I have a Proscan PLT-9650G tablet that I have performed a hard rest on. Now, when starting up the tablet, and after selecting a Wi-Fi network, it sits there and checks the network connectivity with a message saying “This may take a while”. The tablet shows that the wireless network it is connected to is at full strength. What could be wrong and what is the fix for this ??? I believe the Android OS is Lollipop 5.1.
