trouble setting up a home network with problems

I am trying to set up my wireless home network between a Dell desktop and laptop with a Linksys network router and card. I have both the router and card hooked up and they are both showing that they see each other, are connected and have a strong connection. I cannot see anything in either of the network places on either computer though. i know i am missing something stupid and simple or i am not looking in the right place but i can’t figure out what it is. Please help – thanks in advance for your time.
