HELP!! OK I consider myself fairly computer savvy and network savvy. I build my own computers and can have setup my wireless network at home. I have 2 laptops, a desktop, Xbox360, Wii, and a few other electronics that access the internet via the wireless router. I have ZERO issues getting these devices to see the network and use the Internet.

BUT...I cannot for the life of me get any of these devices to see each other. I cannot share any files or printer. My Xbox360 cannot stream from my desktop (but I followed their directions exactly...just cannot find once setup). All the computers are running XP.

I have a Buffalo Wireless N-Infinity Router.

Please help any idea what setting I am missing or what I am doing wrong. I even download Network Magic and it was useless (it say everything but nothing could talk to each other)

Thanks for any help.
