I have a TC in bridge mode connected to my router purely for using Time Machine for my MBP and iMac. It had been working fine for the last year but over the last week it has suddenly decided to stop working. It stops becoming visible over wifi and when I try and run the Airport Utility on the connected iMac it just hangs and will not let me change or check any settings. Every time I must perform a hard reset and go through the whole setup procedure again. Obviously this is not ideal and was wondering if anyone has any ideas on how to sort it out?
