I am having an issue with my Dell Inspiron 6400. I can't connect to the internet. Well actually My network thing shows me as connected and if I use the wireless connection it also shows that I am connected. But when I open any Browser to any page it says, What is very strange is that I can use Thunderbird and get my email with no problem. Only with any browser (IE, Firefox, Opera or Chrome) that I open and try to connect to any web site. Now this occurred back in December but I had put away my Laptop and had not used it or tried to use it until last week. I used Malwarebytes and AVG to see if I had any issues, and nothing. No viruses no trojans no nothing, squeaky clean. Now I do remember doing a Windows XP update a few days before this all started. I checked the windows firewall settings and they seem proper, also did the winsock fix and nothing. I also did the IP release thing (I think that's what it's called) and that didn't help either. I also turned off Windows Firewall and that didn't help either. So all you network Internet connection geniuses out there, HELP! System is XP home with SP3 Intel Centrino Duo, AVG Antivirus & Windows Firewall is active atm.
