Got my iPad November 7th, worked great on my home wifi. Upgraded to 4.2, now my wifi connectivity is intermittent - it seems to cycle on and off. Apple telephone support tried to tell me that this could be because my router is wireless g instead of wireless n. I find it very hard to believe that Apple would not have made the iPad backward compatible to work with the type of wireless used by the majority of people. I suspect this is a continuation of the wifi bug that delayed the release of the update and the phone support dude didn't want to deal with it. Anyone else have this problem and any fixes?
