Many users are familiar with the situation where the WiFi signal doesn't reach distant rooms or the second floor of the house. Often, the solution lies not in purchasing expensive equipment, but in properly configuring existing devices. If you have an old router lying around or have purchased a second one, TP-Link To expand the coverage area, they can be combined into a single local network without laying extra cables.
There are several ways to implement such a scheme, and the choice of a specific method depends on your goals and the equipment model. You can set up a wireless connection WDS Bridge, turn the second router into an access point, or use repeater mode if supported by the firmware. Each option has its own nuances for configuring IP addresses and broadcast channels.
In this article, we will take a detailed look at how to technically correctly connect two devices of the brand TP-Linkto ensure they operate stably and avoid address conflicts. We'll cover preparing the equipment, changing network parameters, and performing a final connection test. Proper configuration will allow you to create a unified network with roaming or simply extend your internet range.
Preparing equipment and choosing a work scheme
Before starting any work, it's necessary to determine the architecture of the future network. The most common setup is one in which the first router (the primary router) distributes the internet, while the second (the secondary router) receives the signal via WiFi and broadcasts it further. To successfully implement this, both devices must be in good working order and their software (firmware) updated to the latest version. Find out the exact models of your devices in advance, as the menu interface for the series varies. Archer And TL-WR may differ.
A critical step is to reset the secondary router to factory settings. This will eliminate any conflicts with old configurations that may have been left over from previous use. On the back of the device, locate the recessed button. Reset or WPS/ResetPress it with a paperclip and hold it for about 10 seconds until the lights flash simultaneously. After this, the device will reboot with a clean slate.
⚠️ Important! Make sure you reset the secondary router. Resetting the primary device, which is your internet connection, will result in the loss of your provider settings and temporary loss of internet access.
You'll also need a computer or laptop with a network adapter for the initial setup. While modern smartphones allow you to manage routers through apps, for in-depth configuration of IP addresses and MAC filters, it's more convenient to use a full-featured browser on your PC. Connect your computer to the secondary router via cable or WiFi, using the information on the sticker on the bottom of the router.
Configuring the main router for bridge operation
If you are planning to use the technology WDS (Wireless Distribution System), then settings are required not only on the receiving router, but also on the main router. Log in to the main device's web interface by entering its IP address (usually 192.168.0.1 or tplinkwifi.net) in the browser's address bar. Find the section responsible for wireless mode, which is often called Wireless or Wireless mode.
In the WiFi settings, you need to fix the broadcast channel. The default value is AutoThis is unacceptable for bridging, as changing the channel will break the connection between the routers. Select any available channel, such as 1, 6, or 11, and save the settings. Also, write down the MAC address of the main router; you'll need it to enter it into the second device.
Check if WDS is enabled in your wireless network settings. On some newer models TP-Link With Blue Interface firmware, this feature may be hidden or replaced with "Access Point" or "Repeater" mode. If there's no explicit WDS option, your model may only support client or repeater mode, which simplifies the process since you don't need to change anything on the main router.
Why is it important to fix the channel?
If the channel remains in Auto mode, the main router may automatically switch to a less congested channel when rebooting or when the radio environment changes. The secondary router, configured on the old channel, will lose connection, and the network on the second floor will be unavailable.
Configuring the secondary router's IP address
The most common source of problems when merging networks is IP address conflicts. By default, both routers TP-Link have the same address, for example, 192.168.0.1For them to work together, the addresses must be unique. Connect to the secondary router's interface and go to the section Network → LAN (Network → Local network).
Change the third octet of the IP address. If the main router has an address 192.168.0.1, then ask the secondary one 192.168.0.254 or 192.168.0.2The main thing is that the last digit is different. After applying the settings, the router will ask you to reboot, and you'll have to use the new address to access its settings again.
An important step is to disable the DHCP server on the secondary device. In a single network, there should only be one server distributing addresses—the main router. Find the section DHCP and select the option Disable (Disable). If this is not done, devices connected to the second router may receive incorrect gateway settings and be unable to access the internet.
