I am having the same problem. My wifi will turn itself off with no notification, in the middle of a solid reliable connection. It also won't remember my home network password but connects to my work wifi automatically. Baffled.

You got a bad flash you have to re flash the modem you got remnants of the old kernel in there and old modem so what you need is a clean flash hopefully you won't loose anything tho if you want to stay stock take it to a best buy and get the Samsung experience rep

Since my last s4 update my wi-fi turned off with no notification; used all my mobile data in four days. Is this a "problem" or simply that one needs to re-check settings?
