Hi, My name is***** will assist you.I am sorry to hear that you are having this issue.
Airplane mode disables your device's ability to send or receive any type of wireless transmission.
If airplane mode is turned on, your Samsung Galaxy Tab can't connect to the network.
Tap the Wi-Fi slider to ON.
The device will automatically search for available networks.
To connect, tap the preferred network.
I forgot to tell you that the tablet will not accept the password ***** are using. How do I put in a new password ?
