I have 2 Dell towers on a DLink router and a Lenovo laptop which connects wirelessly. Today I tried to open IE 8 on my laptop and it could not find my home page. When I remote to one of the towers, I was fine and could get to the Internet but not from the laptop. I even booted into safe mode with networking but it still couldn't connect to Yahoo. I even tried loading Firefox but that didn't help either. BUT if I put in an external IP address of a dvr, I was able to connect and see the cameras in operation. What's wrong with my IE?
