Model: Archer T4U  
Hardware Version: V3
Firmware Version: 1030.38.712.2019

After a recent Windows 11 update, the Wi-Fi network cannot find the 5GHz band, only the 2GHz network is visible. I tried changing all wireless modes on the adapter to 802.11a/b/g/n/ac, but the 5GHz band is not visible. On other devices, the 5GHz band is visible (cell phones and laptops). I already tried re-installing the driver and also using a different USB port too.

  @David-TP My internet provider sent me the permission to access my router. I was able to change it to channel 36 and everything worked fine. Thank you very much.

Hi, it is suggested to install the beta driver here to see whether it helped or not:

By the way, could you please help me check what is the current 5GHz wireless channel on the host router?

Thank you very much and best regards.

  @David-TP hello, the beta driver didn't work. My 5GHz wireless channel is 128.

Hi, Thanks for the feedback.

Can you change the wireless channel of 5Ghz to a regular one, such as band 1(channel 36-48), instead of using the DFS channels?

Best regards.
