Connecting a router to another via Wi-Fi: 3 working methods + step-by-step setup

• Go to Network → LAN.
• Change the IP address so that it is in the same subnet as the main router, but does not conflict with it. For example, if the main router has 192.168.0.1, install 192.168.0.2.
• Save the settings and reboot the router.

After rebooting, the secondary router should connect to the primary router via WDS. Test the connection by connecting to its Wi-Fi (the network name should match the primary one unless you changed the SSID).

⚠️ Attention: If the Internet does not work after setting up WDS, check:

• Do they match? Wi-Fi channels on both routers.
• Is it entered correctly? MAC address main router.
• Is it disabled? DHCP on the secondary device.

Router interfaces may vary. If you can't find the item you're looking for, search for similar options using keywords: WDS, Bridge, Repeater.

3. Method 2: Bridge mode

Bridge (bridge mode) is an alternative to WDS, which also allows you to connect two routers via Wi-Fi, but with some differences:

• 🔗 A "bridge" is being created between networks, but SSID may differ (as opposed to WDS).
• 📡 Supported by most routers, including models without WDS.
• 🔌 You can connect wired devices to the secondary router (via its LAN ports).

Cons:

• 🔄 No automatic roaming — you will have to manually reconnect between networks.
• ⚙️ More difficult to set up, than the Repeater mode.

Bridge is suitable if:

• Your routers do not support WDS.
• You need divide the networks (for example, for guests and main devices).
• You want connect via cable devices in a remote room.

Step-by-step Bridge setup

Example for routers ASUS (for other brands the logic is similar):

1. Setting up the main router:
   • Make sure Wi-Fi is turned on and working stably.
   • Write it down network name (SSID), password And channel.
   • If used DHCP, leave it on.
2. Setting up a secondary router:
   • Reset it to factory settings.
   • Connect to it via cable and log into the web interface.
   • Go to Administration → Operating Mode (or Operation Mode).
   • Select Bridge Mode or Wireless Client.
   • Save the settings and the router will reboot.
3. Connecting to the main network:
   • After rebooting, go to the section Wireless network.
   • Enable network search and select the SSID of the main router.
   • Enter your password and save your settings.
   • Turn it off DHCP on the secondary router (in the section LAN or DHCP).
   • Change IP address secondary router so that it does not conflict with the main one (for example, 192.168.1.2, if the main one is 192.168.1.1).

• Connect to the secondary router's Wi-Fi (if you haven't changed the SSID, it may remain the factory one).
• Check your internet access.
• If necessary, connect the devices via cable to the LAN ports of the secondary router.

⚠️ Attention: In Bridge mode, the secondary router does not distribute Wi-Fi by default — it works as a client of the main network. To make it also distribute Wi-Fi, you need to enable this function in the wireless network settings (sometimes you need to switch to the Universal Repeater or Range Extender).

4. Method 3: Repeater mode

Repeater (repeater) is the easiest way to extend your Wi-Fi coverage. In this mode, the secondary router repeats the signal primary, increasing the network's range. Main advantages:

• ⚡ Extremely simple setup (often just pressing one button is enough).
• 🔄 There is no need to change IP addresses or disable DHCP..
• 📶 Suitable for temporary signal amplification (for example, at the dacha).

Cons:

• 📉 Severe loss of speed (up to 50% and more).
• 🔌 You cannot connect devices via cable. to the secondary router (LAN ports are disabled).
• 🔄 One network name (SSID), But there is no seamless roaming — devices may get stuck on a weak signal.

Repeater is suitable if:

• You need quickly boost the signal without complex settings.
• You are using mobile devices (smartphones, tablets), not desktop PCs.
• Your secondary router does not support WDS or Bridge.

