It's quite common to need to extend a wireless network's coverage or connect a desktop device to the internet where the provider's cable physically doesn't reach. The standard scenario involves using a primary router that broadcasts the signal and additional equipment that receives it. Many users don't even realize that their old, unused router can become a powerful amplifier or a fully-fledged receiver, capable of broadcasting internet over a twisted pair cable to a computer, TV, or game console.
Technically, the process of turning a router into a receiver is called mode configuration. client (Client Mode) or mode bridge (Bridge/WDS). Unlike a simple repeater, which merely duplicates the signal, in client mode the device receives the wireless signal from the main access point, decodes it, and transmits it further, often providing a more stable connection for wired devices. This allows you to create a unified local network, where all devices connected to the second router can see each other and access network resources as if they were connected directly to the main gateway.
The implementation of this feature depends on the hardware platform and firmware version of your device. Some models, especially enterprise-class ones or firmware from alternative developers like OpenWrt or DD-WRT, provide flexible configuration tools. At the same time, budget home models may have limited functionality, with WiFi reception hidden or absent altogether. Before setting up, it's crucial to ensure your device supports this mode. Wireless Client or WDS Bridge, since without hardware support, software manipulations will not produce results.
Fundamental differences between router operating modes
To properly configure the equipment, it's important to clearly understand the difference between the operating modes, as selecting the wrong one will render the network inoperable. Router mode involves creating a dedicated subnet with NAT, where the device acts as a gateway between the WAN and LAN. Access Point mode typically involves a wired internet connection and sharing it via WiFi. We're interested in the scenario where the WAN port is unused, and the internet is received over-the-air by antennas.
Mode client Client mode turns the router into a wireless network card. In this mode, the device connects to another WiFi network like a regular device (laptop or phone), but then distributes the received internet through its LAN ports. An important feature is that in pure client mode, the native wireless network on the second router is often disabled to avoid conflicts, although some models allow both receiving and distributing a signal on a different frequency.
Mode bridge A WDS Bridge or Universal Repeater works differently. It not only connects to the main network but also creates its own access point with the same or different SSID. Devices connected to such a bridge can communicate with devices on the main network. However, using WDS often requires configuration on both routers and can reduce overall channel throughput by half due to protocol peculiarities.
⚠️ Note: When switching to client or bridge mode, the DHCP server function on the second router often needs to be manually disabled to avoid creating a NAT cascade or addressing conflicts. In some firmware versions, this happens automatically, while in others, it requires manual intervention in the LAN settings.
The choice between modes depends on your goals. If you simply need to connect a Smart TV via cable where WiFi coverage is available, client mode is suitable. However, if you need to extend your wireless network coverage to the second floor of your home while still being able to connect devices wirelessly, it's better to use repeater mode or a universal bridge, which supports both receiver and transmitter operation simultaneously.
Preparing equipment and resetting settings
Before making any changes to your network equipment, we strongly recommend performing a full factory reset. This will eliminate any remaining configurations from previously using the router as your default gateway. A factory reset is especially important if the device was previously used with a different provider or had static IP addresses that conflict with your current network.
To reset, find the button on the device body. Reset or WPS/ResetDepending on the model, you need to press and hold it for 10-15 seconds while the power is on, until the indicators blink simultaneously. After this, the router will reboot, and its IP address will return to the factory default value indicated on the sticker on the bottom of the case. This is usually 192.168.0.1 or 192.168.1.1.
Connect your computer or laptop to one of the LAN ports of the router you're configuring using an Ethernet cable. Don't connect this router to the main WiFi network yet; the configuration is performed locally. Make sure your computer's network card is set to obtain an IP address automatically (DHCP) so that it can receive an address from the factory router.
☑️ Preparing to repurpose your router
Basic interface and LAN settings
Open your browser and enter your router's IP address in the address bar. After entering your login and password (often admin/admin) you will be taken to the control panel. First, you need to change the IP address of the router itself in the local network to avoid conflict with the main router. If the main router has an address 192.168.1.1, then the custom one needs to be assigned, for example, 192.168.1.250.
The setting is made in the section Network → LANChanging the address is necessary so that you can access the management interface again after switching to client mode. In receive mode, the WAN port often stops functioning as a management input, and the address may change or become unavailable via the old path. After changing the IP, the router will prompt you to reboot. Do so and log in using the new address.
The next important step is setting up the wireless module to search for networks. In the wireless network section (Wireless) you need to select the operating mode. It can be called Client, Station, WDS or Repeater. Select the option that best suits your needs. For cable internet, choose ClientTo expand your WiFi range, select Repeater or Universal Repeater.
In some interfaces, such as TP-Link or Asus, there is a special quick setup wizard (Quick Setup or Operation Mode), which automatically switches the device to the desired mode. This simplifies the process for beginners, but manual mode gives more control over security settings and the communication channel.
Finding a network and setting up a wireless connection
After selecting the operating mode, you need to specify which network the router will connect to. Most modern interfaces have a scanning function (Scan or Survey). Click this button to see a list of available wireless networks within range.
In the list that appears, find the SSID of your primary network. Select it and click the connect button. The system will ask you to enter a security key (Wi-Fi password). Make sure the encryption type matches the settings of your primary router (usually WPA2-PSK or WPA3). Encryption type mismatch is the most common cause of connection errors.
