It's common for the signal from the main router to be too weak in one room of a home or remote office, making it impossible to install a new cable. In such cases, an old or secondary ASUS router can be an ideal solution for expanding the network without purchasing expensive specialized equipment. Converting the router into a receiver not only boosts the signal but also connects wired devices, such as Smart TVs or gaming consoles, to the internet in areas without a LAN outlet.
Reconfiguring the device requires careful attention to interface settings, as the router's default operating mode won't work. You'll need to change the IP address distribution logic and switch the physical ports to bridge mode. It is important to understand, that not all models support the same set of functions, so before you start working, you should make sure that your device Asus RT-N12, RT-AC51U or a more powerful series RT-AX the necessary hardware base.
In this article, we'll cover two main use cases in detail: Client mode for connecting a single device via cable and Repeater mode for expanding wireless coverage. Each method has its own advantages and limitations, which we'll discuss below. Proper configuration will allow you to create a single, seamless network or an isolated segment for guest access.
Selecting the appropriate router operating mode
Before you begin setting up the device, you need to clearly define what task the second device should perform. Firmware interface AsusWRT offers several options, but two are generally suitable for signal reception. Confusion over terminology often leads users to select the wrong mode and not achieve the desired result.
The first option is the mode Media Bridge or "Bridge Mode." In this scenario, the ASUS router receives the Wi-Fi signal from the main access point and broadcasts it only to its LAN ports. The ASUS router's wireless module is typically disabled or receives only in this mode, without creating a new access point for phones and laptops. This is ideal for connecting a desktop computer or TV.
The second option is the regime Repeater (Repeater) or ExtenderHere, the device receives the signal, amplifies it, and distributes it further, creating a new Wi-Fi coverage area. Client devices can connect to either the main router or the ASUS device. Asus implements this function through AiMesh technology or classic repeater mode, depending on the model.
⚠️ Note: On older router models, client mode may be called "Client" or "Wireless Bridge." Make sure you don't confuse this with "Access Point" mode, which requires a cable connection from the main router.
The choice between these modes depends on your ultimate goal. If you simply need to extend the internet connection to the next room for one device via a wire, choose the bridge mode. If you want Wi-Fi coverage throughout your entire home, including far corners, you need the repeater mode.
Preparing for setup and resetting settings
Any major reconfiguration of network equipment should start with a clean slate. Using old settings left over from a previous provider or configuration can cause IP address conflicts and network instability. Therefore, a hard reset should always be the first step.
To perform a reset, locate the button on the back of the device. Reset or WPS/ResetWith the router turned on, press and hold this button with a thin object (such as a paperclip) for 10-15 seconds until the indicators flash simultaneously. After this, the device will reboot to factory settings.
☑️ Equipment preparation
After the reset, connect your computer to the ASUS router using an Ethernet cable by plugging it into any yellow LAN port. The computer should automatically obtain an IP address. Open your browser and enter [IP address] in the address bar. 192.168.1.1 or router.asus.comYou will be taken to the quick setup wizard.
At this stage, it's important not to connect the ASUS router to the internet or the main router via cable. All settings are performed in isolated mode. If the setup wizard immediately prompts you to select a connection type (PPPoE, Dynamic IP), select "Skip" or "Manual Setup" to access the full menu.
Setting up Media Bridge mode (Client)
Media Bridge mode is the most stable way to connect devices via cable in areas where a cable from the main router isn't possible. In this mode, your ASUS becomes a network card with antennas. Configuration is performed through the web interface in the section Administration -> Opening hours.
Select an item Bridge mode (Media Bridge) and click "Save." The router will reboot. After the reboot, the interface may become unavailable at 192.168.1.1, as the IP address is now assigned by the main router. To find the device, use the utility Operation Mode or look at the list of clients in the main router.
| Parameter | Meaning / Action | Note |
|---|---|---|
| Opening hours | Media Bridge | Broadcast Wi-Fi to LAN |
| WAN port | Not used | Becomes part of the LAN |
| Wi-Fi module | Works for reception | Wi-Fi sharing is disabled |
| IP address | Issued by the main router | You need to look in the DHCP list |
Next, you need to connect your device to a Wi-Fi network. In the settings interface, go to the section Wireless networkHere you'll see a list of available networks. Select your primary network, enter the password, and click "Connect." Once successfully connected, the WAN indicator (or the corresponding connection indicator) should light up.
What to do if the IP address has changed?
If you can't access your router settings after switching to bridge mode, use the cmd command: ipconfig (on Windows) or view the list of connected clients on the main router. Find the device by the MAC address listed on the sticker on the bottom of the ASUS router and use its IP address to log in.
Now, any cable connected to the ASUS router's LAN port will have internet access via the main router's Wi-Fi channel. This is an excellent solution for connecting Smart TVs where the built-in Wi-Fi module is slow or unstable.
Using Repeater Mode
If your goal is to increase your wireless network coverage by allowing smartphones and laptops to connect directly to your ASUS router, you need repeater mode. In the ecosystem Asus This is often implemented through AiMesh technology, but the classic Repeater mode is also available in many models.
On the menu Administration -> Opening hours select Repeater mode (Repeater mode). The system will prompt you to search for available wireless networks. Select the SSID of your main router from the list. If the network is hidden, enter the name manually.
The key here is to set the SSID and password. To create seamless roaming (when devices automatically switch between routers), the network name (SSID) and password must match the main router, but the broadcast channels must be different. For example, if the main router broadcasts on channel 1, set the ASUS to 6 or 11.
After applying the settings, the router will reboot and attempt to connect to the primary access point. The indicators on the router will indicate the connection quality. If the red indicator is lit or the blue indicator is flashing, the signal is too weak, and the ASUS router should be moved closer to the signal source.
Setting up AiMesh technology for a smart grid
Owners of modern routers Asus (AC1200 series and above, as well as all AX models) have access to AiMesh technology. This is an advanced version of repeater mode, allowing you to create a single, manageable network from multiple routers. Unlike a classic repeater, AiMesh dynamically selects the best path for traffic.
To set up AiMesh, the main router (the one connected to the internet provider) must be configured as the primary node. The second ASUS router, which will act as a receiver, must be reset and connected to the main router via the AiMesh menu in the main device's interface. The system will automatically select the optimal settings.
The advantage of this method is centralized management. You don't need to access the settings of each device individually. You can view the network topology, connection speeds between nodes, and manage the guest network for all access points at once. However, AiMesh requires firmware version 384 or higher.
⚠️ Note: When mixing routers of different generations (for example, an older AC and a newer AX), the network will operate at the speed of the weakest device in the chain. Speed may be limited by the bandwidth of the older router.
Speed optimization and troubleshooting
Even with proper configuration, the speed in receiver mode may be lower than with a direct cable connection. This is due to losses in wireless data transmission. To minimize losses, use the 5 GHz band for backhaul communication between routers, if possible.
Check if your airwaves are congested with neighboring networks. Use Wi-Fi analyzer apps on your smartphone to find free channels. In the settings Asus in the section Wireless network -> Professionally You can manually set the channel width (20, 40, or 80 MHz). For repeater mode, a 40 MHz channel width in the 5 GHz band is often more stable.
It's also worth disabling unnecessary features on the receiving router, such as parental controls or the built-in torrent client, to free up CPU resources for handling network traffic. Make sure both devices have the latest firmware update from the official website.
Why doesn't the ASUS router see the main router's network?
It's possible that the primary router is only operating in 802.11ax (Wi-Fi 6) mode or is using DFS channels that are not supported by the client. Try temporarily changing the primary router's settings to mixed mode (802.11 b/g/n/ac) and selecting a fixed channel in the lower band (36-48).
Is it possible to connect two ASUS routers with a cable in bridge mode?
Yes, but this won't be a wireless bridge, but rather an Access Point mode. You need to connect the main router's LAN port to the ASUS's WAN port (or LAN-to-LAN if you disable DHCP on the client) and select the appropriate mode in the settings. This will provide maximum speed.
Will my internet speed decrease when using repeater mode?
Yes, speed will inevitably drop, as the radio module operates in half-duplex mode (it both receives and transmits). Losses can range from 30% to 50% of the original speed, especially in the 2.4 GHz band. Using a 5 GHz band or a dedicated backhaul channel minimizes this effect.
