Hi all,

I just bought a new USB wireless adapter, TP-Link Archer TX20UH and it does not detect 5 GHz Wifi. 

I have a 5G wireless router that broadcasts both 2.4 and 5 GHz Wifi channels. I have several devices (Android phone, iPhone and iPad) that successfully detect and connect to the 5GHz Wifi, but this adapter can see only 2.4 GHz Wifi. 

I checked the Advanced section of the adapter in Device Manager and 5GHz wife is set to IEEE 802.11a/n/ac/ax but still: the adapter does not detect the 5GHz Wifi, it just doesn't see it. 

I am using the latest drivers I downloaded from TP Link website. 

What can I do, so the adapter will detect 5 GHz channel of the Wifi?
