Agree, having wifi problems myself, pretty much have to restart it on every use and that seems to get me around it until the next time it sleeps. I'm at the point of considering going back to iOS 7 on all my devices.
I'm just baffled because we have (among tens of other devices) two iPhones with the same model number and one works and one doesn't. I have some students very happy and some very unhappy. Its not like I can get logs from these folks to figure out what the difference is.
