How to connect two routers via Wi-Fi: detailed instructions with diagrams and settings

Connecting two routers wirelessly is a challenge faced by owners of large apartments, private homes, or offices where a single router doesn't provide a stable signal. However, simply placing a second router next to each other isn't enough: without proper configuration, both devices will create separate networks, with no automatic switching between them, and speeds can drop by a factor of two to three. In this article, we'll explore this. Three working methods for connecting routers via Wi-Fi (wireless!), their pros and cons, as well as step-by-step instructions for popular models TP-Link, ASUS And Keenetic.

It is important to understand that a wireless connection of routers is always inferior in stability and speed to a wired one (via cable) LAN or Ethernet). However, in cases where cable installation is not possible (for example, in a rented apartment or between floors of a building), a Wi-Fi bridge becomes the optimal solution. We will also cover the key mistake 90% of users makeWhy does the speed drop by 50% after setup and how to avoid it?

1. Methods for connecting routers via Wi-Fi: which one to choose?

There are three main methods for wirelessly linking routers, and each is suitable for different scenarios. The choice depends on whether you need a single network (with automatic switching between routers) or just need to extend the coverage area with a separate network name (SSID).

• 🔄 Bridge mode (WDS) - both routers create one network with the same SSID and a password. Devices automatically switch between them. Minus: speed may decrease by 30-50% due to double traffic encryption.
• 📶 Repeater mode — the second router works as a signal amplifier for the first one. Plus: easy setup. Minus: a separate network is created (for example, MyWiFi_EXT), and switching between routers is not automatic.
• 🖧 Client Bridge (Client Mode) — the second router connects to the first as a client, and devices can then be connected to it via cable or Wi-Fi. Perfect to connect Smart TV, game consoles or PCs in a remote room.

Which method should you choose? If you need a single network without breaks (for example, for smart home or roaming between rooms), use WDS. If it is enough just boost the signal in the far corner of the apartment - will do repeater mode. To connect stationary devices (for example, TV set-top boxes in another room) is optimal client bridge.

2. Preparing for setup: what you need to do BEFORE connecting the routers

Before linking routers, complete the following mandatory preparatory steps. Ignoring them will result in the devices either not being able to see each other or an unstable connection.

Update the firmware on both routers|Write down the MAC addresses of the devices|Check Wi-Fi compatibility (802.11n/ac/ax)|Configure static IP addresses to avoid conflicts|Disable DHCP on the second router (if using WDS or client bridging)-->

1. Update the firmware on both routers. Outdated software versions may not support the modes. WDS or RepeaterFor example, in routers TP-Link Archer C6 up to firmware version 1.2.0 there was no support 802.11r (fast roaming), which led to connection breaks when switching between points.

2. Check Wi-Fi standards compatibilityIf the first router only works in the standard 802.11n (maximum 300 Mbps), and the second one supports 802.11ac (up to 1.3 Gbps), the connection speed will be limited by the slowest device. Optimally, both routers should support at least 802.11ac (Wi-Fi 5).

⚠️ Attention: If one of your routers is older than 2015, check its specifications on the manufacturer's website. Devices that support only 802.11g (54 Mbps) will not be able to provide a stable connection for modern tasks (for example, streaming 4K video).

3. Record MAC addresses both routers. They will be needed for configuration. WDS or device filtering. Find them on the sticker on the device or in the web interface under Status/State.

3. Method 1: Connecting routers via WDS (single network)

Mode WDS (Wireless Distribution System) allows you to create a single wireless network from multiple routers. All devices will connect to it automatically, switching between access points depending on the signal strength. This method is ideal for smart homes where devices (e.g., Xiaomi lamps or robot vacuum cleaner) must remain on the same network.

However, WDS There are two critical drawbacks: 1) Connection speed drops by 30-50% due to double traffic encryption (data is encrypted on the first router, decrypted on the second, and encrypted again for the client). 2) Not all routers support WDS in mode 802.11ac - often only works 802.11n (maximum 300 Mbps).

Step-by-step WDS setup using the TP-Link Archer C6

Step 1. Connect to the main router (the one that distributes the Internet) and go to the web interface (usually at 192.168.1.1 or 192.168.0.1).

Step 2. In the section Wireless → Wireless Settings:

• Write it down channel (For example, 6 For 2.4 GHz).
• Enable the option Enable WDS.
• Click Search and select the second router from the list (if it is already turned on).

