So Ive got a iPad 4 gen and a iPhone 4S both running iOS 8.1 and they are rock solid on WIFI. I just got a iPad Air 2 and already had a iPhone 6 that both lose connection to my network regularly. Like they seriously spend half the time disconnected as connected. Now I know it is well documented on the net that there are problems with WIFI and iOS 8.x, but there hasnt been much discussion on here lately and I know a lot of ppl have iPad Air 2s. I guess Im going to have to get a new router but seriously why cant Apple figure out this problem? Since my old devices work on WIFI and iOS 8.x, its obviously a hardware problem with the new network chips in the iPhone 6 and Air 2 and certain (most?) older routers, or could be a software problem in how iOS 8.x talks to the new chip. It just seems to me there should be more discussion on it in here if there were still a lot of people having problems.
