At home, all my devices (iPad, iPhone 3GS and 4S, a Macbook and two Windows PCs) are connected to the same wi-fi router (Netgear) and all of them connect to the internet perfectly except the iPhone 4S. It shows up as connected to the router, but doesn't load any webpage or do anything that requires web-connection (including checking email). These functions work just fine if I switch the wireless off and switch to 3G!!
I reset the settings and reset the network settings, but nothing helped. If I switch off my phone and switch back on, the wi-fi works for a few minutes and then the same thing happens.
Does anyone know how to resolve this? Please help.
