ok, let me start out with a little background. I live in an apt with 2 roomates. We all have computers running xp with SP2. we are on a network ( we have a wireless router) so that we can share pictures,files etc together. In the past we have had some problems with people jumping on our network and using it for free. So one of my roomates decided he was gonna "secure" our network. Im not positive but i believe he password protected our router so that it will only recongize traffic coming from our MAC addresses. anyway every since he did that I havent been able to "see" them on the network so I cant send or receive files from them. Well today I opened Windows Media Player ( where i have all my music) and all of my music files were gone!!! i have 8 gigs of music and it is all gone,deleted... I did a search of my computer and i cant find it anywhere! now, I did back up my music on my roomates computer so it isnt gone forever but, since I cant "see" any of them on the network I cant import it back into my media player... Any suggestions? thanx in advance.
