Most home networks don't work because of configuration problems not hardware issues. If you don't have file and printer sharing then you don't have a home network. Have you tried running the wireless networking setup wizard in control panel? Read the instructions? Visited the Linkys website on Home Networking? They have a good tutorial.

Thanks, Byker.  I've run the automated set-up so many times I think I know it by heart; but I haven't checked the Linksys site.  I do have an Internet connection, which I thought was half the battle.  I'll get back to you after I try the Linksys stuff.
