How to connect a router to another router's Wi-Fi: 3 proven methods

Want to expand your Wi-Fi coverage in your home or office, but can't run a cable from your main router? The solution is simple: connect a second router. over a wireless network to the first one, using it as an internet source. This approach eliminates the need for Ethernet cables and creates a unified network with automatic switching between access points.

In this article we will look at three main ways connecting the router to another router's Wi-Fi: via repeater mode, bridge (WDS) And client modeEach method has its own nuances, so we will explain in detail which option to choose depending on your router model (TP-Link, ASUS, Keenetic, MikroTik and tasks. You will also learn how to avoid common mistakes, such as double NAT or IP address conflicts that can slow down the network.

If you're unsure which mode to choose, use our comparison table at the end of the first section. And for those who've already tried setting up a connection but encountered problems, we've added FAQ with solutions the most common problems, from no internet to low speed.

1. Which connection method to choose: comparison of modes

Before you begin setting up, decide which operating mode of the second router is right for you. This will affect not only the connection process, but also network performance, connection stability and even security.

Let's consider three main options:

• 🔄 Repeater mode - the second router repeats signal of the main one, creating a single network with the same name (SSID). Suitable for wireless coverage extension, but reduces speed by approximately 30-50% due to double data transfer.
• 🌉 Bridge mode (WDS, Wireless Distribution System) — both routers operate as peer access points on the same network. Allows you to connect devices to either router without losing speed (if supported). 802.11r). Requires hardware compatibility.
• 🖥️ Client Mode — the second router connects to the main one like a regular device (e.g., a smartphone), and then distributes the Internet via cable or Wi-Fi. Useful for connecting wired devices (e.g., Smart TV or IP cameras) within the coverage area of ​​someone else's Wi-Fi.

To make your choice easier, use the table:

⚠️ Attention: If your router does not support WDS or Repeater Mode, check if the firmware can be updated. For example, Keenetic And ASUS New modes are often added in new software versions.

2. Preparing for connection: what you need to do before setting up

Before connecting routers, there are a few essential steps you should take. This will help you avoid common mistakes, such as: IP address conflict or unstable connection.

Preparation checklist:

Pay special attention Wi-Fi channelsIf the main router is operating on the channel 6, and the second one is on 11, the signal will be weaker due to interference. It is optimal to use the same channel or close ones (for example, 1 And 6 for the 2.4 GHz range).

Also check if your router supports it roaming (802.11k/v/r). If so, devices will automatically switch between access points without losing the connection. This feature is available in most modern models. ASUS, TP-Link Archer And Keenetic.

⚠️ Attention: If you are setting up a bridge (WDS) between routers from different manufacturers, make sure they support the same security standards (WPA2-PSK or WPA3). Otherwise, the connection will be unstable.

3. Method 1: Connecting in repeater mode

This method is the simplest and works for most home routers. The second router will be repeat the signal the main one, creating a unified network. The main disadvantage is the connection speed will decrease by about half, since data is transmitted twice: from the main router to the repeater and from the repeater to the device.

Let's look at the setup using an example TP-Link Archer C6:

1. Connect the second router to your PC via cable and log into its web interface (usually at 192.168.0.1 or 192.168.1.1).
2. Go to the section Additional settings → Operating mode and select Wi-Fi Booster (Range Extender).
3. Click Next and select the main router's network from the list. Enter the password.
4. Set up a name for the new network (SSID). We recommend leaving it the same as the main router, but with the suffix _EXT (For example, MyWiFi_EXT).
5. Save the settings and reboot your device.

For ASUS RT-AX55 the path will be different: Administration → Operation Mode → Repeater Mode.

⚠️ Attention: If after setting up the devices do not connect to the repeater, check if the box is checked Isolate clients (AP Isolation) in the main router settings. This feature blocks data exchange between devices on the same network.

4. Method 2: Setting up a WDS bridge for two routers

Mode WDS (Wireless Distribution System) allows you to connect two routers into one network without loss of speed, if both devices support this standard. Unlike a repeater, both routers act as equal access points, and devices can connect to either one.

Example setup for Keenetic:

1. Log in to the web interface of the second router (192.168.1.1).
2. Go to Wi-Fi Network → Access Point and activate the option "Bridge Mode (WDS)".
3. From the list of available networks, select the main router and enter the password.
4. In the section IP addressing turn it off DHCP server, to avoid conflicts.
5. Set a static IP address for the second router (e.g. 192.168.1.2, if the main one has 192.168.1.1).
6. Save the settings and reboot your device.

For MikroTik The setup is more complicated and requires the use of WinBox:

/interface wireless
set wlan1 master-interface=none mode=station-wds ssid=MyWiFi_Main security-profile=my_profile
/ip address add address=192.168.1.2/24 interface=wlan1

⚠️ Attention: If the bridge is unstable after setup, check if the routers are using different Wi-Fi standards (802.11n vs 802.11ac). For stable operation, both devices must support the same protocols.

What to do if WDS is not working?

