through the regular electrical wiring in your apartment. Simply plug one adapter into a socket near the router and connect them with a cable, and the second adapter into a socket in a distant room. This solution is often more stable than a wireless bridge if the wiring in your home is of high quality.
The choice between a WiFi bridge, a mesh system, or PowerLine depends on your specific home and budget. Bridging on older routers is a free way to revive your network, but it requires time for setup and testing.
Is it possible to create a bridge between routers from different manufacturers?
Technically, the WDS standard isn't strictly unified, so different manufacturers implement it differently. For example, connecting a TP-Link and Asus router in WDS mode is often unsuccessful. However, the "Universal Repeater" mode has a higher chance of success, as it emulates the connection of a regular client device.
How many routers can be connected in a chain using a bridge?
Theoretically, it's possible to create a chain of multiple devices, but in practice, using more than two links (one master and one bridge) is not recommended. Each additional link cuts speed in half and increases latency (ping), making the network virtually unusable.
Does WiFi encryption affect bridge speed?
Yes, it does. Using modern encryption standards. WPA3 or even WPA2 Requires the router's processor's computing resources. On older or weaker models, enabling encryption can significantly reduce the maximum bridge throughput. However, leaving the network passwordless is strongly discouraged for security reasons.
Do the network names (SSID) on both routers need to match?
Matching network names isn't required for the bridge itself (data transfer). You can name the network on the second router whatever you like. However, if you want devices to automatically switch between routers (roaming), it's best to set the same network name and password, although a simple WDS bridge won't provide full seamless roaming.
