iPhone4 dropped wifi and will not reconnect
iphone4 will not reconnect to wifi.
-wifi on this device has worked with this and other wireless routers.
-tried turning wifi on/off; forgetting network; hard reset, all to no avail. the spinny wheel next to the network name just keeps on spinning, no check mark. password is correct. iOS is latest update.
-tried resetting wifi router; changing password... Firmware on router is latest update.
Still nothing. Other iOS devices work on wifi. PC works on wifi. Just this device wont work.
Took the device to the local Genius Bar. The device worked on their wifi with no problem. Brought it back home, device does not connect to wifi - same problem.
Any ideas?
