The problem is this. i unpluged the ethernet cable from my desktop running xp pluged it to my laptop windwos7 and it searches for like a minute to only gives me the unidentified network no internet acces message. HOW CAN IT WORK IN ONE machine and not in other? i have uninstalled the divers and isntalled it back even upgraded and the worst is that i take that laptop and pl;ug it with a cable in my friends house and bang! it works.. i have done all the toubleshooting steps from the microsoft page and it is still not working , disable ipv6 also , enabled it back again. what am i missing?
