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.
