adding a new laptop to security incripted wireless system

Hello, I have a new Dell 600 (3rd computer) with an external wireless card to
add to my home security incripted wireless system. A second desktop is
wireless connected and works fine. The new laptop doesn't even detect the
home wireless system. I tried the system at free WIFI coffee shop and could
connect there.
Help.
