I currently have a home network for sharing the internet, printing and sharing files. No passwords or restrictions on anything except for the encryption on the wireless, and read/write access to most of the shared drives. the computers run mostly XP, with my media computer running Win7. What I would like to do is set up a different network, just wireless, for the sole purpose of sharing content from my media pc which has movies and tv programs on, but with no access to the internet, and with only read-only access to my files. I have a spare wireless router that I plan to use, and a spare network card for the media pc.
I know this can be done, I just am unsure how to go about it. Can anyone help me out, or point me in the direction of a handy site.
