Case1: Can not see any 5G Wi-Fi.
The old wireless adapter that doesn't support 5G installed on your computer may affect the 5G wifi broadcasting of the TP-Link wireless adapter, so if you are unable to see the 5G wifi, please disable the old wireless adapter following the steps:
To disable the other adapters, please click the WIN on the keyboard, then input the network. Open the View Network Connection. Then check the Wi-Fi list again if you can see the 5G Wi-Fi or not. If not, please go to case2.
