What can I Do if my wireless adapter cannot detect 5G Wi-Fi?

Case 1: Cannot see any 5G Wi-Fi.

Suggestions:

1. Disable the old wireless adapter. 

To disable the other adapters, click on Control Panel-> Network and Internet-> Network and Sharing Center-> Change Adapter Settings on the left side. Only keep the Cudy wireless adapter on and check the Wi-Fi list again if you can see the 5G Wi-Fi or not. 

Or go to Device Manager and find old wireless adapter, then disable it.

2. Update the latest driver from the official website.
