However, using a proprietary driver from TP-Link This can provide more stable operation and access to additional features, such as real-time signal strength monitoring. In some cases, Windows system updates may replace a working driver with a less stable one, so it's recommended to disable automatic driver updates in the system settings.

Setting up a Wi-Fi connection

After successfully installing the drivers, you need to configure the connection to your wireless network. Click the network icon in the lower right corner of the screen and select your network name (SSID) from the list of available ones. Enter the security password (WPA2-PSK key), which is usually found on the router's sticker if you haven't changed it previously. When you first connect, the system will ask if you want to make this computer visible to others. For home networks, this is typically "Yes," and for public networks, "No."

If you use the utility TP-Link Utility, the control interface will look different, providing more detailed statistics. In the utility window, you can view signal strength as graphs, select a specific communication channel, and view a list of authorized networks. This is especially useful in apartment buildings, where the airwaves are clogged with signals from neighboring routers, and manually selecting a channel can significantly improve speed.

⚠️ Note: Router and operating system settings interfaces may differ depending on the firmware version or Windows update. Always refer to the latest screenshots in the help file for your software version.

For maximum security, it is recommended to use an encryption protocol. WPA2-PSK or WPA3, if your equipment and router support it. Avoid using the outdated WEP protocol, as it's easily cracked and doesn't provide adequate data security. The adapter settings also contain options for managing the operating mode; select mixed mode (802.11b/g/n) for best compatibility.

How to choose the best Wi-Fi channel?
