i want six wired rooms (pc's, xbox's, ps3's) and wireless for my laptops.

any suggestions for routers / what cable to get?

cat5? 5e? 6?

can i even get a wireless router that will support six or more wired connections?

i can't ever see them being online at the same time.

edit: i guess i'm not really "networking" everything together, i just want to have access in a lot of rooms.
