I am on vacation at a residence that has a cable modem. Windows XP connects
to the internet with no problem, but I can not get Vista to connect.
When I connect the Vista laptop to the ethernet connection on the cable
modem, and click on Internet Explorer it lets me know that I am working
offline. I click on the network icon in the task bar, and the Network and
Sharing Center opens up. there is a red "X" on the line between
"Unidentified Network" and "Internet." I click on the Red "X" and Windows
Network Diagnostics comes up. The 3 options that it gives me are no help.
I have had this laptop for a few months and it was working fine when I left
home yesterday. It is normally connected to a router, along with 2 other
computers, and the router is connected to the internet.
Thanks for your help!!!!!
