How to connect two routers into one Wi-Fi network wirelessly

Connecting two routers into a single Wi-Fi network is a challenge faced by owners of large apartments, private homes, or offices. Weak signal strength in remote rooms or the need to expand the number of connected devices forces people to seek solutions without running cables. But how can you properly connect equipment to maintain speed and avoid IP address conflicts?

Many users mistakenly believe that simply placing a second router next to the first one will automatically expand the network. In practice, this leads to the creation of two isolated networks, between which the devices cannot see each other. Proper pairing requires setting up special modes: WDS bridge, repeater mode or client bridgeThe choice of method depends on the router models, their supported features, and your goals—whether you need to expand your coverage area or simply add ports for wired devices.

In this article, we will analyze all the working connection methods and discuss in detail the settings of popular brands (TP-Link, ASUS, Keenetic, MikroTik), and we'll also tell you how to avoid common errors that can cause the network to become unstable or not connect at all.

1. When should you connect two routers via Wi-Fi?

Wirelessly connecting routers is useful in several scenarios:

• 📶 Weak Wi-Fi signal In remote rooms, the second router acts as an amplifier, expanding the coverage area without laying cables.
• 🖥️ Lack of ports — if you need to connect several wired devices (PC, printer, Smart TV) to the main router, but all LAN ports are occupied.
• 🏠 Multi-story building or large office — one router physically cannot cover the entire area, and laying cables between floors is expensive or impossible.
• 🔄 Channel reservation — the second router can act as a backup gateway if the main one fails (relevant for businesses).

However, the wireless connection of routers also has restrictions:

• ⚡ Loss of speed — when using the repeater mode, the actual speed may drop by 30–50% due to double data transfer (router → repeater → device).
• 🔗 Dependence on the main router - if it reboots or fails, the second router will also lose connection.
• 📡 Interference - if the routers operate on the same frequency (for example, both on 2.4 GHz), they can create mutual interference.

If maximum speed is critical to you (for example, for 4K video streaming or online gaming), consider linking routers together. via cable (LAN-to-LAN) or via Powerline adapters (via electrical wiring). Wireless connection is suitable for everyday tasks: surfing the Internet, working with documents, or watching videos in 1080p.

2. Methods for connecting two routers via Wi-Fi

There are three main methods for connecting routers to a single Wi-Fi network. Each has its own characteristics, pros, and cons:

Which method should I choose?

• 🔄 If you need one network with automatic switching between routers (roaming), use WDS.
• 📶 If the task is simple boost the signal in a remote room, will do repeater mode.
• 🖥️ If needed connect wired devices (PC, printer) in another room, set up client bridge.

⚠️ Attention: Some routers (eg. Keenetic or ASUS with Merlin firmware) support the mode Mesh networks, which allows you to connect devices into a single network with roaming without losing speed. If your routers support Mesh, use it instead of WDS.

3. Preparing for setup: what you need to do before connecting

Before you begin setting up, please complete a few mandatory steps:

Reset the second router to factory settings | Check compatibility of modes (WDS/Bridge) | Fix the IP addresses of the primary and secondary routers | Select the optimal Wi-Fi channel for communication between the routers | Update the firmware on both devices (if updates are available) -->

1. Reset the second router

If the second router has already been used, Be sure to reset its settings to factory settings. This will avoid conflicts with previous settings. To reset:

• Find the button on the back panel Reset (usually recessed into the body).
• Press it with a paper clip or toothpick and hold it 10-15 seconds.
• Wait for the reboot (the indicators should flash).

2. Checking compatibility

Not all routers can work together in WDS or bridge mode. For example:

• 🔴 Routers from different manufacturers (For example, TP-Link And ASUS) may not connect due to different WDS implementations.
• 🟢 Routers of the same brand (for example, two Keenetic) are usually compatible.
• ⚠️ Old models (released before 2015) may not support modern standards 802.11ac/ax.

3. IP address fixation

To avoid conflicts, decide on IP addresses in advance:

• Main router: usually 192.168.1.1 or 192.168.0.1.
• Second router: must have an address from the same subnet, but with a different last digit (for example, 192.168.1.2).

