Hello everyone,

I have just recently realized that the 5Ghz doesn't work on one of my two devices. The system works in AP mode and both are connected via Ethernet backhaul.

I think I have tried everything : reboot, factory reset, testing with wireless backhaul, switching the main device. No success.

While the "faulty" one was the main device, I checked the web UI and the 5Ghz was "on" but the channel was "0".

On the other one, everything is fine.

Am I missing something obvious ? Should I check a particular error in the logs to help narrow it down ? Or is it just bad luck and an hardware issue ?

Thank you in advance for any help you can bring. ;)
