I am also experiencing the same problem really...
I am trying to connect to the internet from my 360 via my laptop...
i am using the ethernet cable which came with the 360...
the 360 system recognises the connection between laptop and itself but i can never get beyond the IP adress stage... it never identifies the IP address... i have enabled Internet Connection Sharing on my Laptop... still no success... my laptop is connected to net via wireless router. I am running on Windows Vista Home Premium.. Any help would be much appreciated...
Thx