4. Selecting a Wi-Fi channel

For a stable connection between routers, select less congested channel in the range 2.4 GHz or 5 GHzUse apps like Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) for broadcast analysis.

⚠️ Attention: If you are setting up a connection on a frequency 5 GHz, make sure both routers support the same standard (802.11ac or 802.11ax). Otherwise, the speed will drop to 802.11n (maximum 300 Mbps).

4. Setting up a connection in WDS mode (using TP-Link and ASUS as examples)

Mode WDS (Wireless Distribution System) allows you to combine two routers into one network with a common SSID and automatic switching between them (if devices support roaming). Let's look at the setup using popular brands as examples.

Step 1: Setting up the main router

1. Connect to the main router via cable or Wi-Fi.

2. Go to the control panel (usually at 192.168.1.1 or 192.168.0.1).

3. Find the section in the menu Wireless mode → Wireless settings.

4. Remember or write down:

• Network Name (SSID)
• Channel (Channel)
• Security type (WPA2-PSK or WPA3)
• Password

5. Enable the option Enable WDS (if any) or Allow other devices to connect in bridge mode.

Step 2. Setting up a second router (TP-Link)

1. Connect to the second router and log into its control panel.

2. Go to Wireless Mode → WDS Settings.

3. Click Search and select the main router network.

4. In the field Security type Specify the same one as on the main router.

5. Enter the password for the main network.

6. In the section LAN change the IP address of the second router (for example, to 192.168.1.2) to avoid conflict with the main (192.168.1.1).

7. Disable the DHCP server on the second router (section DHCP → DHCP Settings → Disable).

8. Save the settings and reboot both routers.

Step 3. Setting up the second router (ASUS)

1. In the control panel, go to Wireless Network → Bridge.

2. Select the mode AP Mode (access point) or Repeater Mode (repeater) if WDS is not supported.

3. In the section Wireless Network → General indicate the same SSID, channel and security type, as on the main router.

4. In LAN → DHCP server Turn off the server.

5. Save the settings.

What to do if routers cannot see each other in WDS?

If the second router does not find the main router's network in WDS mode, check:

1. Do the Wi-Fi standards match (for example, both must support 802.11n or 802.11ac).

2. Is the channel specified correctly (not Auto, and fixed, for example, 6 or 11).

3. Is there any interference from other networks (use Wi-Fi analysis apps).

4. Are the firmware updates on both devices?

If the problem persists, try using the mode repeater instead of WDS.

Step 4: Checking the connection

After reboot:

• Connect to a Wi-Fi network (the name must match the main router).
• Check that the Internet is working.
• Make sure that the devices can "see" each other on the local network (for example, you can access the 192.168.1.1 And 192.168.1.2).

5. Setting up Repeater mode

If your router does not support WDS or you just want to boost the signal without complex settings, use the mode repeaterIn this case, the second router will relay the network of the main one, but with a different SSID (if roaming is not configured).

Instructions for TP-Link routers:

1. Connect to the second router and log into the control panel.

2. Go to Wireless Mode → Repeater Settings.

3. Click Search and select the main router network.

4. Enter the password for the main network.

5. In the section LAN change the IP address of the second router (for example, 192.168.1.3).

6. Disable the DHCP server.

7. Save the settings and reboot the router.

Instructions for ASUS routers:

1. In the Control Panel, select Wireless Network → Operating Mode.

2. Install Repeater Mode.

3. Select the main router network from the list and enter the password.

4. Disable DHCP in the section Local Area Network (LAN) → DHCP Server.

5. Save the settings.

Repeater mode features:

• 🔄 If roaming is not configured, devices will have to manually reconnect between networks.
• 📶 The internet speed on devices connected to the extender will be lower than on the main router.
• 🔌 In repeater mode, the LAN ports of the second router usually do not work (unless an additional bridge is configured).

⚠️ Attention: Some routers (eg. Keenetic) in repeater mode, Wi-Fi sharing is automatically disabled according to a schedule if there are no connected devices. To avoid this, disable the function Energy saving in the settings.

6. Configuring the Client Bridge

Mode Client Bridge Allows you to connect a second router to the main one via Wi-Fi, and then distribute the internet via a cable (LAN) to wired devices. This is useful if you need to connect, for example, Smart TV, game console or PC in another room without cable laying.

