Forget a Wi-Fi network
You can make the tablet forget about the details of a Wi-Fi network that you added—for example, if you don’t want the
tablet to connect to it automatically or if it is a network that you no longer use.
Turn on Wi-Fi, if it’s not already on.
1
In the Wi-Fi settings screen, touch the name of the network.

Set a Wi-Fi disconnect policy
By default, the tablet disconnects from Wi-Fi when the screen turns off and connects to a mobile data network instead.
It does this to conserve battery power, and reconnects to Wi-Fi again when you wake it.
You can change this policy to stay connected to Wi-Fi when the tablet is connected to a charger (when battery life isn’t a
problem), or never to disconnect from Wi-Fi, which trades battery life for reduced mobile network data use.
On the Wi-Fi settings screen, touch Wi-Fi disconnect policy.
