Many apartment owners face a situation where their internet provider provides high speeds, but their router physically can't cover the entire space with a signal. Thick walls, mirrors, or simply the distance between rooms create "dead zones" where the connection drops or is minimal. In such cases, the question often arises: can an old router lying around unused be used to expand the coverage area?
The answer to this question is yes, but it requires careful consideration of equipment selection and setup methods. An old device can become fully functional. repeater, access point, or bridge, significantly improving connection quality in the far corners of your home. However, not all models support the necessary features, and the setup process may vary depending on the manufacturer and firmware version.
In this article, we'll take a detailed look at the technical nuances that will help you revive an old gadget and turn it into a powerful network expansion tool. You'll learn about the differences in operating modes, security configuration details, and methods for avoiding common mistakes when setting up a wireless bridge.
Selecting the right equipment and checking compatibility
Before you begin setup, you need to make sure your second router (the one that will boost the signal) is technically capable of doing so. Not every device can operate in receiver or repeater mode. First, check whether your hardware platform supports this feature. WDS (Wireless Distribution System) or mode Wireless Client.
Pay attention to wireless standards. If your main router distributes internet according to a standard 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6), and the second router only supports 802.11n, the speed at the second point will be limited by the capabilities of the old equipment. Moreover, when using WDS, the channel throughput is often reduced by half due to the specifics of data packet relaying.
⚠️ Attention: When using WDS mode, the wireless connection speed may drop to 50% of the actual speed of the main channel, since the extender router is forced to simultaneously receive and transmit data on the same frequency.
It's also important to consider the availability of antennas. If the second router has removable antennas, this offers a significant advantage: you can replace the stock antennas with more powerful or directional ones, significantly improving signal reception from the main router. Built-in antennas in compact models often don't provide sufficient gain for stable operation in client mode over long distances.
Basic operating modes for network expansion
There are several ways to turn a regular router into a range extender, each with its own unique features. Understanding the differences between them will help you choose the optimal strategy for your specific situation. The choice of mode depends on how important speed is, whether you need a wired network at the second point, and whether the equipment supports the necessary features.
The first and most common method is the regime WDS bridgeIn this case, the routers communicate over the air, and the second router distributes the internet connection further, creating a single network with the same name (SSID). This is convenient for roaming, when devices automatically switch between access points. However, as mentioned earlier, this method can be unstable when mixing equipment from different brands.
The second option is the regime Client (Client Mode) or Access points (Access Point) with a wired connection. If it's possible to run an Ethernet cable between rooms, this is the best option. The second router receives the signal via the wire and distributes it via Wi-Fi. This ensures maximum speed and stability, eliminating losses along the wireless path from the backbone to the amplifier.
The third, lesser known method is the regime Repeater (Repeater), which is implemented in software in some firmware (for example, OpenWrt or DD-WRT). Unlike WDS, it uses software relaying, which sometimes allows connecting devices from different manufacturers, but requires more in-depth knowledge of network configuration.
Preparing for setup: reset and addressing
Before making any changes to network settings, you must reset the second router to its original state. This will prevent conflicts between IP addresses and saved profiles, which could interfere with the correct operation of the new scenario. Resetting is accomplished by holding down the button. Reset on the back panel of the device for 10-15 seconds until the indicators blink.
A critical step is to change the IP address of the second router. By default, most devices have an address 192.168.0.1 or 192.168.1.1If your main router has the same address, a conflict will occur, and you will lose access to both devices. You need to log into the web interface of the second router (connecting directly via cable) and change its LAN IP to a unique one, for example, 192.168.1.254.
☑️ Preparing the router for setup
After changing your IP address, don't forget to disable the service. DHCP servers On the second router. In our setup, the primary router remains the primary address distributor. If DHCP remains enabled on both devices, clients on the network will receive incorrect gateway and DNS settings, resulting in internet access failure.
