Help WiFi suddenly stopped working

[RussWWFC]

I have been happily using WiFi on my Samsung S3 for the few months that I have had it. However, since last night it has not been able to send or receive data from my home WiFi.

Nothing has changed at all with the connection - password and everything all the same and it shows as connected. Internet access available on all my other devices too, so it's not an issue with the connection itself.

And I can get data fine through carrier - a flurry of messages and notifications came through when I turned WiFi off, but I am on a highly restricted data plan

Tried everything I can think off - turning wifi on and off, resetting phone, but nothing seems to work

Have you tried to "forget" the wifi network on your phone, then scan, reconnect, and sign back in?
Sometimes a reset of the router can help from what I hear

Tried both of those, still no joy

Had a keyboard issue come up recently too - keeps defaulting to the crappy Samsung one rather than SwiftKey, hope there is a fix soon
