Hi,

 

I have installed my TP-Link T3U Archer WiFi adapter on a raspberry Pi. I have installed the rtl88x2bu driver (also see this post) to get it working:

 

 

 

I am able to use all of the allowed 2.1 GHz channels, but for the 5 GHz channels I am only able to use the channels up to channel 48:

 

I can't find any WiFi networks with channels above channel 48, nor can I set up an access point with a channel above 48. Is this a limitation of the Realtek 88x2bu driver for Linux, or is there a way to be able to use the channels above 48?

 

My region has been set to NL:

 

 

I have also tested it with a TP-Link AC600 T2U nano and TP-Link Archer T2U Plus WiFi adapter with the Realtek 88XXau driver, but this same problem occurs with those adapters aswell.
