How to connect a router to another router via Wi-Fi: Bridge and Repeater Mode

Many users are familiar with the situation where the main router's signal doesn't reach distant rooms or the garage. Running a long Ethernet cable through the entire house is often unsightly or technically impossible due to structural features of the building. In such cases, creating a wireless bridge between the two devices is the ideal solution. This allows internet traffic to be transmitted without physical limitations using radio waves.

To implement this scheme, you will need a second router that will operate as a receiver or signal repeater. Modern devices based on OpenWrt, DD-WRT or proprietary shells from Asus And TP-Link Support this feature out of the box. It's important to understand that the speed on such a network will depend on the quality of the radio signal and interference.

Before you begin setting up, you need to make sure that your equipment supports operation in this mode. WDS (Wireless Distribution System) or Client BridgeThese technologies allow the device to receive a Wi-Fi signal and transmit it further, either via a cable or by creating a new access point. The setup process requires careful attention, as errors in IP addresses can lead to conflicts within the local network.

Selecting the right equipment and operating modes

Not all routers are equally adept at signal retransmission. Older models may only support WDS mode, which requires both devices to be the same brand or even model. Newer devices can work universally, receiving signals from any source. Support for this mode is key. Client or Repeater in the device firmware.

If you plan to connect devices from different manufacturers, for example, the main router from Keenetic and secondary from TP-Link, you will most likely have to use the mode WISP (Wireless Internet Service Provider) or ClientIn this mode, the secondary router connects to the primary router as a regular client (laptop or phone), but then distributes the received internet through its LAN ports or Wi-Fi. This is the most flexible option, although it creates a double NAT, which is not critical for regular surfing.

Pay attention to the frequency ranges. Dual-band routers that support the standards 802.11ac And 802.11ax, allow you to create a more stable connection. You can use the 5 GHz band for backhaul communication between routers, leaving the 2.4 GHz band for distribution to clients. This will significantly reduce the airtime load and increase the overall speed.

  • 📡 WDS mode: Ideal for homogeneous networks, requires configuration on both devices, and is transparent to clients.
  • 💻 Client mode: The secondary router becomes a network card, distributing the Internet only through LAN ports (Wi-Fi often disconnects).
  • 🔄 Repeater/Repeater Mode: Increases coverage area, but may reduce overall channel throughput by half.

⚠️ Attention: When using WDS mode, the MAC addresses of the devices must be manually entered into the settings of both routers. A single digit error will prevent the bridge from establishing.

It's also worth keeping in mind that router firmware is constantly being updated, and interfaces may differ from those described in the manuals. Always check the latest documentation on your equipment manufacturer's website before beginning any work.

Preparing to set up a wireless bridge

The first step is to properly prepare and reset the secondary router. Connect your computer to any LAN port on the secondary device using a cable. Make sure the primary router, which is already distributing internet, is turned on and functioning correctly. You will need to know its network name (SSID) and password to connect.

Access the secondary router's web interface. To do this, enter its IP address in the browser. By default, this is usually 192.168.0.1 or 192.168.1.1If the address matches the primary router's address, a conflict will occur. In this case, change the secondary device's IP address in the section LAN Settings to a unique one, for example, 192.168.1.254, if the main one has an address 192.168.1.1.

After changing the IP address, you'll need to reconnect to the router by entering the new address in your browser. Now it's important to disable the DHCP server on the secondary device if you're setting up bridge or repeater mode so it doesn't distribute IP addresses instead of the primary router. WISP or Client DHCP, on the other hand, must be enabled.

It's crucial to record the MAC address of the secondary router's wireless interface. This information will be needed to configure the primary device if you select WDS mode. You can find it on a sticker on the bottom of the device or in the "Settings" section. Status -> Wireless web interface.

Setting up the main router (Access point)

Now let's move on to setting up the main device that will broadcast the signal. Go to its control panel and find the wireless network section, often called Wireless or Wi-Fi SettingsHere you need to make sure that the WDS function is enabled or allowed. In some models, Asus This is in the section Administration -> System or directly in the Wi-Fi settings.

Set a static channel for your wireless network. For the 2.4 GHz frequency, it's recommended to use channels 1, 6, or 11 to avoid overlapping with neighboring networks. Automatic channel selection (Auto) in bridge mode often leads to connection interruptions, as routers can "lose" each other when changing frequencies.

In the security section, select the encryption type WPA2-PSK (AES). This is the most compatible and secure standard currently available. Avoid using mixed modes (TKIP+AES), as they may reduce speed or cause connection issues with older devices.

Parameter Recommended value Note
Channel 1, 6 or 11 Static only
Channel width 20 MHz For better range
Mode 802.11n / Mixed Depends on the clients
WDS Enabled If required
Why is the channel width 20 MHz?

A narrow channel provides greater signal power per unit frequency, which is critical for bridge stability over long distances. A 40 MHz channel provides speed in close range, but is highly susceptible to interference.

After making changes, be sure to click the button Save or ApplyThe router may reboot. Make sure the Wi-Fi network is available and devices can connect to it after the reboot.

Secondary Router Configuration (Client/Bridge)

On the second router, which we prepared earlier, you need to activate client mode. In the interface TP-Link This is often called Operation Mode -> Client or Wireless Bridge. U Asus in the section Administration -> Operating Mode need to choose Bridge Mode or Repeater.

Go to your wireless settings and start searching for available networks (Survey or Scan). In the list that appears, find the SSID of your primary router and select it. The system will automatically enter the MAC address of the primary access point. If manual entry is required, copy the MAC address from the previous step.

Enter the password for your primary Wi-Fi network. Make sure the encryption and channel settings exactly match those of your primary router. If your primary router is set to channel 6, then this channel should also be set to channel 6, even if it's selected automatically when joining the network.

⚠️ Attention: If you are using WDS mode, be sure to enter the secondary router's MAC address in the primary router's WDS settings, otherwise the connection will not be established.

After saving the settings, the secondary router will attempt to connect. The Wi-Fi indicator on the router should light up or change its blinking pattern, indicating a successful connection to the upstream network.

Checking the connection and diagnosing problems

After setting up both devices, connect your laptop or phone to the secondary router's network. Check for internet access. If pages aren't loading, try running the command ping 8.8.8.8 in the command line. If the ping works but websites don't open, check the DNS settings on the client device.

A common problem is incorrect IP address allocation. Make sure the secondary router receives its WAN IP address from the primary router (in client mode) or that its LAN IP is in the same subnet but doesn't conflict with the primary router's DHCP range.

📊 What problem are you facing?
There is no internet on the second router.
Slow connection speed
The routers don't see each other.
Everything works fine.

To diagnose the signal level, you can use utilities like inSSIDer Or use the built-in monitoring tools in the router firmware. The signal strength (RSSI) should be better than -70 dBm for stable operation. If the value is lower (for example, -85 dBm), consider moving the routers closer together or elevating them.

  • 🔍 IP Check: Make sure the client has received an address from the correct subnet (for example, 192.168.1.x).
  • 📶 Signal level: Check RSSI in Wireless Connection Status.
  • 🔥 Overheat: Long-term operation in bridge mode may heat up the device, check the case temperature.

Optimizing network speed and security

To ensure your network operates at maximum efficiency, it's recommended to separate the frequencies. If your routers are dual-band, configure the backhaul between them to use 5 GHz, while leaving 2.4 GHz for clients. This will avoid the speed loss typical with single-band repeaters, where the device both receives and transmits data on the same frequency.

For security, make sure both devices have a strong password. WDS mode has historically been vulnerable, so using WPA3 (if supported by both devices) or strict WPA2-AES Be sure to disable the WPS feature, as it is a known security vulnerability in wireless networks.

Update your router firmware regularly. Manufacturers frequently release patches that improve wireless connection stability and fix vulnerabilities. For older models, consider installing alternative firmware, such as OpenWrt, which provide more fine-grained control over the wireless bridge parameters.

⚠️ Attention: Settings interfaces may vary depending on the firmware version. If you don't see the feature described, look for it in the Advanced settings or update your router's firmware.

A properly configured router bundle can provide coverage for a large home or office without sacrificing speeds comparable to a wired connection. The key is to carefully check each setup step and ensure compatibility between operating modes.

Is it possible to connect routers from different manufacturers?

Yes, it's possible, but not in WDS mode. To connect devices from different brands (for example, Asus and TP-Link), you need to use the WDS mode. Client or WISP On the secondary router. In this case, it connects to the primary router as a regular Wi-Fi client.

Why does the speed drop when connecting a second router?

In repeater mode, speed can drop by up to 50%, as the device spends time receiving and transmitting data alternately on the same frequency. Using 5 GHz bridge mode or a wired connection (AP mode) solves this problem.

Do I need to disable DHCP on the second router?

If you are setting up Bridge or Access Point (AP) mode, DHCP on the second router must be enabled. turn off, so that only the main router distributes addresses. In Client/WISP DHCP mode, on the contrary, it should be included.

Which mode is better: WDS or Client?

WDS is better for network transparency (all devices are on the same subnet), but is difficult to configure across different brands. Client mode is universal and easier to configure, but it creates a subnet (double NAT), which may interfere with some games or torrents.
