Note: This FAQ is only for the dual-band wireless adapter and wireless router.

 

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.

Case 2:Cannot see the 5G Wi-Fi of your router

If you have an old wireless adapter, please disable it first to check if it's working.

If the same story, please do the following troubleshooting:

 Open the management page of your main router, go to the wireless settings, then change the channel of 5G Wi-Fi to 36. Then check the Wi-Fi list again. Here we take the TP-Link router as an example

 

It might be affected by DFS, for the details, please refer to :

If the 5G Wi-Fi still does not show in the Wi-Fi list, please contact the support team.
