In need of wireless acesspoint(?) router

[FeFiDoh]

Suppose it can go in here if not sorry!

Basically the router is downstairs connected to the phone line i have my PC/xbox/xbox360 upstairs i could do with a wireless kinda of access point that can connect to my router downstairs so i can get internet to my xbox without the PC being on. At the mo im ICS them both and have to keep swapping cat 5 cables over!

What can i use?

Wireless ethernet bridge, however you need to buy a special (overpriced) xbox 360 one iirc

Wy do you have to keep swapping yer cables.
I have a similar setup to you only my X360 is downstairs. My router is connected to my main rig upstairs via ethernet, the X360 is connected by ethernet downstairs and I use my laptop wirelessly.
You never need to turn yer PC on for Xbox live.
Am I missing someit

Edit:
Just realised I am assuming you dont want cables running, X360 bridge you need.
