I have had my Ace for over 9 months now, and until 2 weeks ago, I have been able to connect to my WiFi at home with no problem. Since 2 weeks however, the WiFi on the phone shows that it has full signal but does not actually work - when i try to search on google or refresh BBC news for example, it says i have no internet connection. Please help. I do not know why it does this, or what caused it, I just need a fix quickly! All help is appreciated.
