Good day.

Thank you for your patience.

Is the 5Ghz still detectable, but not able to be connected, or it is not able to be detect?

May I know the model number of your main router?

If possible, please try to modify the advanced wireless settings, such channel 40/48, channel width 40mhz for 5ghz;

And please also try to update the driver to be the following one:

Archer T2U_V3
