5 GHz channels

Hi LorenzoBianconi,
thank you very much for your contribution of the mt76 firmware!
I have an issue to connect to the 5 GHz wifi channels. If I set the router to channels 36, 40, 44 and 48, I can connect with it. But, if I set to other channels such 52 and above, I'm unable to connect.
My router is Fritz!Box 6591 cable and my usb wifi stick is FRITZ!WLAN USB Stick AC 860.
I can connect to the router with the internal wifi card of my laptop with any channels.
I can provide you any logs, but you got to tell me which one...
Thank you.
Best regards,
Anmeld

@anmeld Do you mean you are using mt76x2u/mt76x0u in AP on channel 52, right? IIRC 52 is a DFS channel and DFS is not supported on usb,
anmeld commented
Thank you for quick response.
In Germany, it is allow to use the DFS channel. The router will check and ban the DFS channel for up to 10 min. After that the DFS channels will be released, if there is no high priority user. According to the technical manual fritz!wlan usb support the 5GHz bandwidth 5.47~5.725 GHz.
And I have no problem connecting to my router with an internal wifi card by intel.
LorenzoBianconi commented
Sorry, I did not get your environment. Is mt76x2u/mt76x0u used as AP or STA?

I'm using fritz!wlan usb with mt7662u as station mode.
LorenzoBianconi commented
Ok, thx. Could you please run wpa_supplicant in debug mode and post the
output?
Regards,
Lorenzo

I have difficulty to understand the output log, see the attachment. This what I did:
- sudo service network-manager stop
- sudo pkill -9 wpa_supplicant$
- wpa_supplicant -dd -u -f $LOG -B
- mt7662u/usb reconnects to the router with channel 36.
- I changed to channel 56.
- I tried 2 times to reconnect and failed.
- I changed to channel 36 back again.
- Reconnect worked for channel 36.

@anmeld what kernel version are you running? Moreover while scanning can you please run 'iw event' in another terminal?
anmeld commented
@LorenzoBianconi I'm running 5.3.0-2-amd64.
The logs shows the station usb trying to connecting the router which at that moment is set to a higher freq channel.
'iw event' output:
