I just made the switch from xp to win 7 ultimate (64) and everything is working great exept the Internet, inside my computer I have a dlink DGE-530t I installed the driver on the cd, I also have a cable modem from videotron plugged in a dlink wireless router (with good Windows 7 64 bit driver!
Windows can't establish a connection "invalid ip adress" 3 hours ago that setup worked flawlessly under Xp and the funny thing is my Internet works just fine! I'm writing this on my iPhone via my own wifi !!!
I hope someone will help me, thank you
