If the wireless LAN is secured by a network key, enter this key,
then tap Connect.
Next time you use your device to detect wireless networks, you
will not see the pop-up message windows again, and you will not
be prompted to enter the network key of the previously accessed
wireless network (unless you perform a hard reset which will
erase custom settings on your device).
Note Wi-Fi networks are self-discoverable, which means no additional steps
are required for your device to connect to a Wi-Fi network. It may be
necessary to provide a username and password for certain closed
wireless networks, however.
To save battery power while connected to a Wi-Fi network
1. Tap Start > Settings > Connections tab > Wireless LAN to
open the Wireless LAN Settings screen.
2. On the Power Mode tab of the Wireless LAN Settings screen,
move the Power Save Mode slider to a position that optimizes
performance with the least power consumption.
