So a few weeks ago had no WiFi on our 3GS and 4 for days (it worked fine right before after the update). So after restoring numerous times, finally worked again. Lo and behold, today, just like before... no WiFi unless I'm within like 5 feet of the router. I'm in my home office on the other side, and it keeps going from 3G to 1 bar of WiFi sometimes. I know it's not the router, impossible, I have a good N router and my Macbook Pro picks up the signal all the way on my dock behind the house. All other devices work fine, and our iPhones worked fine before on the network. But even then, I've reset and changed parameters in the router, no difference. Only after the iOS 5 update does this keep happening. Nobody else on here has this problem? This seems to be the only Mac forum with like no post about it. Elsewhere online you can find tons and tons of post on this. Like from Apples Discussions: https://discussions.apple.com/thread/3381610?start=0&tstart=0 Why it's only affecting some and not others, and why some things (Resetting etc) fix it and not others... no idea, but it's irritating as hell. My local Apple store said they've had people come in with their phones after updating saying their having WiFi issues, but they don't show anything in their system from Apple nor online does it look like Apple is even addressing this issue.
