Lucky I did a search as I am sitting in the same boat and rowing with psychdoctor here.
I need to do something very similar. I already have a Linksys WRT54G router. I also have the Xbox Wireless adapter from my original Xbox. I have been using this to run my Xbox360 with no problems in my media room which is about 20 ft away from my office where the internet connection comes in. I now need to run my Xbox360, Tosh HD A2 HD DVD player, and my DirectTV HR20 and was hoping to use some of my existing hardware. Can I somehow use my current router to the xbox wireless adapter. Then hook up another hub to run all three devices off the same connection. Or is there another way to run off my current WRT54G. Or do I need to scrap the current setup and use something better / faster.
Thanks for any ideas. Hope this isnt to much of a hi jack of psychdoctor thread.
