My desktop computer has been acting like it is disconnected from the internet. i can't open up0 my mail or go to any sites unless I log off and turn off the computer. I called my broadban supplier and they assured me that I was connected. Is there a setting that might have gotten changed by mistake that I could check? The broad band shows that I have internet activity but am unable to to receive or send e-mail or visit sites through my internet exployer.
