Connecting your Android tablet to a Wi-Fi network instead of using mobile data is more cost effective, especially for large downloads such as updates, games and applications. To make the connection, the Wi-Fi setting on your tablet must be active and there must be available networks within range. Your tablet automatically detects all available networks, but you must enter a password to connect to secure networks. The Wi-Fi settings for your tablet are accessible from the "Connections" section of the settings screen.
Tap the "Apps" icon -- represented by a grid of squares -- and then tap the "Settings" icon. Alternatively, swipe down from the top of the screen and then tap the gear-shaped "Settings" icon.
Select "Connections" and then tap the icon next to "Wi-Fi" to activate the Wi-Fi on your tablet. If the icon next to "Connections" is already green, it means that the Wi-Fi is already activated and you don't have to do so manually.
Tap the name of the Wi-Fi network to which you want to connect from the list of options displayed.
Type the password and tap "Connect" if the network is secured and requires a password. The word "Connected" is displayed below the network name to indicate that your tablet is now connected.
