Yes I did. As soon as I did that, the wireless driver worked again, after that I installed MS Antivirus and everything worked until I updated Virus definition a couple of days ago. Just to be sure, I repeated the process today as you suggested but nothing. Just now, I also uninstalled MS Antivirus but still nothing.
I have also rebooted the wireless router twice, my other 2 laptops running XP Pro and XP Home are still running fine. I am connected to the LAN on this MSI laptop.t
Not sure what elsle to do now. Please help.
