Installation and initial configuration of a router often raises questions among users, especially when it comes to older but time-tested models such as TP-Link TL-WR940NThis three-antenna device remains a popular choice for small apartments due to its reliability and ability to penetrate walls better than many modern compact alternatives. Proper device configuration is the foundation for stable internet throughout your entire local network.
In this article, we'll cover the entire process in detail: from physically connecting cables to the intricacies of wireless broadcasting setup and protecting against unauthorized access. You'll learn how to avoid common mistakes when entering provider data and how to optimize your signal for maximum speed. Follow the steps carefully will allow you to launch a network in 15-20 minutes without calling a technician.
Before moving on to the software, make sure the equipment is ready for use. Check the complete package: the router itself, the power supply, and the patch cord (short network cable). Missing any of these items will make setup impossible. Also, prepare your internet service provider contract in advance, as it may contain important login information.
Physical connection and equipment preparation
Start by choosing the right location for your router. Ideally, place it in the center of your apartment or close to where you most frequently use Wi-Fi, and make sure it's high enough so the antennas don't interfere with anything. Connect the power supply. TP-Link TL-WR940N to the power supply, after which the indicator will light up PWRIf it doesn't light up, check the socket and the adapter itself.
The next step is to connect the router to your computer or laptop for initial setup. Take the yellow network cable from the kit and plug one end into any port. LAN (They're usually numbered 1 through 4), and the other end should be connected to your PC's network card. It's important not to mix up the ports: don't touch the cable from your ISP for now.
⚠️ Caution: If you connect the ISP cable to the LAN port instead of the WAN port, an IP address conflict will occur and you will not be able to access the router settings. The ISP cable should only be inserted into the blue port.
WAN(or the port with the globe icon) after completing the basic setup.
After connecting the cable, pay attention to the indicators LAN on the device's body. One of them should light up or start blinking, indicating successful physical contact between the computer and the router. If the indicators are silent, try replacing the network cable or checking the network card drivers on your computer.

- 📶 Make sure the cable from your provider is disconnected from the device.
Login to the router management web interface
To access the settings, go to the device's web interface. Open any browser (Chrome, Firefox, Opera) on a computer connected to the router via cable. Enter the default IP address in the address bar. For most models TP-Link, including the WR940N series, this is the address 192.168.0.1 or domain name tplinkwifi.net.
After entering the address, the system will request authorization. By default, your login and password are used. admin for both fields. This information is also indicated on the sticker on the bottom of the device. If the default data doesn't match, the router may have been previously configured and a factory reset will be required.
⚠️ Note: Older firmware versions may require you to select a language when you first log in. If you see a language selection window, select Russian or Englishto continue. Do not close the browser window until the authorization process is complete.
In new firmware versions (green interface), the system may immediately offer to launch Quick Setup (Quick Setup). This is an automatic wizard that will automatically detect the connection type, but for guaranteed results and a clear understanding of the process, it's best to select manual mode or carefully follow each step of the wizard. Older interfaces (orange and white) immediately open the main menu on the left.
What to do if the page 192.168.0.1 does not open?
Check if your network card is set to obtain an IP address automatically. Go to Control Panel -> Network and Internet -> Network and Sharing Center -> Change adapter settings. Right-click your connection, select Properties -> Internet Protocol Version 4 (TCP/IPv4), and make sure "Obtain an IP address automatically" is checked.
Basic WAN setup and connection type
The most critical step is setting up your internet connection (WAN). Go to the menu Network (Network) -> WANHere you need to select the connection type your provider uses. The most common are Dynamic IP, Static IP, PPPoE (common for Rostelecom and Dom.ru), and L2TP/PPTP (for Beeline and some others).
If you selected PPPoE, you'll need to enter the login and password provided by your provider in the fields that appear. This information is often specified in the contract. For this mode Static IP You'll need to manually enter the IP address, subnet mask, gateway, and DNS servers provided by your service provider. Even a single digit error will result in no internet connection.
| Connection type | Required data | Provider example |
|---|---|---|
| Dynamic IP | Not required (automatically) | Home networks, offices |
| PPPoE | Login, Password | Rostelecom, Dom.ru |
| Static IP | IP, Mask, Gateway, DNS | Dedicated lines |
| L2TP/PPTP | Login, Password, Server Address | Beeline |
After entering all the parameters, click the button Save (Save). The router will attempt to establish a connection. You can check the connection status on the main status page (Status), where in the WAN section an IP address other than 0.0.0.0If the connection is not established, double-check your login and password or contact your provider's technical support.
