Expanding wireless network coverage is often necessary in large apartments, two-story houses, or offices where the primary device's signal doesn't reach all corners of the room. The optimal solution in this situation is installing an additional router, particularly from a popular brand. Asus, which is renowned for its stable operation and functional software. Connecting two routers allows you to create a unified infrastructure where devices can automatically switch between signal sources or operate in different network segments.
The setup process may seem complicated at first glance, but it relies on understanding the basic principles of routing and proper cable connections. The key point The key here is choosing the right topology: whether you'll be running a cable between devices or connecting them over the air. This affects not only the internet speed in the remote room but also the overall stability of the connection.
In this article, we will examine in detail all the preparation stages, physical connection methods, and the intricacies of setting up the web interface. ASUS WRTYou'll learn how to avoid IP address conflicts, properly configure a DHCP server, and select the optimal wireless channel. Being prepared and paying attention to detail will help you create a powerful network without dead zones.
Preparing equipment and selecting a connection diagram
Before configuring the software, you need to decide on the physical connection method for the devices. There are two main options: a wired connection via Ethernet cable and a wireless connection using WDS technology or repeater mode. The wired method provides maximum speed and stability, as it eliminates packet loss typical of wireless connections.
If you choose the cable option, you'll need a patch cord of sufficient length. It's important to ensure the cable is in good condition and has all eight strands, especially if you're aiming for gigabit speeds. The wireless method is suitable for areas where cable installation isn't feasible, but it requires the primary router to be within range of the secondary device.
⚠️ Attention: When using a wireless bridge (WDS), the resulting Internet speed on client devices of the second router may decrease to 50% of the speed of the main channel due to the peculiarities of half-duplex data transmission.
You also need to prepare the devices themselves. The primary router (the one that distributes the internet from the provider) should already be configured and working correctly. The secondary router AsusIt's advisable to reset the device we'll be connecting to factory settings to avoid conflicts with old configurations. This is done by holding down the button Reset on the back panel for 10-15 seconds.
Setting up an IP address and disabling DHCP on the second router
The most common error when merging networks is an IP address conflict. By default, both routers Asus have the same address, for example, 192.168.1.1If you connect them directly without prior preparation, a conflict will occur and you will lose access to the settings. Therefore, you should configure the secondary router separately, without connecting it to the primary device.
Connect your computer or laptop to the second router via a LAN port (any of the yellow ones) using a patch cord. Open your browser and enter the default IP address, found on the sticker on the bottom of the device, into the address bar. This is usually 192.168.1.1 or router.asus.com. Enter your login and password (by default it is often admin/admin).
After logging into the control panel, go to the section Local Area Network (LAN) -> LAN IP addressHere you need to change the IP address of the secondary router so that it is in the same subnet as the primary router, but not the same. For example, if the primary router has the address 192.168.1.1, ask the second one 192.168.1.2 or 192.168.1.254.
The next critical step is to disable the DHCP server. In the same LAN settings tab, find the item Enable DHCP Server and select No (Disable). This will force all devices connecting to the second router to request IP addresses from the main router, ensuring they are on the same local network and can share files.
☑️ Checking LAN settings
What should I do if I forgot my new IP address?
If you've changed your router's IP address and forgotten it, and you've lost access, the only solution is to perform a factory reset (hard reset) using the button on the router. Afterward, the router will revert to the address indicated on the sticker, and you'll have to re-enter all settings.
Physical connection of routers via LAN cable
Once the software preparation is complete, you can move on to the physical connection. Take an Ethernet cable, one end of which is connected to the main router. Important: on the main router, the cable is inserted into LAN port (usually yellow) and not in WAN (blue) unless we are using router mode.
The other end of the cable is connected to the secondary router. AsusHere we also use any of the ports. LANThe WAN port on the second router in this setup (access point mode) remains free. Traffic between devices will now be transmitted through the LAN ports.
