My wifi has failed and my only hint is the messsage from the dmesg log when I try to connect or scan for access points (list comes up empty).

does any wise wizard here know if I can test/sync/flash/poke the wifi module somehow?

I would hate to have to ship my unit from Iceland to the USA for service if I can fix this via firmware.