☑️ Checking WAN settings
Setting up a wireless Wi-Fi network
Let's move on to setting up the wireless mode. In the menu, select the section Wireless (Wireless mode) Here you need to enter the name of your network (SSID). It's recommended to use Latin letters so that all devices, including older phones and printers, can see the network correctly. The name should be unique to avoid conflicts with neighboring networks.
Next, go to the subsection Wireless Security (Wireless Security) To ensure security, select the encryption type WPA2-PSK (or WPA/WPA2). This is the most secure standard at the moment. In the field PSK Password Create a complex password of at least 8 characters, containing letters and numbers.
⚠️ Caution: Don't select WEP security, as it can be easily cracked with specialized software in just a few minutes. Also, avoid "Open" mode (no password), as it can be used by your neighbors for illegal activities.
An important parameter is the wireless network channel (Channel). The default setting is "Auto", but in apartment buildings this can lead to unstable operation due to airwave congestion. The optimal channels for the 2.4 GHz range are 1, 6 and 11, as they don't overlap. If your internet is slow, try manually switching the channel to one of these.
- 📡 Enter a unique network name (SSID) in Latin letters.
- 🔒 Select encryption type WPA2-PSK for maximum protection.
- 🔑 Create a complex password using letters and numbers (at least 8 characters).
- 📶 Manually select channel 1, 6 or 11 for signal stability.
MAC address cloning and additional features
Some ISPs bind service to a specific device, identifying it by its MAC address. If you previously connected the internet directly to your computer, your ISP may have "marked" your network card. In this case, you need to teach your router to "pretend" to be that computer. This feature is called MAC address cloning.
It is located in the menu Network -> MAC Clone. Click the button Clone MAC Address (Clone MAC Address) to copy the current computer's network card address to the router settings. Afterwards, be sure to save the settings (Save) and reboot your device. Changes may not take effect without rebooting.
Also worth paying attention to is the function DHCP Server. It must be enabled (Enable) so that the router automatically assigns IP addresses to connected devices (phones, laptops, TVs). If DHCP is disabled, you'll have to manually assign IP addresses to each device, which is extremely inconvenient.
Troubleshooting and firmware updates
During operation, situations may arise where the internet connection drops or the speed decreases. First, check the indicators on the device: is the indicator light on? WANIs the indicator flashing? WLANIf the WAN indicator isn't lit, the problem is with your cable or ISP. If it's lit but there's no internet, the settings may be out of order or an update may be needed.
To update the firmware, download the latest version from the manufacturer's official website that matches your hardware version (indicated on the sticker, for example, Ver 4.0 or Ver 6.0). In the router menu, go to System Tools -> Firmware Upgrade and select the downloaded file. The process will take several minutes, and you must not interrupt it.
⚠️ Please note: Firmware for different hardware versions (Ver. 1.x, Ver. 4.x, Ver. 6.x) is not compatible with each other. Installing the wrong firmware will brick the router, which can only be repaired with a soldering iron and a programmer.
If nothing helps, use the button Reset on the back panel. Press and hold it for 10-15 seconds while the router is turned on (it's easier to do this with a paperclip). The device will reset to factory settings, and you'll have to go through the entire setup process again, but this often resolves software issues.
Why does the TP-Link WR940N router cut speeds above 50-70 Mbps?
The WR940N model is a budget model and is equipped with a limited-performance processor. It is physically unable to handle encrypted traffic at high speeds (100 Mbps and above) without packet loss. For plans above 50-70 Mbps, routers with gigabit ports and a more powerful CPU (AC standard) are recommended.
How often should I reboot my router?
For stable operation of any equipment, a preventative reboot is recommended. In the case of TP-Link WR940N It's recommended to reboot your device (unplug it from the power outlet for 10 seconds) at least once a week. This clears the RAM of temporary errors and resets frozen processes.
Can this router be used as an access point?
Yes, you can. To do this, go to Settings. DHCP and disable the DHCP server. Then, connect the cable from the primary router to the LAN (not WAN) port of the second router. The IP address of the second router should be changed to an address in the primary router's subnet to avoid conflicts.
What should I do if I forgot my router settings password?
If the default admin/admin passwords don't work and you don't remember the changed password, a hard reset will help. Press and hold the Reset button for 15 seconds. This will reset the router to its factory defaults, including the Wi-Fi password and provider settings.
