Many owners of apartments with complex layouts are familiar with the situation when the wireless signal stops reaching distant rooms or the kitchen. Often, the only viable solution is to use additional equipment to extend the coverage area. In this article, we'll cover in detail how to connect another router to a Wi-Fi router, turning it into a repeater or access point.
There are several proven methods for achieving this goal, each with its own technical considerations and speed limitations. The choice of a specific method depends on the model of your primary device, the availability of LAN ports in the remote room, and connection stability requirements. We'll cover wired and wireless connections so you can choose the best option for your infrastructure.
Before physically connecting the cables, you need to prepare both devices for operation. Make sure you have access to the web interface of the main router and know its IP address. You will also need a patch cord (network cable) of sufficient length if you plan to use a wired connection, which is always preferable for ensuring stable speeds.
Choosing a connection scheme: bridge or access point
The first step to expanding your network is determining the operating mode of the second device. Most often, users choose between the following modes: access points and the regime wireless bridge (WDS Bridge)In the first case, the devices are connected with a cable, which guarantees maximum throughput and no speed loss. This option is ideal if there's already an Ethernet outlet in the remote room or you're willing to run a cable.
If a cable connection is not possible, a wireless connection is used. In this case, the second router receives the signal from the first and distributes it further. It's important to understand that when using a wireless bridge, the actual speed on client devices can be reduced by almost half, as the radio module must simultaneously receive and transmit data. However, for watching videos and surfing, this is often sufficient.
Some modern models support Mesh technology, which allows you to create a single, seamless network. Unlike traditional WDS, where each node can create its own subnet, Mesh systems enable automatic roaming of devices between access points without interrupting the connection. If your equipment supports this feature, setup will be significantly simpler and more efficient.
⚠️ Caution: When setting up a wireless bridge (WDS), it is critical that the Wi-Fi channels on both routers are manually fixed to the same value, otherwise the connection will be constantly lost.
Preparing equipment and resetting settings
Before configuring the secondary router, it is strongly recommended to perform a factory reset. This will avoid IP address conflicts and old profiles that could interfere with the proper operation of the new setup. To perform a factory reset, locate the reset button on the router's housing. Reset or Restore, press it with a paper clip for 10-15 seconds until the indicators blink.
After rebooting, connect your computer to any LAN port of the second router using a cable. Do not connect the WAN port of this device to the main network yet to avoid DHCP server conflicts. Open a browser and enter the address printed on the sticker on the bottom of the device; this is usually 192.168.0.1 or 192.168.1.1.
Log in to the control panel using the default login and password (often admin/admin). First, check the firmware version. If it's out of date, it's best to update it to the latest version from the manufacturer's official website, as new wireless bridge algorithms are often added through software updates.
Configuring LAN settings and disabling DHCP
The most important step, where most mistakes are made, is setting up the local network. For two routers to work on the same network, they must be on the same subnet but have different IP addresses. For example, if the primary router has the address 192.168.1.1, then the second one needs to be assigned an address 192.168.1.2 or any other free one in this range.
The second critical point is disabling the DHCP server on the second device. Only one device—the primary router—should be distributing IP addresses on your network. Leaving DHCP enabled on both devices will cause a conflict, and the devices will not be able to obtain the correct network settings for internet access.
To change your address, go to the section Network → LANChange the IP address to a suitable one and save the settings. After this, the router will reboot, and you will need to use the new address to log in again. Then go to the section DHCP Server and select the option Disable or Off.
☑️ LAN Setup Checklist
| Parameter | Main router | Second router (configurable) | Action |
|---|---|---|---|
| IP address | 192.168.1.1 | 192.168.1.2 | Change in LAN settings |
| DHCP Server | On | Off | Disable on the second device |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | Leave unchanged |
| Gateway | 192.168.1.1 | 192.168.1.1 | Specify the IP of the main router |
Operating mode: Access Point
If you're using a wired connection, setup is extremely simple and reliable. After you've changed the IP address and disabled DHCP on the second router, move on to setting up the wireless network. Find the section Wireless or Wi-Fi SettingsHere you need to set the network name (SSID) and password.
You can name the network the same as the one on your main router so that devices automatically switch between them, although this doesn't always work perfectly without mesh protocol support. Alternatively, append "_Ext" or "_Room" to the name to clearly identify which access point you're connected to. It's best to use the same password for convenience.
