I am new to networking, but would like help trying to learn. I have a laptop and a desktop. The laptop is connected to a Linksys WRT54G. Whanted to know if there was a way to go through my desktop tp print. Do I need to add anything.

Everything should be set up fine atm Network wise. Now you have to correctly configure it in windows. You'll have to enable file and print sharing or w/e its called on the computer.
