☑️ Pre-installation check
Setting up a wireless network connection
Once the drivers are successfully installed, the adapter is ready to use. To connect to your home network, click the Wi-Fi icon in the Windows system tray or run the utility. TP-Link Wireless Utility, if you prefer it to the standard Windows interface. In the list of available networks, find your router's name (SSID).
Enter the security password. Please pay attention to your keyboard layout and case sensitivity, as passwords are sensitive to these settings. If the network is hidden, select "Hidden network" and manually enter the SSID.
| Parameter | Description | Recommendation |
|---|---|---|
| SSID | Wireless network name | Choose a network with the highest signal strength |
| Security | Type of protection | Use WPA2-Personal or WPA3 |
| Channel | Transmission channel | Automatic or 1, 6, 11 (for 2.4 GHz) |
| Mode | Opening hours | 802.11n mixed or 802.11b/g/n |
If the connection fails, try forgetting the network in Windows settings and reconnecting. It's also worth checking if your router has MAC address filtering enabled, which could block new devices.
What to do if the network is not visible?
Make sure your router is broadcasting in the 2.4 GHz band, as this model does not support 5 GHz. Check to see if the SSID is hidden in the router settings. Try moving the adapter closer to the signal source for the initial setup.
Using Soft AP (Access Point) mode
A unique feature of the adapter TL-WN823N The ability to operate in Soft AP mode. This allows you to turn your computer with a wired internet connection into a Wi-Fi access point, distributing the signal to smartphones, tablets, or other laptops.