Step-by-step Repeater setup

Example for routers Xiaomi (for other brands steps may vary):

1. Preparation:
   • Place the secondary router in the area stable signal main (at least 2-3 divisions on the indicator).
   • Reset it to factory settings (button Reset).
2. Enter settings:
   • Connect to the secondary router's network (by default it's called Xiaomi_XXXX or similar).
   • Open the web interface at miwifi.com or 192.168.31.1.
3. Selecting Repeater mode:
   • Go to Additional settings → Operating mode.
   • Select Repeater mode.
   • Click Next.
4. Connecting to the main network:
   • The router will prompt you to select a network to replicate—find your primary Wi-Fi network in the list.
   • Enter the password for the main network.
   • Set up the network name (SSID) of the extender:
     • Leave it the same, like the main router (simplifies connection).
     • Or ask unique name (For example, MyWiFi_Repeater).
   • Save the settings.

• Connect to the repeater network.
• Check your internet speed (for example, on speedtest.net).
• If the speed is too low, try placing the router closer to the main one.

On some routers (for example, TP-Link) the repeater mode is enabled through the section Wireless Mode → Repeater Mode or button Range Extender in the mobile application.

5. Comparison of connection methods: which one to choose?

To decide on a method, answer the questions:

• 📶 Do you need a seamless network? → Choose WDS.
• 🔌 Do you need to connect devices via cable? → Customize Bridge.
• ⚡ Need to quickly and easily boost your signal? → Use Repeater.
• 💻 Is top speed important? → It's better to lay it out cable between routers.

If your routers one model or brand (for example, both TP-Link or ASUS), it is better to use WDS — it will ensure maximum compatibility. It will work for routers from different manufacturers. Bridge or Repeater.

⚠️ Note: Some budget routers (for example, D-Link DIR-300 or Tenda N301) do not support WDS. Before purchasing a secondary device, check its specifications on the manufacturer's website.

6. Common mistakes and their solutions

Even with proper settings, the connection may be unstable. Let's look at the most common issues:

🔴 There is no connection between the routers

Possible causes and solutions:

• 🔍 Invalid MAC address In WDS/Bridge settings → Check and re-enter the address of the main router.
• 📡 Different Wi-Fi channels → Set a fixed channel on both routers (for example, 6).
• 🔒 Security parameters mismatch → Make sure the encryption type (WPA2-PSK) and password match.
• 📶 Weak signal → Move the secondary router closer to the primary one.

🟡 There is internet, but the speed is very slow

How to improve:

• 📶 Change the Wi-Fi channel to a less busy one (use Wi-Fi Analyzer).
• 🔄 Switch to 5 GHz (if both routers support this range).
• 📡 Reduce the transmit power on the main router (sometimes helps with interference).
• 🔌 Use a wired connection between routers, if possible.

🟢 The connection is frequently broken

Possible reasons:

• ⚡ Unstable power supply → Connect routers via uninterruptible power supplies (UPS).
• 📡 Interference from other networks → Change the channel or use 5 GHz.
• 🔄 Outdated firmware → Update the software on both routers.
• 📱 Too many connected devices → Limit the number of clients on the secondary router.

If the secondary router in Bridge or Repeater mode periodically "forgets" settings and resets itself, try disabling the power saving feature in its settings (if available). This issue is common on routers running OpenWRT-based firmware.

7. Alternative ways to expand the network

If connecting your router to another router via Wi-Fi doesn't produce the desired result, consider other options:

• 🔌 Wired connection (LAN-WAN):
  • Maximum speed and stability.
  • It is necessary to lay a cable (can be used Powerline adapters for transmitting a signal through electrical wiring).
• 📡 Mesh systems (Wi-Fi 6):
  • Ready-made solutions for seamless roaming (for example, TP-Link Deco, Google Nest Wi-Fi).
  • More expensive, but easier to set up and more reliable.
• 📶 Access Points:
  • They connect via cable, but distribute Wi-Fi.
  • Ideal for large offices or homes with wired infrastructure.
• 🔄 3G/4G router as a backup:
  • Useful if the main internet is unstable.
  • You can set up automatic switching when the connection is lost.

If you are choosing between two routers And Mesh system, please take into account:

• 💰 Mesh is more expensive, but easier to manage.
• ⚙️ Two routers are cheaper, but require manual configuration.
• 📶 Mesh is better suited for larger homes (3+ rooms).
