Many users are familiar with the problem of "dead zones" in their apartment or house: a router delivering full speed in one room, but the signal disappears through two walls. In such situations, users often consider purchasing additional equipment to eliminate interference and ensure a stable connection throughout the home. One affordable and popular solution is using a TP-Link TL-WR940N series router as a repeater.
Model TP-Link TL-WR940N Originally designed as a full-fledged router for small apartments, its functionality allows for repurposing. Converting the router into a repeater or access point is an effective way to extend the range of your network without running additional cables throughout the apartment. It requires minimal technical knowledge and takes just a few minutes.
In this guide, we'll walk you through the setup process in detail, focusing on the nuances that beginners often overlook. You'll learn how to properly prepare your equipment, which network settings to change first, and how to avoid common configuration errors. Proper setup wireless mode will provide you with seamless coverage and high-speed internet anywhere.
Equipment preparation and initial diagnostics
Before you begin the software, you need to properly prepare the physical connection. You'll need the router itself. TP-Link TL-WR940N, a power supply, and a network cable (patch cord), which is usually included in the kit. Also, make sure you have access to the main router that's already distributing the internet and know its network settings.
It is important to understand the difference between operating modes. Mode WDS Bridge (Wireless Distribution System) allows you to connect devices over the air, but requires configuration on both routers. Access point mode requires a wired connection between devices. For most users looking to boost their signal without the hassle of wires, the first option, or mode, is the most appropriate. Universal Repeater in new firmware.
Start by checking the device's functionality. Plug the power supply into a power outlet and press the power button on the back panel, if there is one. The lights should light up. If only the power light is lit and the others are not blinking, you may need to reset settings to factory settings to avoid conflicts with the old configuration.
Reset settings and log in to the web interface
The first step in reconfiguring your router is to log into its administrative panel. To do this, connect your computer or laptop to one of the device's LAN ports. TP-Link TL-WR940N Using a cable. Make sure your computer's network card is configured to obtain an IP address automatically.
Open any browser and enter the device's default address in the address bar. For most models in this series, this is 192.168.0.1 or 192.168.1.1The exact address is indicated on the sticker on the bottom of the case. Enter your login and password (the default is most often admin And admin). If you haven't changed them before, you'll be able to log in successfully.
⚠️ Note: If you can't access the interface, check if your router's IP address conflicts with your default gateway address. If both devices have the address 192.168.0.1, change your TP-Link's IP address in the [Default Gateway] section.
Network → LANto 192.168.0.254 before continuing with the setup.
After logging in, it is recommended to immediately change the administrator password in the section System ToolsThis is a basic measure. security, which will protect your network from unauthorized access to equipment settings. Remember the new password, as without it, you will not be able to manage the router in the future.
☑️ Router preparation checklist
Setting up wireless WDS mode
In order to use TP-Link TL-WR940N As a wireless signal booster, you need to activate the WDS function. Go to the menu Wireless → Wireless SettingsHere you need to enter a network name (SSID) and select a region. The network name can be the same as your main router to create a unified space, or different if you want to separate it.
In this same section, find the check mark Enable WDS Bridging and activate it. The "Survey" button will then appear. Click it to have the router scan the airwaves and find available networks. From the list, select your primary network you want to boost and click "Connect." The channel and encryption parameters will be adjusted automatically.
Channel selection is critical. For stable operation in bridge mode, the channels on both routers must match. If the primary router operates on channel 1, then TL-WR940N should also be switched to channel 1. Channel locking prevents connection breaks when the equipment is rebooted.
Why is channel fixation important?
If you leave channel selection set to automatic, the master router may switch to a different, less congested channel after a reboot. In this bridged mode (WDS), the slave router will not be able to automatically switch, and the connection will be lost.
Security and password configuration
Wireless network security is a priority. Go to the section Wireless → Wireless SecurityHere you need to select the encryption type. The best choice for home use is WPA2-PSK (AES). This standard provides reliable data protection and is supported by all modern devices.
In the Password (PSK Password) field, enter the password for your primary Wi-Fi network. Please note that the password must be identical to the password on your main router. Mismatched passwords or encryption types will result in devices not being able to connect or experiencing slower speeds.
