I'm the ultimate scrub.

Ok, I just formatted my computer, but now I don't have the internet on it.  It's wired through a router via my main computer, (the one I'm on now) but it's still not getting internet access.  So I'm thinking, I need to nab the router CD (Linksys WRT54G) to install on my computer, and that should fix the problem.  Only thing is, I don't have the CD anymore.

Is there any place I can download the CD, or am I going about things completely wrong?

HEEEEEEEEEEEEEEEEEEEEEELP!!!

You don't need to install any "router software". Assuming both your computers are plugged into the router's built in switch, you only need to enable DHCP (automatic) configuration in the computer's network interface's TCP/IP settings. If that alone doesn't help (or the network interface doesn't show up) you may need to install drivers for the net work interface.
