How do I setup a wireless router on my desktop computer when I'm using a PCMCIA Card to access the internet?

I have a desktop computer (Windows XP), using a PCMCIA card (Sierra AirCard 875) to connect to the internet through Cingular. I want to connect a Linksys wireless router (Wireless-G 2.4 GHz) to the desktop, so I can also access the internet from my other computer (which will have a LInksys wireless adapter). How do I configure the desktop and router so I can have wireless on my laptop?
