When I am connected to the internet via WiFi and try to watch a video the phone asks me if it should connect via "WiFi" or "Mobile Network". Clicking on Mobile Network gives the error "Connection Failed", understandably. Clicking on "WiFi" makes the phone show the message "01% Buffering" for about 20 seconds, only to tell you "Connection Failed" afterwards. I've never been able to watch a video online for this reason. Can't find anything in the manual about this.
