Lumia 928 Suddenly will not connect to Wifi anymore

[WPCentral Question]

I have a Nokia Lumia 928 and the Wifi suddenly stopped working. I have gotten the error message password is incorrect and Connection Unsuccessful every time i try to connect. I have had no problems since I bought the phone a year ago. I can connect to the router with other devices. The phone wont connect to different routers or public wifi. I get the same error every time. The Phone is running Windows Phone 8.0 3G works just fine

I have tried
-Soft and Hard Resets
-Router Resets. I have tried WPA-personal and WPA2-Personal settings and no security.
-deleting all the know networks and trying to log in again
-the router is up to date and no updates to either the phone or router took place when the wifi quit working.
-Turning wifi on an off in regular mode and airplane mode

Please help! This is wildly frustrating. I can see no reason why the Wifi should just quit working.

Sounds like a hardware failure of some kind.

Hard reset your phone, is the problem gone? No? Then it's a hardware failure. Contact Nokia and see what they can suggest. If it goes away then great! You just solved your problem.