Setting up a WDS bridge: step-by-step instructions
Let's look at the setup process for the most popular, though not always stable, method—WDS. First, log into the main router's interface and find the wireless network settings. You need to set the Wi-Fi channel. If it's set to "Auto," select a specific number (for example, 1, 6, or 11 for 2.4 GHz) so the second router can reliably find the network to connect to.
Write down the security settings: encryption type (usually WPA2-PSK) and password. This information must be identical on both devices. Now let's move on to the second router. In the wireless settings, select the option WDS or Enable WDSOnce activated, a "Search" or "Survey" button will appear, displaying a list of available networks.
Find your main router's network in the list and click "Connect." Make sure the SSID and channel match the settings on your main device. Enter the information for your main network in the security type and password fields. After saving the settings, the router will reboot and attempt to establish a connection.
| Parameter | Main router | Second router (amplifier) |
|---|---|---|
| Opening hours | Access point (AP) | WDS / Bridge |
| IP address | 192.168.1.1 | 192.168.1.254 (example) |
| DHCP Server | On | Turned off |
| Wi-Fi channel | Fixed (eg 6) | Same (6) |
If the WDS status shows "Successful" or "Connected," the bridge has been established. Devices connected to the second router should receive IP addresses from the main router and have internet access. If an error occurs, check that the password is entered correctly and that the encryption types match.
Alternative Methods: Client and Repeater Mode
If WDS doesn't work or devices from different manufacturers refuse to "be friends", you can try the mode Client (Client Mode). In this mode, the second router connects to the main router's Wi-Fi network like a regular device (laptop or phone) and distributes internet through its LAN port or creates its own Wi-Fi network with a different name.
The advantage of Client mode is that it often offers more stability than WDS, as it doesn't require full bridge protocol compatibility. However, the downside is the need to create a separate subnet or complex routing configuration if you want devices (printers, NAS) to see each other.
⚠️ Attention: In Client mode, the second router can create a separate Wi-Fi network with a different name. Switching between networks on mobile devices will be manual; there will be no automatic roaming.
For advanced users, there is the option to install alternative firmware, such as OpenWrt or DD-WRTThese systems allow you to turn virtually any compatible router into a universal tool. With their help, you can configure the mode Repeater Bridge, which combines the benefits of WDS and Client, creating a single network without losing the functionality of LAN ports.

Optimization and troubleshooting
After setting up the network, it's important to optimize it to ensure maximum performance. Place the second router in an area where the signal from the main router is still strong enough (at least 2 bars on the signal level), but closer to the "dead zone." If the extender is placed too far away, it will transmit a weak and noisy signal.
Use different frequency bands if your equipment allows it. Configure your main router to broadcast 5 GHz, and leave the second router (if it's older) on 2.4 GHz for compatibility with older devices. Alternatively, use 5 GHz for the WDS backbone to avoid cluttering the airwaves.
Check the signal level using special applications on your smartphone (for example, WiFi Analyzer). Make sure your channels don't overlap with your neighbors' networks. If you experience significant noise, try changing the channel to a clearer one in both router settings.
It's also worth checking that the second router isn't overheating. Constantly relaying data can put more strain on the device's processor than regular internet access. Ensure adequate ventilation.
Frequently Asked Questions (FAQ)
Is it possible to connect routers from different manufacturers via WDS?
In theory, the WDS standard is uniform, but in practice, different manufacturers (for example, TP-Link and Asus) often implement it differently. Compatibility is possible, but not guaranteed. It's best to use equipment from the same brand or use universal client mode.
Will my internet speed drop when using a booster?
Yes, with a wireless connection (WDS/Repeater), the speed inevitably drops, often by half, due to the channel operating in half-duplex mode. With a wired connection (Access Point), the speed loss is minimal.
Do I need to enter the MAC address of the second router in the settings of the first?
Some router models (especially older ones) require you to enter the client's MAC address in the main router's WDS settings for authorization. In modern devices, this often happens automatically.
What should I do if my devices can't see the second router's network?
Check that the SSID Broadcast feature is enabled. Also, make sure you're connecting to the correct frequency (2.4 or 5 GHz) and that your device's network adapter drivers are up to date.