Step 3. Go to the second router and in its settings:

• Turn it off DHCP (in the section Network → DHCP).
• IN Wireless Mode → WDS Settings please indicate MAC address main router.
• Install the same one channel And security mode (For example, WPA2-PSK).
• In the field SSID Enter the same network name as on the main router.

Step 4. Save the settings on both devices and reboot them. After this, both routers should create a single network.

⚠️ Attention: If after setting up the devices they cannot connect to the network, check that the second router is disabled DHCP and static is installed IP address from the subnet of the main router (for example, 192.168.1.2, if the main one has 192.168.1.1).

4. Method 2: Repeater mode - a simple signal amplifier

If you don't need a single network, but just want to boost the Wi-Fi signal in a remote room, the mode repeater (Repeater) is the simplest solution. In this case, the second router connects to the main one via Wi-Fi and rebroadcasts its signal, creating a new network (for example, MyWiFi_EXT).

Advantages of the method:

✅ Setup takes 5-10 minutes.

✅ No channel matching or disconnection required DHCP.

✅ Supported by almost all modern routers.

Flaws:

❌ Devices don't automatically switch between routers—you need to manually select a network.

❌ Speed ​​may drop by 20-40% due to retransmission.

Setting up repeater mode on the ASUS RT-N12

Step 1. Connect to the second router (the one that will be the repeater) and go to its web interface.

Step 2. In the section Administration → Operating Mode select Repeater Mode.

Step 3. Click Search and select your primary network from the list. Enter its password.

Step 4. Think of a name for the new network (for example, MyWiFi_EXT) and set a password. Save the settings.

After rebooting, the second router will begin rebroadcasting the signal. Connect to the new network and test the speed using the service Speedtest.

Why does the speed drop in repeater mode?

When retransmitting a signal, data is transmitted twice: first from the primary router to the repeater, then from the repeater to the device. This increases latency (ping) and reduces throughput. Furthermore, the repeater takes up bandwidth to service the connection, further reducing available speed.

5. Method 3: Client bridge - for connecting devices via cable

If you need to connect a stationary device (for example, Smart TV, gaming console or PC) in a room with a weak Wi-Fi signal, client bridge (Client Mode) is the optimal solution. In this mode, the second router connects to the main one via Wi-Fi and then distributes the internet via cable (LAN) or your own Wi-Fi.

Advantages:

✅ Stable connection for devices that require high speed (eg. 4K streaming or online games).

✅ No speed loss, as in repeater mode.

Flaws:

❌ Requires static configuration IP addresses.

❌ Not all routers support this mode out of the box (alternative firmware may be required, for example, DD-WRT).

Setting up a client bridge on Keenetic

Step 1. Connect to the second router (Keenetic) and go to the web interface.

Step 2. In the section Internet → Connections click Add connection and select Wireless connection (WISP).

Step 3. In the connection settings:

• Please enter the name of the primary network (SSID).
• Select the security type and enter the password.
• In the section IP address install Receive automatically or specify static IP from the main router's subnet.

Step 4. Save the settings and connect the device (for example, TV) To Keenetic via cable (LAN).

6. Common mistakes and their solutions

Even with proper configuration, the connection between routers may be unstable. Here top 5 mistakes and ways to eliminate them:

• 🔌 The routers don't see each other.:

  Check that both devices are operating in the same band (2.4 GHz or 5 GHz). If one router only supports 2.4 GHz, and the second one is set to 5 GHz, they won't be able to connect. Also, make sure the channels don't overlap (e.g. 1 And 6 on 2.4 GHz do not conflict).

• 🐢 Speed ​​drops by 50% or less:

  This is normal for modes WDS And RepeaterTo reduce losses, use a range 5 GHz (if both routers support it) and set a fixed channel with minimal interference (check through the app Wi-Fi Analyzer).

• 🔄 Devices do not switch between routers automatically:

  In mode WDS check that the network names (SSID) and the passwords on both routers match. If used Repeater, there will be no automatic switching - this is normal.

• 🚫 No internet access:

  Make sure that the second router is disabled. DHCP (if used WDS or Client Mode). Also check that the main router is distributing IP addresses in the correct range (for example, 192.168.1.100-200).

• 🔒 Constantly asks for a password:

  This happens if the security types (WPA2/WPA3) or encryption (AES/TKIP) on the routers do not match. Set the same parameters in the sections Wireless Network → Security.

⚠️ Attention: If you use routers from different manufacturers (for example, TP-Link And ASUS), check their compatibility in mode WDSSome models (especially budget ones) support this mode only with devices of the same brand.

7. How to check the connection quality between routers

After setting up the router bundle, you need to evaluate the stability and speed of the connection. Here 3 diagnostic methods:

• 📊 Ping between routers:

  Connect to any router via SSH (if supported) and run the command:

  ping 192.168.1.1

  If packet loss (>5%) or latency (>50 ms) is high, the connection is unstable. Try changing the channel or reducing the distance between the routers.

• 📈 Speed ​​test:

  Connect the device to each router separately and run the test Speedtest.netThe speed difference shouldn't exceed 30%. If the drop is greater, check your settings. WDS or Repeater.

• 🔍 Signal analysis:

  Use apps like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) to check the signal strength (dBm) at different points of the room. Optimal value: from -50 dBm (excellent) to -70 dBm (acceptable).

If your connection is unstable, try the following:

1. Reduce the distance between routers or install them so that there are a minimum number of obstacles (walls, furniture) between them.
2. Change your Wi-Fi channel to a less busy one (use Wi-Fi Analyzer for ether analysis).
3. Update the firmware on both routers to the latest version.
4. If you use 2.4 GHz, try switching to 5 GHz (if both routers support this range).

8. Alternative Solutions: When Wi-Fi Bridge Isn't Suitable

If after all attempts the connection between the routers remains unstable, consider alternative options:

• 🔌 Powerline adapters:

  Use electrical wiring to transmit the internet signal. Speed ​​up to 1 Gbps, but it depends on the quality of the wiring. This is suitable for situations where the routers are located in different rooms, but running cables is not possible.

• 📡 Access points (AP):

  If the second router supports the mode Access Point (AP), connect it to the main one via cable LANThis will provide maximum speed and stability without the losses typical of a Wi-Fi bridge.

• 📶 Mesh systems:

  Ready-made solutions like TP-Link Deco or Google Nest Wi-Fi They create a unified network with automatic switching between nodes. They're more expensive, but easier to set up and more reliable than homemade router bundles.

If you still want to use Wi-Fi Bridge but are experiencing issues, try alternative firmware like DD-WRT or OpenWRTThey support advanced settings. WDS And 802.11r (fast roaming), which can solve problems with switching between points.

⚠️ Attention: Installing alternative firmware may void your router's warranty and cause it to malfunction due to a firmware error. Before installing, check the model's compatibility on the official website. DD-WRT or OpenWRT.

FAQ: Answers to Frequently Asked Questions

Is it possible to connect routers from different manufacturers (for example, TP-Link and ASUS)?

Yes, but with reservations. In the mode Repeater or Client Mode problems usually don't arise. However WDS may work unstably if routers use different implementations of this standard. For example, TP-Link And ASUS Sometimes conflicts occur due to differences in encryption. In such cases, manually configuring the channel and security type helps (WPA2-AES).

Why did my internet speed drop by half after setting up WDS?

This is a normal phenomenon for WDS, since data is transmitted twice: from the main router to the secondary one and then to the device. To reduce losses:

• Use range 5 GHz (if supported).
• Establish a fixed channel with minimal interference.
• Disable unnecessary features like QoS or Parental Control on the second router.

If speed is critical, consider a wired connection or Powerline adapters.

How can I make devices automatically switch between routers?

For automatic switching (roaming) you need:

• Use identical SSID, password and security type on both routers.
• Tune WDS or mode Mesh (if supported).
• Set different channels for routers (for example, 1 And 6 on 2.4 GHz), so that they do not interfere with each other.
• Enable support 802.11r (fast roaming), if the routers support it.

Please note that not all devices (especially older smartphones) work correctly with roaming. In this case, you'll have to switch manually.

Is it possible to use three or more routers in one network?

Yes, but with each new access point, speed and stability will decrease. Optimal setup for 3+ routers:

• The main router is connected to the Internet.
• The second router is connected to the first one via cable (LAN) in mode AP.
• The third router is connected to the second one WDS or Repeater.

Avoid chains of more than 2 wireless connections (e.g. router 1 → router 2 → router 3), as this will critically reduce speed.

How do I reset my router if it stops working after setting up WDS?

If the router becomes unavailable after setup, perform a factory reset:

1. Find the button on the router body Reset (usually recessed into the body).
2. Press it with a pin or paper clip and hold it 10-15 seconds.
3. After rebooting, the router will return to factory settings (usually IP: 192.168.1.1, login/password: admin/admin).

If resetting doesn't help, check to see if the router is damaged (for example, after a power surge). In this case, it will need repair or replacement.
