Samsung Galaxy Ace won't connect to wifi

[sneaky cat]

My Samsung Galaxy Ace used to connect to wifi seamlessly, but now it wont connect to any wifi network. Does anyone know what to do? I tried rebooting it and using wifi fix and rescue.

Thanks.

If nothing else works you may want to try a factory reset.

from my Sony Xperia Tablet Z or XTZ or "Ecstasy"

Tried that, still wouldn't connect.
