Okay well i have wireless internet on my labtop. i need to to know if u can get a ethernet cable, connect it to ur 360 and labtop and use the Wireless siginal to my 360.
i doubt it
my 360 is connected to a router which is connected to bothe my cpu and the modem so now i have an internet connection on both
i would suggest getting the exensive (but so-not worth it) wireless adapter thing for the 360, costs about $100 and the internet connection is pretty bad, but thats only if u want a wireless connection
thats all i got
hope that helps
