Iphone 4S wi fi connectivity is dropping intermittently.. I did give a call to the support no and they adfvised to reset .. but after the reset I still face the same issue..
Do I need to change the phone or is there some solution for this problem.. this problem is happening ater the Iphone4S upgrade to new iOS5.1.1 upgrade..
Settings > General > Reset > Reset Network Settings
Also, if this only happens with one Wi-Fi network, power cycle that Wi-Fi router.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these in order.
