I bought an Archer TX20U Plus just a few hours ago, and I can't turn on the 5G hotspot.

The 2.4G hotspot works easily, but not the 5G. I have the latest drivers from the website, I’ve tried changing a lot of settings in Device Manager, and I even disabled 2.4G through Device Manager.

I can connect to 5G, the router supports 5G, but the 5G hotspot doesn't work—it just says 'Unable to set up mobile hotspotI bought an Archer TX20U Plus just a few hours ago, and I can't turn on the 5G hotspot. The 2.4G hotspot works easily, but not the 5G.

5G works with the Archer T4U, but the hotspot turns off from time to time, and it's hard to get it back, and I had to change a setting for the wireless mode to 'auto.' However, the Archer TX20U Plus doesn't have this option.
