How can I connect to the Internet by wireless on Fedora 7?

I have a laptop (Inspiron B130) from Dell, and it has a
wireless card
(Intel(R) PRO/Wireless 2200BG Network Connection). I also
have a
wireless connection established through a linksys router.
How can I
connect my laptop to the Internet by wireless? Thank you.

Sincerely,

Adrian Mowrey
