I would definitely say so, but is there not some way of getting an ethernet cable so you can re-route your router to your Xbox?
Well bedroom is loft conversion so could be abit of trouble there. Most of the people use the wireless adapters and it just seems easier in my case.
make sure your wireless modem is compatible with the xbox wireless adapter - I know I had to spend ages getting mine to sync up as the xbox wireless adapter uses "old" wireless technology
I assume the new adapter will work with the latest wireless technology and rules
Oh and I have all three - xbox360, PS3 and wii and they are all good at different things - here in the US, you can stream netflix to your xbox360 for free which is pretty cool
I thought you had to pay for the movies you watch on Netflix?
if u have ps3 then online is free so there is no problem...
