I recently got myself an xbox 360, I run 4 computers off my dsl connection for all 4 computers plugged into my billion adsl router. But I was stuck, I have an xbox 360 downstairs in the lounge room (split level), so grabbing a 15m cable to go downstairs to the xbox 360 was just not good enough for me. So I went wireless. I bought two Buffalo Air Station Turbo-G's, here's a detailed specific sheet, same place where I bought mine from ->

Pre-flashed with a modified firmware, they give an example of the firmware used here ->

So.. What I did, I set one up as the AP and connected it to my billion router via lan cable. I then put the second Buffalo unit downstairs and plugged it into the xbox 360. And it works like a charm. Streams media perfectly, getting a good signal, even though I had some interferance from other channels I bought myself a cheap pci wireless network adapter just to throw into the pc, and using the software net stumber, scanned the channels to find the one with the least amount of interferance. I set the second buffalo unit thats connected to the xbox 360 up as a client-bridge, so the ap and the client units were bridged together. I never had any congestion, and streaming divx, xvid, mpeg's etc from the pc through the xbox 360 is great. no network congestion what so ever.
I had a lot of headaches after buying the wireless adapter from microsoft for the xbox 360. I can tell you know, even though this adapter is dual band.. it's poop, constant network congestion, my thoughts is that it's more there for xbox live and not so much for streaming. I took back the device to harvey norman, got a refund on this adapter and kept with my two wireless buffalo-G routers, no problems ever.. Because the two units are bridged, I get strong connections of constant 54mbps, After viewing the summary of most of my avi (divx,xvid) movies and tv shows, I noticed they only require on average around 200kbps for the video stream and 200kbps for the audio stream. Meh, that's nothing.. So I stuck with my two buffalo wireless routers and I couldn't ask for anything better. As a matter of fact, it's worked so good, I went and bought another two more units and made a second AP and a second client bridge and connected my next door friend up with media center on their xbox 360. It blew me away again, the second two units were going through two double sided brick walls, over a fence, through two walls of plaster and wall studs. And spanned a distance of 35m.. Those other two units are getting a strong connection of around 34mbps, not quite 54mbps, but for what it has to go through, it's done damn good. As far as wireless and xbox 360 media extender's go, I can say these two wireless units I got are the best for the job in my opinion, and with the upgraded firmware, you can increase the mW (miliwatts) of the device to give it more juice, stronger signal, further distance. Mind you, i've been running all 4 of these units on default of 28 mW and they are still flawless.
Thought i'd edit and again make specific notification on what you need.
Two Buffalo pre-flashed wireless units. Set one up as the AP, and the other up as the Client-Bridge. Get a refund on that microsoft made xbox 360 wireless a/b/g wireless adapter.
After my recent success with Jerry at clearnet, he's doing a write up on these units and im getting some photos of my setup from my house to my next door's house, and a short write up myself. He's going to publish them soon.
*EDIT* - I'm at work at the moment, but I drew up a little plan of my current setup. Image below
