Expanding the coverage area of a wireless network often becomes a necessity in large apartments, country houses, or office spaces where the signal from one device simply does not reach distant rooms. Connecting a second router To the point, this is the most effective way to solve the problem of "dead zones" without running unnecessary cables throughout the house. Modern devices from the company TP-Link offer several flexible scenarios for organizing such a connection, allowing the creation of a unified infrastructure.
In this article, we'll explore the technical nuances of combining routers into a single subnet using a wireless connection. You'll learn about the differences between operating modes, such as WDS bridge And client mode, and also receive a step-by-step guide for setting up your equipment. Proper configuration will help you avoid IP address conflicts and ensure stable data transfer speeds throughout your entire room.
Before you begin setting up, it's important to understand that the second router will act as a signal receiver or repeater. Wireless connection Between devices, secure communication requires precise adherence to security and channel parameters, otherwise stable operation will not be achieved. We'll look at the process using popular models from the series as an example. Archer And TL-WR, whose interface is the most common.
Selecting the optimal device connection scheme
The first step is always to determine how exactly your devices will interact. There are two main ways to accomplish this: creating WDS bridge (Wireless Distribution System) or using the mode Client (Client). In the first case, both routers remain active access points, creating a single network with a single name (SSID), allowing devices to automatically switch between them, although this isn't always ideal (seamless roaming requires support for mesh protocols, which older models lack).
Client mode turns the second router into a pure receiver, distributing the Internet further, but to its own subnet, unless bridge mode is configured. WDS This requires both devices to operate on the same channel and have the same encryption settings. This is a more complex but functional scheme for connecting buildings or floors without losing the network name.
If you just need to “throw” the Internet to another room and distribute it there via cable or create a new network with a different name, the mode will do Client or Repeater (if supported by the firmware). The choice depends on your specific local networking needs and the availability of features in your hardware menu.
⚠️ Note: Web configurator interfaces may differ depending on the hardware version and firmware version. The layout of menu items may vary, so look for sections with similar meanings if the exact names are different.
It is important to take into account that when using a wireless channel for communication between routers (Backhaul), the actual speed on the second device will always be lower than on the first. This is because the radio module cannot simultaneously receive and transmit data at full speed in the same frequency range. Therefore, for mission-critical tasks such as online gaming or 4K streaming, a cable connection is preferable if technically feasible.
Preparatory work and resetting the settings
Before you begin configuration, you need to prepare the equipment. It's best to start with reset settings Reset the second router (the one you'll be connecting to) to its factory defaults. This will prevent conflicts with old configurations and ensure a clean experiment. To do this, hold down the button on the powered-on device. Reset for 10-15 seconds until the indicators flash simultaneously.
You will also need to know the exact parameters of the main network: network name (SSID), encryption type (usually WPA2-PSK or WPA3) and a password. Without this information, it is impossible to configure the wireless connection. It is recommended to write down the MAC address of the main router, as some WDS modes require manual entry.
☑️ Equipment preparation
Connect your computer to the second router using an Ethernet cable to any LAN port (or via WiFi, if it's broadcasting a signal by default). Access the web interface by entering the address in the browser's address bar. 192.168.0.1 or tplinkwifi.net. The default login credentials are often found on a sticker on the bottom of the device, usually admin/admin.
At this stage, it is important to change the IP address of the second router so that it does not conflict with the main one. If the main router has an address 192.168.0.1, then the second one needs to be assigned, for example, 192.168.0.254This is done in the section Network → LANAfter changing the address, the device will reboot, and you will need to enter the new IP address in the browser to continue using it.
Setting up the main router for WDS
If you've chosen the WDS scheme, setup begins with the main device that distributes the internet. You need to set the wireless network channel, as both devices must operate on the same frequency for the bridge to work. In the main router's menu, go to Wireless → Wireless Settings.
In the field Channel select a specific value, for example, 1, 6 or 11 for the 2.4 GHz band. Do not leave the value Auto, otherwise, when switching channels, the connection between the routers will be broken. Also, make sure that the mode is enabled Enable Wireless Router Radio and the mode is set 11bgn mixed or similar, supported by both devices.
Why can't I leave the Auto channel?
With automatic channel selection, the router periodically scans the airwaves and can switch to a less noisy frequency. In WDS mode, the second router will lose connection with the first one because it's searching for it on the old frequency, while the first one is already broadcasting on the new one.
Next, you need to enable the bridge function. In the section Wireless → Wireless Bridge or WDS check the box Enable WDSAfter this, a button will open. Survey or Search, which you'll see a list of available networks. Find your primary router's network in the list (if you're setting it up from a second device) or simply note the MAC address.
