Configuring a Router to Receive Wi-Fi from Another Router: 3 Working Methods

Do you want to extend the Wi-Fi coverage in your home or office, but can't run a cable from your main router? The solution is simple: configure a second router so that it received a signal from the first and retransmitted This will eliminate "dead zones" where the internet connection drops, or allow you to connect devices in a remote room without running network cables.

However, not everyone knows that there is a solution for this task three different operating modes: repeater, bridge And WDSEach of these methods has its own nuances, advantages, and limitations. For example, in repeater mode, connection speeds can drop by half, and when setting up WDS, you'll need to maintain the same security standards on both devices. In this article, we'll cover all connection methods and provide step-by-step instructions for popular router models (TP-Link, ASUS, Keenetic, MikroTik) and we’ll tell you how to avoid typical mistakes.

Before you begin setup, make sure both routers support the desired mode. Older models (manufactured before 2015) often lack WDS functionality or repeater mode. Also, check that the Wi-Fi standards match: if the primary router only operates within the range 2.4 GHz, and the second one supports 5 GHz, the setup may not work.

1. Router-to-router connection methods: which one to choose?

There are three main methods for establishing Wi-Fi connections between routers. They differ in their operating principles, data transfer speeds, and setup complexity.

• 🔄 Repeater mode — the second router connects to the first one’s network as a client and relays it with the same name (SSID) or others. It's the easiest to set up, but the speed drops by 30-50% due to double data transfer.
• 🌉 Bridge Mode — The routers are connected via Wi-Fi or cable, but the second one operates as a "transparent" node, without creating a separate network. This is suitable for connecting devices via cable (such as a Smart TV or PC) in a remote room.
• 📶 WDS (Wireless Distribution System) — an advanced bridge option where both routers exchange data via Wi-Fi without speed loss (if configured correctly). Requires compatibility of security standards and channels.

Which method should you choose? If you just need boost Wi-Fi signal in the back room - will do repeaterIf you need to connect wired devices (for example, a game console) - set up bridge. For maximum speed and stability (for example, for an office) it is optimal WDS, but it is the most difficult to set up.

⚠️ Note: Some routers (eg. Keenetic or MikroTik) support the regime Mesh networks, which automatically selects the best channel and data transmission route. If your devices are Mesh-compatible, use it instead of WDS—it will simplify setup and improve stability.

2. Preparing for setup: what you need to do before you start

Before connecting routers, complete a few mandatory steps. This will save time and help avoid errors.

Reset the second router to factory settings (button Reset)

Connect the second router to the PC via cable (for initial setup)

To know SSID and the password for the main Wi-Fi network

Check the supported Wi-Fi standards on both routers (802.11n/ac/ax)

Update firmware on both devices (if updates are available)-->

Pay special attention Wi-Fi channelsIf the main router is operating on the channel 13, and the second one doesn't support that channel (for example, in the US, only channels 1–11 are allowed), the connection won't be established. Check the channel settings in the main router's web interface (section Wireless or Wireless network).

Also make sure that on the second router DHCP server is disabled (if it's operating in bridge or WDS mode). Otherwise, IP address conflicts may occur, and devices will be unable to connect to the network. The exception is repeater mode, where DHCP can remain enabled.

⚠️ Attention: If you are setting up a router ASUS or TP-Link in repeater mode, some models automatically change MAC address Wi-Fi adapter. This may result in blocking by the main router (if MAC binding is enabled). Disable this feature in the security settings of the main device.

3. Configuring the router in repeater mode

This is the easiest way to extend Wi-Fi coverage. The second router connects to the first router's network and rebroadcasts it, possibly under a different name (SSID). The downside is that the connection speed is reduced by approximately 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 a router as 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 → System tools → Operating mode.
3. Select Wi-Fi Booster (or Range Extender) and press Save.
4. After rebooting, the router will prompt you to select a network to replicate. Specify SSID main router and enter the password.
5. Set up a name for the new network (you can leave it the same as the main router, or add a suffix, for example _EXT).
6. Save the settings and wait for the reboot.

For routers ASUS (For example, RT-AX55) the path will be different:

Wireless Network → Operation Mode → Repeater
→ Select network → Enter password → Apply

After setup, disconnect the cable and check if the new Wi-Fi network appears. Connect to it and test the speed (for example, via Speedtest). If the speed has dropped by more than 50%, try changing the channel on your main router or reducing the transmission power.

