hi i have three PCs 2 vista 1 windows 7. the vista machines both have ipv6 local, the windows 7 machine says no internet access or no network access. does anyone know how to fix? the internet gets as sloww as dial up and then i reset the cable modem which fixes it. then it happens again. i suspect theres either a problem with my network adapter on the w7 machine or it isnt ipv6 ready. its a broadcom from dell if that helps.
