it is the first time I raise up a question in here. After upgarde to OS 4,if I turn off the ipad and start it again, it cannot connect to network automatically like b4 it is on OS 3.2.2., I need to click mail or click the web page then it will start to connect....and with the window said " not connected...." then on line... Anyone know how to solve ? Thank 100x
1. Reboot the router (unplug it from its power source) 2. Reset your network settings - tap Settings > General > Reset > Reset Network Settings 3. When your iPad restarts, tap Settings > WiFi > Other and re-enter your network name, security, and network password.