4. Configuring the router in Bridge mode

Bridge mode is suitable if you need to connect to a remote router wired devices (for example, a Smart TV, game console, or computer). In this case, the second router doesn't create a separate Wi-Fi network, but simply "transparently" transmits data from the main router via a cable.

For example, if you have a primary router in the living room and a secondary router in the bedroom, connected to a TV via a cable, setting up a bridge will allow the TV to receive internet as if it were directly connected to the primary router.

Instructions for the router Keenetic:

1. Connect the second router to your PC via cable and log in to the web interface (192.168.1.1).
2. Go to Internet → Wi-Fi connection.
3. Click Add connection and select Client (Bridge).
4. From the list of available networks, select SSID main router and enter the password.
5. In the section Local area network turn it off DHCP server (to avoid IP conflicts).
6. Save the settings and connect the devices to the router via cable.

For routers MikroTik (For example, hAP ac²) the setup is more complicated and requires knowledge Winbox:

/interface wireless
set [ find default-name=wlan1 ] master-interface=wlan2 mode=station \
ssid="Primary_Network_Name" security-profile=default

/ip dhcp-client add interface=wlan1

After setting up, check if the device connected via cable is receiving IP address from the main router. If not, check whether DHCP is disabled on the second router and whether the settings are correct. VLAN (if the main router uses traffic tagging).

⚠️ Note: In bridge mode, the second router does not create its own Wi-Fi network. If you need both wired and wireless connections, use bridge mode. WDS or set up a repeater.

5. WDS Setup: Maximum Speed ​​Without Losses

WDS (Wireless Distribution System) — is the most efficient way to connect routers via Wi-Fi, as it allows data exchange without double encryption and speed loss. However, for this to work, both routers must support WDS and use the same security settings.

Basic requirements for WDS:

• 🔒 Same safety standard (For example, WPA2-PSK)
• 📡 Same Wi-Fi channel (For example, 6)
• 📋 Same operating mode (802.11n, 802.11ac)
• 🔄 WDS support on both routers

Instructions for the router TP-Link TL-WR841N:

1. Log into the web interface of the second router and go to Wireless → WDS.
2. Click Survey (Search) and select the network of the main router. Click Connect.
3. In the field SSID Enter the same network name as on the main router (or another one if you want to separate the networks).
4. In the section Wireless Security Select the encryption type and enter the password (must match the main router).
5. In the section DHCP turn off the server (Disable).
6. Save the settings and reboot the router.

For routers ASUS (For example, RT-AC66U):

Wireless Network → Bridge → Enable WDS
→ Select network → Enter password → Apply

After setup, check that both routers can see each other. To do this, look in the list of connected devices on the main router—it should appear there. MAC address second router.

6. Common mistakes and their solutions

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

If after setup the second router periodically turns off, check signal strengthIf the signal level is lower -70 dBm, the connection will be unstable. In this case:

• 📶 Move the second router closer to the main one.
• 🔄 Change the channel to a less busy one (use utilities like Wi-Fi Analyzer for ether analysis).
• 📡 Replace the antennas with more powerful ones (if the router supports removable antennas).

7. Alternative ways to expand your Wi-Fi network

If setting up your router in repeater, bridge, or WDS mode seems complicated, consider these alternatives:

• 📡 Special repeaters - compact devices like TP-Link RE605X or ASUS RP-AX56, which simply plug into a power outlet and repeat the signal. They don't require complicated setup.
• 🔌 Powerline adapters — transmit the Internet through electrical wiring (for example, TP-Link TL-PA7010P). Suitable if the routers are far from each other, but there is a common power grid.
• 🌐 Mesh systems — a set of several nodes (for example, Google Nest Wi-Fi or ASUS ZenWiFi), which automatically adjust to optimal coverage.

The advantage of specialized repeaters is the ease of setup (just press a button WPS (on the main router and the repeater). However, they are usually more expensive than using a second router in repeater mode.

Powerline adapters are convenient if the routers are in different rooms but connected to the same power grid. Speed ​​depends on the quality of the wiring and can reach 1 Gbps (under ideal conditions). Mesh systems are the most modern solution, but also the most expensive.
