Well, after a couple of years my TimeCapsule is acting a bit off! It appears that the 2.4g wifi has failed. The 5ghz is still working but unfortunately my iPhone, printer and ipodtouch can't use it. Anyone got any tips? The unit thinks it's working with everything good on the airport utility summary but no network seen! I don't really want to buy a new time machine but also don't want to daisy chain another wifi device. I use an ethernet connection from my router to the time machine.
