You can configure a network profile for networks that are listed in the Available networks list as well as networks that are
not listed. When you have completed configuring a network profile, the network name and icon appear at the top of the
Preferred networks list. Your computer automatically connects to the network at the top of the Preferred networks list.
Follow the applicable instruction set below, based on whether or not the network is listed and whether or not the network
requires a WEP key (check with your network administrator to see if a WEP key is required). NOTE—Both the network
name and the network key are case-sensitive.
