My phone has suddently stopped receiving proper Wifi. at home, it finds my wifi network but when I try to browse, it just hangs there. At another site, the phone simply didn't see all the networks that my computer could, although the network strenght of all relevant ones was very good. So, what could be the problem - physical damage (i've dropped it once past the several days, but didn't notice anything, plus it has fallen on much harder surfaces and from higher points that the other day...), emerging software bug? thanks!
