Modern models of this device feature a user-friendly web interface that allows even non-technical users to manage settings. However, a basic understanding of network logic is still necessary to avoid common mistakes.
In this article, we'll cover the entire process, from unpacking the equipment to fine-tuning security and wireless connection settings. You'll learn how to properly connect cables, log in to the admin panel, and select the optimal settings for your provider. We'll pay special attention to security, as default passwords and open networks pose a serious threat in today's environment.
Equipment preparation and physical connection
Before starting software configuration, you need to properly organize the physical connection of the device. Router TL-WR845N It's equipped with color-coded ports, which significantly simplifies the connection process. It's important not to confuse the WAN port (usually blue), where the cable from the ISP connects, and the LAN ports (yellow), which are used to connect computers or laptops.
First, connect the power supply to the socket Power on the back of the device and plug it into a power outlet. The indicators on the front panel should light up, indicating power is supplied. Then, use the included network cable (patch cord) or any other working cable. CAT5e or higher.
Insert one end of the cable into any of the yellow ports. LAN, and the other plug into the network port of your computer or laptop. If you plan to configure the router via Wi-Fi, find the network name (SSID) and default password on the sticker on the bottom of the device. Connecting to the factory network is the first step to managing it.
- 🔌 Plug the power adapter into a power outlet and press the power button, if there is one on the case.
- 🌐 Insert the ISP cable into the blue port

Make sure your computer's network card settings are set to obtain an IP address automatically. In the operating system Windows This can be verified by going to the adapter settings and protocol properties IPv4If static addresses are specified there, they must be reset to automatic, otherwise the computer will not be able to "see" the router.
Login to the web management interface
After a successful physical connection, you need to log into the device's control panel. To do this, open any browser (Chrome, Firefox, Opera) on the connected computer. Enter the router's IP address in the address bar. For the model TP-Link TL-WR845N the default address is 192.168.0.1 or domain name tplinklogin.net.
When you navigate to the address, the system will request authorization. The factory login and password are usually the same. adminThis information is also indicated on a sticker on the bottom of the case. In newer firmware versions, the security system may require you to create a new administrator password upon first login—this is normal practice and should be followed.
⚠️ Attention: If the standard address
192.168.0.1If the router doesn't open, check the default gateway IP address in your network connection properties. The router's address range may have been changed previously or conflict with another network.
The control interface may differ depending on the firmware version (green or blue design). However, the menu layout remains the same. The main sections are usually located in the left vertical panel or in the top horizontal menu, where the tabs are grouped. Network, Wireless And System Tools.
Setting up a connection to a provider (WAN)
The most important step is setting up an internet connection. To do this, go to the menu Network and select a subsection WANHere you need to select the connection type your provider uses. This information is usually provided in your contract or on the service provider's website.
The most common types of connections are Dynamic IP (dynamic IP), Static IP (static IP), PPPoE, L2TP or PPTPIf your ISP didn't provide you with any special login information, you're most likely using a dynamic IP address, and you don't need to change any settings—your internet will work as soon as you connect the cable.
In case of using technologies PPPoE (often used by providers like Rostelecom, Dom.ru) or L2TP (Beeline), you must enter the login and password provided by your provider. You may also be asked to provide the server name or VPN address. Incorrect login or password will result in loss of network access.
| Connection type | Required data | Frequency of use |
|---|---|---|
| Dynamic IP | Not required | High (MGTS, local networks) |
| PPPoE | Login, Password | High (Rostelecom, Dom.ru) |
| Static IP | IP, Mask, Gateway, DNS | Average (Business rates) |
| L2TP/PPTP | Login, Password, Server Address | Average (Bilein, old networks) |
After entering all the parameters, click the button SaveThe router will attempt to establish a connection. You can check the connection status on the main page (Status), where an IP address other than 0.0.0.0.
Wi-Fi wireless network configuration
Wireless mode settings are made in the section Wireless (or Wireless Settings). Here you can change the name of your network (SSID) to any convenient name. It is recommended to give the network a unique name to avoid confusion with neighboring access points.
Next, you need to go to the security settings (Wireless Security). It is critical to choose the encryption type. WPA2-PSK (or WPA3, if supported). This is the most secure standard currently available. Avoid using outdated encryption. WEP, which can be hacked in a few minutes.
Create a strong Wi-Fi password that includes both letters and numbers. The password must be at least 8 characters long. In the field Version It is better to leave the mixed mode or choose WPA2-PSKto ensure compatibility with all devices, from smartphones to smart light bulbs.
- 📡 Change the network name (SSID) to something unique that does not contain personal information.
- 🔒 Set the protection type WPA2-PSK for maximum safety.
- 🔑 Create a complex password that is difficult to crack using brute force.
- 📶 Select your region of residence to ensure proper signal strength.
⚠️ Attention: After changing Wi-Fi settings, all connected devices will be disconnected. You'll need to reconnect to the network with the new name and password on each device.
You can also use this section to limit the maximum number of users or set up a wireless network schedule if you want Wi-Fi to turn off at night.
Changing the administrator password and updating the system
Factory password admin is known to everyone who has access to your network, so changing it is a mandatory security step. Go to the menu System Tools and select PasswordYou will need to enter your old password and the new one twice.
In addition, the manufacturer periodically releases firmware updates (Firmware), which fix bugs and patch vulnerabilities. You can check the current firmware version on the main status page. An update can be performed automatically through the menu. System Tools -> Firmware Upgrade, if the router is connected to the Internet, or manually by downloading a file from the official website.
Why update firmware?

After changing the administrator password and updating the software, it is recommended to reboot the device through the menu System Tools -> Reboot, so that all changes take effect completely.
☑️ Router security check
Additional features and MAC address cloning
Some providers bind internet access to a specific device, identifying it by MAC addressIf you previously connected the internet directly to your computer, your ISP may have "remembered" your computer's network card. In this case, you'll need to "disguise" your router as that computer.
To do this, go to the menu Network find the item MAC CloneThere you can press the button Clone MAC Address, and the router will copy the MAC address of the network card from the computer you're using to configure it. After this, you'll need to save the settings and reboot the router.
Also worth paying attention to is the function DHCP ServerIt's enabled by default and assigns IP addresses to devices on your local network. Unless you have specific requirements, you don't need to change DHCP settings. However, if you plan to use the router as an access point, you'll need to disable DHCP.
On the menu Forwarding You can set up port forwarding if you need to open up your computer to external access, for example, to run a game server or for video surveillance. However, keep in mind that open ports reduce security.
Diagnostics and solution
If the Internet does not appear after setting up, first check the indicator WAN On the router body. If it's not lit or flashing, the problem is physical: the ISP cable is damaged or there's a failure on the service provider's end.
If the indicator is on, but there is no network access, check the logs in the section System Tools -> System LogThere may be messages about authorization errors (incorrect PPPoE login/password) or a connection failure. Also, try cloning the MAC address as described above.
If you lose access to the control interface (the settings page won't load), perform a factory reset. There's a button on the back panel. Reset (or hole). Press and hold it for about 10 seconds with the router turned on until all the indicators flash simultaneously.
⚠️ Attention: A reset will erase all your settings, including your provider settings and Wi-Fi password. You'll have to set up the router again from scratch.
