Hey Vinny,
I have a Linksys wireless g router. I have 3 desktops hard wired to it, my son's xbox360 hard wired and 2 laptops with wireless. My deck is about 60 feet away from the end of the house with the router and I don't have any problems at all. If you "share" your desktop pc and it has music on it you can play it thru your laptop also. And you can also share your printer. The only thing I would recommend is to "secure" your network, especially if you live in a populated neighborhood. you don't want your neighbors sharing anything with you. -Al
