5ghz wifi doesn't work

hi
I'm new here and already get helps and fix 3 problems so thsnk you

just wondering why 5ghz dbm doesn't show any thing and can't accessible

try n and ac what should I change ?


That status is what you'd expect to see with the AP up but no station connected.

Being a CLI user I would read the logs for any wifi-related errors and run iw dev to see if the APs exist.

sorry I'm new to all of this

2.4ghz perfectly ok
but can't find 5ghz with any of my devices

I'm not familiar with ssh command
any thing I can do in luci to make it work ?

set channel 36, set mode ac, set width 80 and try again

In China, channels 36 to 68 are DFS. You will have to wait for the radar check to complete before the AP starts transmitting. Channels 149-161 are unrestricted and should start immediately.

The log can be viewed in Luci by clicking Status on the top bar then System Log.

You should go to the software section and look for updates. Install all updates and reboot the system than give a try. If this is not working try to change country code on wifi and restart the wifi. I set my to GY.