If the routers cannot see each other in WDS mode, try:

1. Set the same channel manually (for example, 6).

2. Disable encryption temporarily (leave Open) to check the connection.

3. Update the firmware on both devices.

4. Check the compatibility of standards (e.g. TP-Link TL-WR841N does not support WDS with ASUS RT-AX88U due to different chipsets).

5. Method 3: Client mode for connecting wired devices

This mode is useful if you need to connect a device to Wi-Fi. without a wireless module (For example, Smart TV, IP camera or game console). The second router acts as client the main network and distributes the Internet via cable.

Setting up an example D-Link DIR-615:

1. Connect to the router via cable and log into the control panel (192.168.0.1).
2. Go to Wi-Fi → Client and activate the mode «Client Mode».
3. Select the main router network and enter the password.
4. Turn it off DHCP server in the section Network → LAN.
5. Connect the device (eg. TV) To LAN port second router.

For Zyxel Keenetic the path will be like this: Internet → Connection → Connection Type: Wi-Fi Client.

⚠️ Attention: In client mode, the second router doesn't distribute Wi-Fi (if it's not supported by its functionality). To simultaneously distribute Wi-Fi and connect via cable, look for the option in the settings AP + Client or Universal Repeater.

6. Common mistakes and how to fix them

Even with proper setup, problems can still arise. Let's look at the most common ones and how to solve them:

• 🔌 There is no internet on connected devices:
  • Check if it is disabled DHCP server on the second router (if using bridge or client mode).
  • Make sure the routers' IP addresses are in the same subnet (e.g. 192.168.1.1 And 192.168.1.2).
  • Reboot both routers.
• 📶 Weak signal or frequent interruptions:
  • Reduce the distance between routers or use repeater as an intermediate link.
  • Change your Wi-Fi channel to a less busy one (use apps like Wi-Fi Analyzer).
  • Turn it off 802.11b in the settings of the main router (this will speed up the network for modern devices).
• 🔒 I can't access the settings of the second router.:
  • If you have changed its IP address, connect to it directly via cable.
  • Use the address you assigned manually (eg. 192.168.1.2).
  • Reset settings with the button Reset, if you forgot your login details.

⚠️ Attention: If after setting up the bridge (WDS) works unstable, check if the function is enabled Beamforming or MU-MIMO on the main router. These technologies may conflict with some models in bridge mode.

7. How to improve connection speed and stability

After successfully connecting the second router, you may encounter low speed or delaysHere are some ways to optimize your network:

• 🔄 Use the 5 GHz band:

  If both routers support 5 GHz, set up a connection on this band. It's less crowded and offers faster speeds, although it has a smaller coverage area.

• 📡 Set up Roaming Assist:

  In routers ASUS And TP-Link there is a function Roaming Assist, which helps devices switch between access points faster. Enable it in your Wi-Fi settings.

• 🔗 Disable unnecessary services:

  In the settings of the second router, disable IPv6, UPnP And QoS, if they are not in use. This will reduce the load on the processor.

• 🔋 Update the firmware:

  Manufacturers regularly release updates that fix compatibility issues. Check the latest version on the brand's website.

Also pay attention to placement of routers:

• 📍 Do not place them near metal objects or household appliances (microwaves, refrigerators).
• 🌿 Avoid places with thick walls or mirrors - they reflect the signal.
• 📏 The optimal distance between routers is 10-15 meters (for 2.4 GHz) or 5-8 meters (for 5 GHz).

8. FAQ: Answers to frequently asked questions

❓ Is it possible to connect a router to another router's Wi-Fi without losing speed?

Yes, if you use bridge mode (WDS)In this case, there is virtually no loss of speed, since both routers operate as equal access points. However, both devices must support WDS, otherwise you'll have to use repeater mode, which reduces speed by 30-50%.

❓ Why don't devices connect to the second router after setting up the bridge?

Possible reasons:

• Not disabled DHCP server on the second router.
• The routers' IP addresses conflict (for example, both have 192.168.1.1).
• Mismatch of safety standards (WPA2 vs WPA3).
• The distance between routers is too great.

Check the settings and reboot both devices.

❓ How can I make sure that there is only one network and not two different ones (MyWiFi And MyWiFi_EXT)?

To do this, set up identical SSID, password and channel on both routers. However, please note:

• Not all devices work well with roaming (automatic switching between points).
• In repeater mode, this may cause connection problems.
• Better to use WDS or Mesh systems (For example, TP-Link Deco or ASUS AiMesh).

❓ Is it possible to connect a third router to the chain?

Technically yes, but each new "jump" (repeater → repeater) reduces the speed in 2-3 timesThe optimal solution is to use Mesh system Or extend a cable to at least one of the access points. If daisy chaining is unavoidable, limit yourself to two routers: the main one and one repeater.

❓ Why is the speed through the second router lower than on the main one?

This is normal for repeater mode, as data is transmitted twice. To reduce losses:

• Use range 5 GHz (if supported).
• Reduce the distance between routers.
• Disconnect unnecessary devices from the main network.
• Check if the speed limit is enabled (QoS) on the main router.
