I recently moved and the wifi channel with least interference is channel 13. My iPad, iPhone and pc work perfectly with this channel however my mba only recognises channel 1-11 and thinks it's in the US or at the moment DE. I rang customer support and they determine I had a US spec wifi card therefore they arranged an appointment with the genius bar. At the genius bar they turned my mba on and it registered as GB country code therefore I'm led to believe it's this stupid virgin superhub that is doing something to make the MBA think it's not in Great Britain. HELP!
