Hi, I've had this problem since first installing win7 and its been killing me . I'm using Windows 7 Home 32 bit. My setup is 2 network cards (no router); the 1st connected to my cable modem, the 2nd directly to my Xbox (using Cat5 cable). I turned on Internet Connection Sharing, made sure my firewall was good, even changed cables, still nothing. Also, when i turn on my Xbox, the Xbox connection comes up as "Unidentified network". Any help would be greatly appreciated.
