Wireless routers that work in place of the 100$ wirless adapter

I just spent 450$ on an xbox, and im about to spend another 50$ for 12 months of xbox live. There's no way Im about to spend another 100$ on a wireless adapter that should cost 50$

Are there any wireless routers that are known to work in place of the adapter?

if you got a laptop you can enable internet connection sharing. just run an ethernet cord between the laptop and 360.

or i bought a wireless logitech thing that connected to my router in one room and my 360 in another

get the logitech thing. i bought mine on ebay for $25.

or be like me, set up your router near your xbox and get a wired connection
