5 GHz signal seems to have given up. No change to the setup, the 5GHz light is still on (at the front of the device), and I've rechecked all the settings, but nothing can see it at all. The 2.4 channel is still ok. WiFi antenna app doesn't show anything at 5GHz (Samsung S3), and none of the devices (printer, ipad, android etc) can connect.
I've tried turning it off and back on again. Any other suggestions?
