How do I prevent my wireless card from being accessed by others?

I recently installed a Linksys WUSB11 wireless card in a second computer. It
feeds off of my DSL Gateway on another computer in order to gain internet
access. When I connect my wireless computer to the internet and right-click
on the icon in the task bar, I see my new wireless account, but I also see my
linksys appearing as an unsecured wireless network.

How do I secure this to prevent someone from logging on to my account?
