text: i have an x-box 360.is there anyway to set it up on a wireless modem. i already have one for my laptop.? i have a cable isp running through a linksys wireless router and i like to set up a system i can run my xbox (which is in another room) off my router. your cheapest alternative is to buy the linksys wga11b gaming adapter (between $30 and $50 depending on rebates).  if you want to fork out the dough, buy the xbox 360 wireless adapter (its $100 but runs at 611.a)  i have been running the wga11b with my linksys wireless b wireless router and it works pretty smooth for gaming.  if you are wanting to stream stuff off your computers then you will want to go with a g or a wireless protocal though.