In some firmware versions TP-Link You must manually enter the MAC address of the remote device. Enter the MAC address of the second router in the corresponding field on the main device if the interface requires it. However, most often, it's enough to configure the second router to match the settings of the main router.
| Parameter | Main router | Second router (Client/Bridge) |
|---|---|---|
| IP address | 192.168.0.1 | 192.168.0.254 |
| DHCP Server | Enabled | Disabled |
| Channel | Fixed (eg 6) | Same (6) |
| SSID (Name) | Home_Wifi | Home_Wifi (for roaming) |
Configuring the second router in bridge mode
Now let's move on to setting up the second device that will receive the signal. After changing the IP address and rebooting, log in to its interface. Go to the section Wireless → Wireless Settings. You need to install it here. exactly the same channel, which was recorded on the main router.
Find the item below Enable WDS Bridging (or just WDS) and activate it. A button will appear Survey (Search). Click it, find your primary network in the list and click ConnectThe system will automatically insert SSID And BSSID (MAC address) of the main router.
In the field Key Type And Key (Password) Enter the password for your primary WiFi network. The encryption type must match the primary one (usually WPA2-PSK, AES). After saving the settings, the router will attempt to establish a connection. You can check the status in the section Status, where confirmation of a successful WDS connection should appear.
The critical step is to turn it off DHCP servers on the second router. Go to DHCP → DHCP Settings and select DisableIf you leave it enabled, your network will have two devices distributing IP addresses, leading to conflicts and internet outages for connected clients. Only the main router will control the internet.
Networking in Client Mode
An alternative to WDS is the mode Client, which often operates more reliably across different router models, as it doesn't require WDS support from the primary device. In this mode, the secondary router connects to WiFi like a regular device (laptop or phone) and distributes the received internet connection.
To activate this mode, go to the second router menu Operation Mode (Operating mode) and select Client or Wireless ClientThe device will reboot. After logging in, find the section Network → Internet or Wireless, where a list of available networks is available.
Select your primary network from the list and enter the password. Unlike WDS, you don't need to manually enter channels or MAC addresses—the second router will automatically find and connect to the access point. However, it's important to remember that in this mode, the second router creates separate subnet.
⚠️ Note: In Client mode, devices connected to the second router will be on a different subnet than the devices on the main router. For example, you won't be able to display an image from your laptop on your TV via DLNA if they are connected to different routers without additional, complex routing configuration.
In client mode, the DHCP server on the second router is usually disabled automatically or can be left untouched, as it receives an IP address from the main router for its WAN port and distributes addresses from its own subnet (NAT) to its clients. This creates a "double NAT," which can interfere with some online games or torrents, but is perfectly acceptable for casual surfing.
Troubleshooting and Speed Optimization
After setting up, you need to check the connection quality. Connect the device to the second router and run a speed test (for example, via SpeedtestIf the speed is significantly lower than expected (less than 40-50% of the plan speed), try changing the antenna placement or moving the second router closer to the first.
A common problem is interference. If there are a lot of neighboring networks around, use WiFi analyzer apps (for example, WiFi Analyzer (on Android) to find the least congested channel. Even if the channel is fixed, you can change it to a freer one on both routers simultaneously.
Also make sure both devices are running the latest versions. firmware (Firmware). Manufacturers frequently release updates that improve wireless bridge stability and fix security issues. You can check for updates in the section System Tools → Firmware Upgrade.
If the connection constantly drops, check whether power saving is enabled on the wireless module (if this option is available in the advanced settings). Make sure there are no thick concrete walls with reinforcement or metal screens between the routers that could block the signal.
Is it possible to connect routers from different manufacturers via WiFi?
Technically, the WDS standard is a proprietary extension and is often incompatible between different brands (for example, TP-Link and Asus). For connecting disparate devices, it's better to use the Repeater or Client, if they are supported by both devices, or use universal protocols, but it is impossible to guarantee stability in WDS bridge mode between different brands.
Will the internet speed decrease on the second router?
Yes, wireless connections inevitably slow down, often by 30-50% of the primary channel's speed, as the radio operates in half-duplex mode (taking turns receiving and transmitting). Using the 5 GHz band for communication between routers helps minimize losses.
Do I need to set static IP addresses for clients?
No, if you've configured DHCP correctly (enabled only on the main router in WDS mode), all devices will automatically receive the correct IP addresses from the main router's pool. Manually assigning IP addresses is only necessary in rare cases of specific networking needs.