Instructions for routers based on DD-WRT (for example, reflashed TP-Link):

1. Connect to the second router and log into the control panel.

2. Go to Wireless → Basic Settings.

3. Install Wireless Mode: Client Bridge.

4. In Wireless Network Name (SSID) Specify the name of the primary network.

5. In Wireless Security Select the encryption type and enter the password.

6. In the section Setup → Network Setup Disable the DHCP server.

7. In Setup → LAN change the IP address of the second router (for example, 192.168.1.4).

8. Save the settings and reboot the router.

Instructions for MikroTik routers:

1. Connect to the router via WinBox.

2. Go to Wireless → Security Profiles and create a profile with the main network parameters.

3. In Wireless → Interfaces set up Mode: station-pseudobridge.

4. In IP → DHCP Client Add a client to receive IP from the main router.

5. In IP → Firewall → NAT Set up masquerading for your local network.

6. Disable the DHCP server on the second router.

Checking the work:

• Connect the device (PC, TV) via cable to the LAN port of the second router.
• Make sure the internet is working and the device is receiving an IP address from the main router.

In Client Bridge mode, the second router doesn't distribute Wi-Fi—it only forwards internet to wired devices. If you also need a wireless network, set up an additional access point on a different channel.

7. Common mistakes and their solutions

When setting up a Wi-Fi connection between two routers, users often encounter problems. Let's look at the most common ones and how to fix them:

Additional tips:

• 🔄 If the speed is critically low, try using the range 5 GHz (if the routers support it).
• 📡 If the routers are far from each other, use directional antennas or signal amplifiers.
• 🔧 If the settings are lost after a reboot, update the firmware on both devices.

⚠️ Attention: If you use routers with firmware from an Internet provider (for example, Rostelecom or Beeline), some features (such as WDS) may be blocked. In this case, contact your provider's support or upgrade your router to a third-party firmware (e.g., DD-WRT or OpenWRT).

8. FAQ: Frequently asked questions about connecting routers

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

Yes, but only if both routers support it. the same connection mode (WDS, Repeater or Bridge). For example, TP-Link And ASUS can work together in WDS mode if:

• Both support the standard 802.11n/ac.
• The same channel and encryption type are used.
• The main router allows other devices to connect in bridge mode.

If the routers don't see each other, try the mode repeater or update the firmware.

How can I make devices automatically switch between routers?

To automatically switch (roam) between routers, you need to:

• Tune the same SSID, password, and security type on both routers.
• Use different channels (for example, the main router on the channel 1, the second one is on 6 or 11 For 2.4 GHz).
• Enable support for the standard 802.11r (Fast Transition), if the routers support it (available on ASUS, Keenetic, Ubiquiti).

If routers do not support roaming, devices will have to reconnect manually.

Why did my internet speed drop by half after connecting my routers?

This is a normal phenomenon when using wireless bridge (WDS or Repeater)Data is transmitted along the chain: Primary router → Secondary router → Your device, which increases latency and reduces throughput.

To reduce losses:

• Use range 5 GHz (if supported).
• Place the routers as close to each other as possible.
• Disable unnecessary features (eg. QoS or Parental Control), which can put additional load on the processor.

If speed is critical, consider connecting routers together. via cable.

Is it possible to use a second router as a signal booster and simultaneously connect devices to it via cable?

Yes, but to do this you need to set up the operating mode correctly:

• In mode WDS or Repeater Usually only wireless clients work. To use LAN ports, configure Client Bridge or turn on the mode AP Mode (access point) on the second router.
• On some routers (for example, ASUS) in mode Media Bridge You can simultaneously retransmit Wi-Fi and distribute Internet via cable.

Please check the documentation for your router model to determine which modes are supported.

How do I reset my router if I forgot my password?

To reset your router to factory settings:

1. Find the button on the back panel Reset (usually recessed into the body).
2. Press and hold it 10-15 seconds (until the indicators start flashing).
3. Release the button and wait for the reboot (1-2 minutes).
4. Connect to the router via cable or Wi-Fi (the network name and password will be the default ones, indicated on the sticker).

After resetting, all settings (including Wi-Fi password and WDS settings) will be deleted.
