Live in a house with multiple iOS devices. So far No connectivity issues until today.
work fine:
iPhone 4S on 7.1.2
iPad 3 on 7.1.2
iPhone 5S on 8.0
IPad Air on iOS 8.0
Today, we added two iPhone 6s into the fold.
Both are identical models: Gold, 64 GB, AT&T
One is fine with A+, however the other iPhone
6 will connect for 7-9 minutes, and then it disconnects. It will not
reconnect automatically.
Have tried rebooting, resetting it's network settings, and finally
Resetting all settings on the affected 6. Nothing improves the problem.
I have set up my old router as a repeater, and the iPhone connects without
any issues at all. Mysterious problem!
