For me, no device connects to the 5 GHz network of the WRT3200. Unknown channel is displayed in the status. Has someone had that before? Do I have to switch the expansion channel from ll to uu, had read times that it is inverted with BCM or has it already been fixed.
I changed the channel because some channels have apparently been deactivated since the last update of the Raspberry PI4.
Allowing channel overlap does not matter to me whether activated or deactivated I can select all extension channels LL, LU, UL and UU, so I wanted to know what the standard is so that I can set it that way.
I have the issue where the channel reads unknown on the 5GHz radio if I select the option on for "single user beamforming". If I unselect it, I get a proper channel displayed. I have the 1200AC though and it is on an older release, 43443. It has been an issue for me form a couple years, but at least I know what causes it (for me anyway). I would check that option though under the Wireless tab --> Basic settings subtab --> then click the advanced options on the 5GHz radio.
