Sorry I've not responded till now. I'm still at times not able to connect to the internet. Now as to all of the suggestions that you guys have given me,
Patonb's and
Yard Dog, still having connection problems. In fact while I am typing this reply, I had to wait because Firefox lost the internet connection for a minute. And when I than try to connect to I.E. I get this message; " Internet Explorer cannot display webpage". I hit the suggested message displayed "Diagnose Connection Problem" I get another message that says "Windows found a problem that cannot be repaired automatically connect internet provider". BTW I wanted to tell you I'm using a Cisco Valet Connector trying to connect to our Cisco 1000 Wireless Adapter. It use to work but than last week it started having issues that we have already addressed.
I'm ready to go and buy
Windows 7 and get rid of Vista. I hate the expense but I'm at my wits-end.