Some users wonder whether they need to change the MAC address. In most cases, WDS requires unique MAC addresses, but modern firmware versions TP-Link They handle this automatically. However, if the connection fails, you can try cloning the MAC address of the computer being configured in the corresponding section of the menu.
| Parameter | Recommended value | Description |
|---|---|---|
| Security Type | WPA2-PSK | Reliable encryption standard |
| Version | Automatic | Automatic selection of protocol version |
| Encryption | AES | Data encryption algorithm |
| PSK Password | Main network password | Wi-Fi access key |
LAN setup and disabling DHCP
This is perhaps the most important step, and the one where most mistakes are made. For your network to function correctly, it should only have one server distributing IP addresses. Go to the section DHCP → DHCP Settings and select the option Disable (Turn off). Now TL-WR940N will stop conflicting with the main router for issuing addresses.
Next, you need to check your local network settings. In the section Network → LAN Make sure the second router's IP address is in the same subnet as the first, but not the same. For example, if the main router has an address of 192.168.0.1, the extender can be assigned 192.168.0.2 or 192.168.0.254.
⚠️ Note: After changing your LAN IP address, you will need to restart your computer or refresh its network connection, and you will need to log in to the router interface using the new address. Save the new address to avoid losing access to your settings.
After applying all the settings, the router will prompt you to reboot. Click the button Reboot on the menu System ToolsAfter turning on, the device will attempt to connect to the primary access point. The connection status can be checked in the menu. Wireless → WDS Status, where "Run" or "Success" should be indicated.
Placing the device and checking the signal
The physical placement of the amplifier plays a crucial role in the efficiency of the entire system. The ideal location for TP-Link TL-WR940N — This is the zone where the signal from the main router is still quite strong, but is starting to weaken. This is usually halfway between the router and the "dead zone."
Avoid placing the amplifier in recesses, behind furniture, or near sources of electromagnetic interference, such as microwave ovens or high-power power supplies. The antennas should point vertically upward. If the model has two antennas, you can position them at a 45-degree angle for better coverage.
It's best to test connection quality using a smartphone or laptop in a distant room. Use Wi-Fi analysis apps to ensure the signal strength (RSSI) is in the green zone (above -70 dBm). If the signal is weak, try moving the extender closer to the signal source.
Solving typical problems and errors
During setup, users often encounter a situation where the WDS status shows "Fail" or "Scan." This means the devices can't "see" each other. Check that the channels on both routers match. Also, make sure that MAC address filtering isn't enabled on the primary router, which would block the new device from connecting.
Another common issue is low internet speeds through a repeater. Since WDS mode splits the channel bandwidth in half (reception and transmission are on the same frequency), a speed loss of up to 40-50% is technically normal for single-stream devices. To minimize losses, use the 5 GHz band if your equipment allows it, although the model TL-WR940N works only in 2.4 GHz.
⚠️ Note: The interface and menu layout may vary depending on the hardware platform version (Ver. 1.0, Ver. 6.0, etc.) and firmware version. If you don't see the options described, check the manual for your specific device revision on the manufacturer's official website.
If all else fails, try updating your router's firmware to the latest version. New software versions often contain compatibility fixes and improve the stability of the wireless bridge. You can download the latest firmware from the manufacturer's official website by entering the hardware version number on the sticker.
What should I do if the internet connection disappears after setup?
Check the default gateway on the connected devices. It should point to the IP address of the main router, not the extender. If the gateway is incorrect, double-check your DHCP and LAN settings.
Frequently Asked Questions (FAQ)
Is it possible to connect TP-Link TL-WR940N to a router of another brand?
Yes, WDS mode is a standard protocol, but its implementation may vary between manufacturers. Connection is possible if both routers support WDS and you manually assign each other's MAC addresses. However, the stability of such a connection is not 100% guaranteed.
Will my internet speed decrease when using a booster?
Yes, in wireless bridging mode (WDS), speed inevitably drops because the radio module is both transmitting and receiving data. Under ideal conditions, the loss is approximately 30-50%. For speed-critical applications, a wired connection is better.
How to reset the router to its original state?
To do this, press and hold the button Reset On the back of the device, press and hold the power button for 10-15 seconds until the indicators flash simultaneously. After this, the router will reboot to factory settings.
Does TL-WR940N support 5GHz?
No, this model is single-standard and operates exclusively in the 2.4 GHz band. For 5 GHz networks, you'll need more modern equipment that supports the 802.11ac or ax standard.
