I have 2 wireless routers, can I connect 1 to me sons xbox360

I have a netgear router(sky) connected downstairs this is my connection to the internet. I also have a bt home hub spare can I configer the bt hub to access the sky router so my son can connect to 360 live. I know I can use a cable but I dont want to use that option as i would need about 20mtrs.

thanks