Setting up a WDS wireless bridge
Now let's move on to directly connecting the devices over the air. In the secondary router's menu, go to the wireless settings. Make sure the network name (SSID) and channel match the settings of the primary router if you want to create a single network with a single name. However, WDS bridging often requires creating a separate access point or using a special scanning function.
Click the button Survey (Review) or Search in the WDS settings. The router will scan the air and display a list of available networks. Find your primary network in the list and click Connect (Connect). The device will automatically insert the MAC address of the main access point. All you need to do is enter the main network's WiFi password in the corresponding field.
☑️ Checking bridge settings
After enabling the WDS function and entering the password, the connection status should change to Run or ConnectedThis means the logical bridge is established. Now the secondary router receives internet from the primary router and broadcasts it. Devices connected to the second router will see the network as if they were connected to the primary router, but are on the same subnet.
Comparison of modes: Repeater, Access Point and Client
Understanding the differences between operating modes will help you choose the best option for your situation. Not all models TP-Link Support all connection types, but knowing the theory will help you navigate the menu better. Below is a table comparing the main characteristics of the modes.
| Parameter | Repeater Mode | Access Point (AP) mode | Client Mode (WDS) |
|---|---|---|---|
| Connecting to the main router | Wireless (WiFi) | Wired (LAN-WAN) | Wireless (WiFi) |
| Data transfer rate | Reduced to 50% | Maximum (without losses) | High, depends on the signal |
| Availability of wired LAN ports | They work (usually) | They are working actively | They work as a bridge |
| Difficulty of setup | Low (WPS) | Medium (requires cable) | High (manual settings) |
Repeater mode is convenient because it doesn't require cables, but it cuts the channel speed in half because the radio module transmits and receives simultaneously. Access point mode is ideal if you can run a cable between floors or rooms—this way, you'll get maximum speed and stability. Client mode (or WDS Bridge) allows you to connect wired devices (TVs, set-top boxes) in a second room to the first router's network via WiFi.
⚠️ Please note! Menu interfaces and item names may vary depending on the router's firmware version and hardware revision. Always consult the official instructions on the manufacturer's website for your specific model.
Diagnostics and troubleshooting
After setup, check the network's functionality. Connect your smartphone or laptop to the second router. If you have internet access but the speed is slow, try changing the WiFi channel to a less congested one using WiFi analyzers, such as WiFi AnalyzerInterference from neighboring networks can significantly reduce the bridge's throughput.
If the devices connect but have no internet access ("No internet access"), check your DNS settings. Try entering the DNS servers in the WAN or LAN settings of the secondary router (if it's in router mode) or on the client device. 8.8.8.8 And 1.1.1.1Also, make sure the time on your routers is synchronized if you use scheduled filtering.
If the connection is constantly interrupted, check the distance between the routers. For stable WDS bridge operation, the signal strength on the receiving end must be at least -70 dBm. If the signal is weaker, it's best to move the devices closer together or use a wired connection where possible.
Why doesn't the second router see the first router's network?
This could be due to several reasons: mismatched regional settings (for example, one router is configured for the US and the other for Russia, which affects available channels), different security standards (WPA2/WPA3), or different frequencies (2.4 GHz vs. 5 GHz). Make sure both devices are operating in the same frequency range.
Is it possible to connect routers of different brands?
Yes, the WDS standard is universal, but implementations may vary between manufacturers (TP-Link, D-Link, Asus). It's often easier to configure "Client" or "Repeater" mode on a secondary router, which is typically more compatible with external access points than WDS Bridge mode.
Will my internet speed decrease when connecting via a WiFi bridge?
Yes, when using a wireless bridge (repeater or WDS), the actual speed for clients connected to the second router will be reduced by approximately 30-50% of the speed received by the first router. This is a physical limitation of the half-duplex mode of the radio channel.
