I just bought a brand-new Dell Inspiron 1545. I started the computer, finished the registration and connected to my home wireless networking system. The Dell has Vista OS pre-loaded on it and it showed full connectivity to my internet system. However, once I clicked on Internet Explorer, the page would not load and I could surf to other pages. Thinking it was an Internet Explorer issue, I tried Firefox. Firefox allowed me to go to Google, but nothing else. I spent about an hour on the phone with Dell, who informed me that there have been some configuration problems between Vista, McAfee and Internet Explorer, but they wanted to charge me $250 for a one year software warranty (apparently my warranty is only hardware). I uninstalled the free 30-day trial McAfee but could not still surf the web. I've tried ipconfig as well as other online hints but nothing's worked. I was wondering if anyone else has run into this problem. I'm pretty close to just returning the Dell to the store and looking for another brand. Thanks in advance!