After saving the settings, physically connect the devices with a cable. Take a patch cord and plug one end into the LAN port of the main router, and the other into LAN port secondary router. Please note: in access point mode, the WAN port on the second device is typically unused and remains free.
⚠️ Note: Firmware interfaces may differ. If you don't find an exact match for a menu item, look for sections titled "Operation Mode," "Operation Mode," or "Advanced Settings."
Why doesn't the internet work after connecting the cable?
Most often, the problem is that the cable is plugged into the WAN port of the second router instead of the LAN port, or the DHCP server hasn't been disabled. Check these two things first.
Wireless bridging (WDS)
When cable installation isn't possible, WDS technology comes to the rescue. This mode allows a second router to receive a Wi-Fi signal and broadcast it further. To get started, go to the wireless settings (Wireless Settings) on the second device. Find the check mark Enable WDS Bridging and activate it.
Once activated, a "Survey" or "Search" button will appear. Click it. The router will scan the air and display a list of available networks. Select your primary router's network from the list. The system will automatically fill in the MAC address and network name (SSID). Enter the password for your primary Wi-Fi network in the "Key" field.
It's important to set the wireless channel. If the primary router is set to "Auto," change it to a specific number (e.g., 1, 6, or 11 for the 2.4 GHz band). The channel on the second router must be identical. Channel mismatch is the most common reason why the bridge fails.
Some manufacturers, such as TP-Link or Asus, have their own simplified bridging utilities called "Repeater Mode" or "Media Bridge." If your router supports this mode, use it, as it automatically disables DHCP and configures WDS without manually adjusting complex settings.
Device placement and signal physics
The effectiveness of network expansion directly depends on the location of the second router. A common mistake is installing the extender in a "dead zone," where the signal from the primary router no longer reaches, or reaches it extremely weakly. In this case, the second device will have nothing to rebroadcast.
The ideal location for installation is at the edge of a strong reception zone. Here, the primary router's signal is still stable (at least 2-3 bars on the indicator), but is already beginning to weaken. A second router located in this zone will receive a strong signal and transmit it further into the remote area.
Interference should also be considered. Avoid placing the equipment near microwaves, baby monitors, or mirrored surfaces, which can block the signal. Both routers' antennas should be oriented vertically for optimal coverage.
Diagnostics and problem solving
Once setup is complete, test your network. Connect your smartphone or laptop to the second router's network. If you have internet access but the speed is slow, try changing the Wi-Fi channel to a less congested one. You can use mobile apps like WiFi Analyzer.
If the devices connect but the internet isn't working, check the default gateway. The IP address of the primary router should be listed as the gateway in the connection properties on the client device. Also, make sure the security type (WPA2/WPA3) and encryption method (AES/TKIP) match on both devices.
If you experience constant connection drops in bridge mode, try lowering your wireless standard. 802.11n/ac to 802.11g or mixed mode. Sometimes older encryption algorithms perform more reliably over longer distances than newer, interference-sensitive protocols.
⚠️ Note: If you're using the 5 GHz band, remember that it has less penetration through walls than 2.4 GHz. For bridging two or more brick walls, it's best to use the 2.4 GHz frequency.
Frequently Asked Questions (FAQ)
Is it possible to connect routers from different manufacturers?
Yes, you can connect devices of any brand (for example, TP-Link And D-Link) via a LAN cable in access point mode. For wireless bridging (WDS), compatibility depends on both devices supporting the same standards, but most often, equipment from the same brand or chipset is required for stable operation.
Will my internet speed decrease when I connect a second router?
With a wired connection (LAN-to-LAN), speed won't drop if the cable is in good condition and supports the Gigabit Ethernet standard. With a wireless connection (repeater or bridge mode), speed may drop by 30-50% due to the overhead of signal retransmission.
Do I need to buy a special cable to connect routers?
In most modern cases, a standard straight-through patch cord (Cat5e or Cat6) is sufficient. Previously, crossover cables were required, but modern equipment automatically detects the connection type (Auto-MDI/MDIX), so any standard cable will do.
Will devices see each other on the local network?
Yes, if you've properly disabled DHCP on the second router and assigned it an IP address from the same subnet, all devices will be in a single namespace. You'll be able to transfer files over LAN, display images on DLNA TVs, and use network printers without restrictions.
