hey! newbie here.. Recently, my iPhone cannot connect to the Wi-Fi eventhough it normally connects before. The phone detects it but it unables to connect with the WI-Fi. At some cases when I access other Wi-Fi areas, the phone can detects it (the Wi-Fi icon appears) but I cannot access to the net. It there a problem in my phone or the router? I'm a bit frustrated about it.. pls help!
