The problem of internet loss in distant rooms or on the balcony is familiar to many owners of apartments with complex layouts. Often, the solution lies not in purchasing expensive new equipment, but in properly configuring the existing one. Using an old router as a repeater allows you to significantly expand your wireless network coverage without incurring additional costs.
Modern technologies make it possible to transform almost any device with support WDS or client mode into a powerful repeater. This is especially important for those who don't want to run long cables through their entire apartment or house. Proper setup will ensure a stable connection in areas where previously only one bar of signal was detectable.
In this guide, we'll cover the technical nuances of equipment reconfiguration, frequency selection considerations, and troubleshooting common errors. You'll learn how to avoid IP address conflicts and set up seamless roaming between devices. This will allow you to create a unified network with high-quality signal throughout your home.
Selecting the right equipment and checking compatibility
The first step is to evaluate the technical specifications of your secondary router. Not every device can operate as a repeater or access point out of the box. Models from TP-Link, Asus, Keenetic And MicroTikIt's important to ensure your device's firmware is up-to-date, as older versions of the software may not support the required mode or may not function correctly.
Pay attention to wireless standards. If your main router distributes internet according to a standard 802.11ac (Wi-Fi 5), using an older device that only supports 802.11n will become a bottleneck. The speed of clients connected to the extender will be limited by the capabilities of the weaker link. Ideally, both devices should support the 5 GHz band, which is less congested and provides better throughput.
⚠️ Note: Some providers have restrictions on using their own equipment in bridge mode. If you're using a fiber optic terminal from your provider, make sure it doesn't block MAC addresses of third-party devices.
It's also worth checking the availability of LAN ports. For setup, you'll need at least one free port to connect a cable during the initial configuration. In some cases, if a cable can't be installed, you'll have to use the "Smartphone" mode. WDS (Wireless Distribution System), which allows routers to be connected over the air, but this can reduce the overall link speed by half.
Preparatory stage: reset and physical connection
Before making any configuration changes, you should clear the secondary router's memory of old settings. This will prevent address conflicts and unpredictable device behavior. A reset is performed by holding down the button. Reset on the back panel for 10-15 seconds until the indicators blink simultaneously.
For the initial setup, connect your computer to the secondary router using an Ethernet cable. Plug one end of the cable into the computer's LAN port, and the other end into any available LAN port on the router you plan to use as a repeater. It's important not to mix up the ports at this stage: the WAN port (often blue or yellow, labeled "Internet") should not be used for now unless you're sure of the connection diagram for your specific model.
Make sure your PC's network card is configured to obtain an IP address automatically. Once connected, open your browser and enter the web interface address. This is usually 192.168.0.1 or 192.168.1.1, but the exact address is indicated on the sticker on the bottom of the device. If the page doesn't open, check the gateway address in the network connection properties.
☑️ Preparing the router for flashing
Setting an IP address and disabling the DHCP server
This is a critical step where most mistakes are made. Two routers on the same network cannot have the same IP address. If the primary router has an address 192.168.1.1, then the secondary one must be assigned a static address from the same subnet, but with a different last octet, for example, 192.168.1.2 or 192.168.1.254.
Change the LAN settings in the secondary router's menu. Find the section Network → LAN and in the field IP Address Enter the new address. Save the settings. After this, access to the router interface will be via the new address, so the connection to the computer may be temporarily interrupted.
The next step is to turn it off. DHCP serversThere should only be one active address provider on the network—your primary router. If DHCP is left enabled on the second device, a conflict will occur, and the devices will not be able to connect to the internet. Find the section DHCP Server and select the option Disable or Off.
| Parameter | Main router | Secondary router (repeater) |
|---|---|---|
| IP address | 192.168.1.1 | 192.168.1.2 |
| DHCP Server | Enabled | Disabled |
| SSID (Network Name) | Home_WiFi | Home_WiFi (or Home_WiFi_Ext) |
| WiFi channel | Auto or fixed | Same as the main one |
Wireless connection and operating mode configuration
Now you need to configure the wireless network itself. Go to the section Wireless or Wi-Fi SettingsHere you need to set the network name (SSID). To ensure seamless roaming (at least partially), it is recommended to set the same name and password as on your main router. However, if you want to manually control which access point you are connected to, you can add a set-top box. _EXT to the name.
Pay special attention to the channel and channel width selection. If the primary router operates on channel 1, then the secondary router should also be configured for channel 1. Using the mode Auto In this case, this is undesirable, as during a reboot, the routers may select different channels, and the connection between them will be lost. The channel widths should match: 20 MHz for stability or 40/80 MHz for speed, depending on the noise level in the air.
⚠️ Note: Router interfaces may vary from manufacturer to manufacturer. Look for sections with similar names, such as "Operating Mode," "Operating Mode," or "Function Mode."
Turn on the mode WDS Bridging or Repeater, if explicitly available. In this mode, the router scans for available networks. Select your main router's network from the list and enter its password. This will create a bridge between the devices. If explicit repeater mode isn't available, simply ensure the SSID and security settings match and DHCP is disabled.
What to do if WDS is not working?
WDS requires support from both routers and is often unstable between devices from different brands. If you are unable to set up a bridge, consider connecting the secondary router via a cable in Access Point mode. To do this, connect the cable from the primary router to the LAN port of the secondary router and select "Access Point" mode.
Device placement and interference elimination
The physical location of the signal booster plays a crucial role. Many users make the mistake of installing the extender in the room where there's no signal. This is incorrect. The device should be within the range of the main router, roughly halfway between it and the "dead zone."
The signal must reach the repeater with sufficient range. If the device receives a barely audible signal, it will not be able to effectively amplify it and retransmit it further. The optimal position is where the smartphone displays 2-3 bars of the WiFi signal bar from the primary point.
Avoid placing equipment near sources of electromagnetic interference. Microwave ovens, wireless baby monitors, Bluetooth speakers, and even aquariums can significantly degrade connection quality. Metal cabinets and mirrors also pose a significant obstacle to radio waves.
Troubleshooting and speed testing
After completing the setup, reboot both routers. Turn on the primary router first, wait a couple of minutes, then the secondary router. Check the connection from your mobile device. If you configured the same network names, it may take a long time for the phone to switch between access points. In this case, try temporarily disabling WiFi on your phone and then turning it back on.
Run a speed test using services like Speedtest. Measure the speed near your main router, then within the range of the extender. A 30-50% speed drop when connecting through a repeater is normal for a wireless bridge, as the channel is split between receiving and transmitting data.
If the internet connection is completely lost, check the secondary router's logs. Often, the problem lies in an incorrectly entered primary network password or a mismatched encryption type (e.g., WPA2 vs. WPA3). Make sure the encryption type is identical on both devices.
Do I need to update the firmware before setting up?
Yes, it's recommended. New firmware versions often contain security fixes and improve the stability of the wireless module. Visit the manufacturer's website, download the latest version for your model, and update the firmware via the web interface before starting configuration.
Is it possible to connect routers of different brands?
Yes, you can. Wi-Fi standards are universal. However, features like fast roaming (802.11r) or specific WDS modes can only work within a single vendor's ecosystem. In a mixed environment, it's better to use universal access point mode.
Why is the speed on the second router lower than on the first?
With a wireless connection (repeater), the channel's bandwidth is split in half because the device cannot simultaneously receive and transmit data on the same frequency. For maximum speed, use a cable connection between routers or a dedicated 5 GHz radio channel for the backhaul.
