Hi, I have a weird problem. My phone connects to the WiFi and shows the icon on the information bar. But I can't browse the internet.. There's no connectivity. (Please note that I can browse internet without a problem with my macbook using the same router same time) If I turn off and turn on the WiFi then I could browse for some time, then again the connectivity will stop. I'm not sure this is a phone problem or a router problem which somehow blocks internet connectivity to the phone. Please advice.
