Wifi 5ghz is everytime stopping any option I choose: the wifi 2.4ghz device is working fine.
In Global 5GHz Settings:I tried, Channel Auto, different Channel lds/width, Country Code (DE, US, World),
In Interface configuration: Tried setting Enbaled=On Mode=AP, Network Lan, WMM Mode; Wireless Security WPA2-PSK, Cipher=Auto,
Evern the default interface created "Rutx12" is not working.
It says "Device status: Running", but the interface itself is stopped.
I tried removed the interface and adding the default device, tried cold reboot, but not working.
Is the device damaged or is it just a software misconfiguration? Where can I see the reason why the device has stopped?