Once connected, the indicators on both devices should light up or blink, indicating a link is established. The computer connected to the second router should now receive an IP address from the main router and have internet access. You can check this by opening any website or running a speed test.
| Parameter | Main router | Secondary router (Asus) | Cable connection |
|---|---|---|---|
| Opening hours | Router | Access point (AP) | - |
| IP address | 192.168.1.1 | 192.168.1.2 | - |
| DHCP Server | Enabled | Disabled | - |
| Connecting the cable | LAN port | LAN port | Twisted pair Cat5e/6 |
This setup turns the second router into a simple switch with Wi-Fi sharing functionality. All devices will be able to see each other, which is convenient for setting up a local network, printing to network printers, or running media servers.
Using Media Bridge or Repeater mode
If cable installation is not possible, a wireless connection can be used. Modern routers Asus support operating modes that allow devices to be connected over the air. In the web interface, this is often referred to as Media Bridge or Repeater modeThe mode selection depends on the specific model and firmware version.
To configure, go to the section Administration -> Opening hours. Select mode Media Bridge (if you need to connect the wired devices of the second router to the network of the first) or Repeater (If you need to expand your Wi-Fi coverage). The system will prompt you to scan for available networks.
In the list of found networks, select the SSID of your primary router. You will be asked to enter the password for the primary Wi-Fi network. After saving the settings, the secondary router will attempt to establish a connection. A successful connection is confirmed by the signal indicator or the status in the web interface.
⚠️ Attention: Firmware interfaces may vary depending on the model. If you don't find an exact match, look for the "Wireless Bridge," "WDS," or "AiMesh" sections for more recent models.
It is worth noting that the regime AiMesh is a more advanced alternative to a standard repeater for compatible Asus models. It allows you to create a single, seamless network with intelligent client switching, but requires both routers to support this technology and have updated firmware.
Setting up a wireless network and selecting a channel
To avoid interference and ensure stable operation, it's important to configure your wireless network settings correctly. If both routers operate in the same frequency range (e.g., 2.4 GHz), their channels should not overlap. Channels 1, 6, and 11 are optimal, separated between devices.
In the wireless network settings (Wireless) Set the network name (SSID) and password. You can make the network name on the second router the same as the first one for convenience, but devices may not always switch between them correctly. Different names (for example, Home_Wifi And Home_Wifi_Ext) provide greater control over the connection.
For the 5 GHz band, channel selection is less critical due to the large number of available frequencies, but in multi-family buildings with high network density, manually selecting a free channel can significantly improve speed. Use mobile Wi-Fi analyzer apps to search for available frequencies.
- 📡 Channel 1, 6, 11 — the best non-overlapping channels for the 2.4 GHz range.
- 🔒 Security - Always use WPA2-Personal or WPA3, avoid the outdated WEP.
- 📶 Signal strength — If the routers are located close to each other, reduce the transmitter power on the second device so that they do not "jam" each other.
Diagnosing problems and checking connections
After completing all the settings, you need to ensure that the network is functioning correctly. First, check whether the devices connected to the second router are receiving IP addresses from the primary router's range. This confirms that DHCP is working correctly and that addresses are being assigned from the primary device.
Run a speed test using a service like Speedtest, connecting first to the primary router and then to the secondary one. Compare the results. With a cable connection, speed loss should be minimal (within the margin of error), while with a wireless bridge, a speed drop of 30-50% is considered normal.
If you can't access the internet, check the connection status in the secondary router's web interface. Make sure the default gateway points to the primary router's address. Also, check whether the primary router's antivirus or firewall is blocking new devices.
If the connection is constantly interrupted, try updating the firmware (Firmware) on both devices to the latest version from the manufacturer's official website. This often fixes compatibility issues and improves the stability of wireless modules.
Is it possible to connect routers from different manufacturers?
Yes, you can. Standard TCP/IP and Ethernet protocols allow you to connect equipment from different brands (for example, TP-Link and Asus) via a LAN cable. However, proprietary technologies like AiMesh or EasyMesh will only work within a single brand's ecosystem or with support for universal standards.
Do I need a special cable to connect routers?
No, any standard Cat5e or higher patch cord will work. Modern network cards and router ports support Auto-MDIX technology, which automatically detects the connection type, so crossover cables are not required.
What should I do if my computer can't see the second router after changing its IP address?
You need to manually assign a static IP address to your computer's network card in the same subnet as the router's new address. For example, if the router's address is now 192.168.1.2, assign your computer 192.168.1.5. After configuration, reset the network settings to "Obtain automatically."