An important parameter is the wireless channel. In client or bridge mode, it is best to set the channel value to Auto Or hard-code the same channel as the main router if you're using WDS mode. For universal client mode, channel locking isn't always necessary, but it can improve connection stability in noisy environments.
⚠️ Note: Interfaces and menu item names may vary depending on the firmware version and manufacturer. If you don't find an exact match, look for synonyms: Station instead of Client, Bridge instead of WDS. Always consult the official documentation for your specific model.
After entering the password and selecting the network, save the settings. The router will attempt to establish a connection. The wireless network indicator on the router should light up or change its blinking pattern, indicating a successful connection to the access point. If the connection fails, check the password and ensure that MAC address filtering is not enabled on the main router.
Features of WDS bridge configuration
WDS (Wireless Distribution System) mode allows you to combine multiple wireless networks into one. Unlike a simple client, WDS requires configuration on both ends of the connection. The primary router must be aware of the secondary router's existence and allow it to connect. This is a more complex but functional method, allowing for the transmission of broadcast packets, which are necessary for some smart devices and network printers.
To configure WDS on the main router, enable this feature, specify the MAC address of the second router, and set the communication channel (e.g., channel 6). On the second router, enable WDS, scan the main router's network, and specify its MAC address (BSSID). Both devices must operate on the same channel and use the same encryption type.
A critical step is to disable the DHCP server on the second router when setting up a WDS bridge. Only the main router should distribute addresses. Leaving DHCP enabled on both devices will create IP address chaos on the network, and the devices will lose internet access.
Why might WDS reduce speed?
WDS technology requires a data packet to be sent from the client to the router, then from the router to the main router, and back again. This doubles the overhead at each node. Furthermore, older WDS standards may limit the speed to 54 Mbps, even if the equipment supports higher speeds.
Setting up DHCP and distributing the Internet via cable
If your router is operating in Client Mode and you want to share internet access through the LAN ports to a computer or set-top box, you need to ensure the DHCP server on this router is enabled (unless it's using a transparent bridge). In Client Mode, the router receives one IP address from the main network (as a client) and distributes its IP addresses to devices connected via cable (as a server).
However, if you're setting up a transparent bridge, you need to disable the DHCP server. You can test the operation by connecting your laptop with a cable to the LAN port of the configured router. If the laptop receives an IP address within the main network range and has internet access, the setup was successful.
For stable operation, we recommend reserving an IP address for the second router in the main router's settings. This is done using the MAC address of the second device's WAN or WLAN interface. This way, you'll always know exactly which address your "receiver" is using on the network.
| Parameter | Main router (Distributes) | Second router (Receives) | Comment |
|---|---|---|---|
| Opening hours | Router / AP | Client / WDS | Key difference in functionality |
| LAN IP address | 192.168.1.1 | 192.168.1.250 | Must be in the same subnet |
| DHCP Server | On | Disabled (for bridge) / Enabled (for client) | To avoid conflicts |
| WiFi channel | Fixed (1-13) | Same or Auto | For WDS, the channel is mandatory. |
| Encryption | WPA2-PSK (AES) | WPA2-PSK (AES) | Must match exactly |
Diagnosing problems and common mistakes
Even with proper setup, connection stability issues may arise. A common cause is a weak signal. The client router must be within range of the main router for reliable reception. If the signal strength indicator shows 1-2 bars, speed will be low and ping high. Use an intermediate position or an external antenna to improve reception.
Another problem is the incompatibility of equipment from different manufacturers in WDS mode. The WDS standard is not strictly unified, so the bridge between TP-Link And D-Link It may not work. In such cases, it is better to use the universal client mode or reflash the firmware to OpenWrt, which provides better compatibility.
It's also worth paying attention to the frequency range. If the main router only broadcasts 5 GHz and the second one only supports 2.4 GHz, you won't be able to connect them. Make sure both devices operate in compatible bands. Dual-band routers (Dual Band) are preferable for organizing bridges, since they can receive a signal at 5 GHz and distribute it at 2.4 GHz without losing speed.
Frequently Asked Questions (FAQ)
Is it possible to connect routers from different brands in bridge mode?
In Client mode, yes, this usually works without problems, as it uses a standard protocol for connecting a station to an access point. In WDS (bridge) mode, compatibility is not guaranteed, as manufacturers often implement this standard differently. It's best to use equipment from the same brand or use standard firmware.
Will my internet speed drop when connecting via a WiFi bridge?
Yes, speed will inevitably drop. In repeater or client mode, speed loss can range from 20% to 50% of the original, depending on signal quality, interference level, and the standard used (802.11n/ac/ax). In practice, if the input speed is 100 Mbps, you'll get 40-60 Mbps through the bridge, which is plenty for video streaming.
Is a cable required between routers in client mode?
No, in Wireless Client or WDS mode, a cable between the routers is not required. Communication occurs over the air. The cable (twisted pair) is used only to connect end devices (PCs, TVs) to the LAN ports of the receiving router.
What should I do if the router doesn't see the main router's network when scanning?
Check that the main network's SSID isn't hidden (use the "Hide SSID" option). If the network is hidden, scanning won't reveal it—you'll need to enter the name and settings manually. Also, make sure the routers are close enough to each other and operate on a compatible frequency band (2.4 or 5 GHz).
