Ok, so my internet will cut off and the like yellow exclamation mark triangle will pop up. I click on the red x in the network and sharing center to troubleshoot the problem and the internet connection comes back, but I can only load 1 or 2 pages and the whole thing happens again over and over. Most of the time it just says it can't find a problem, but ever 4 or 5 times it will says DNS server not responding. Is this an ISP problem? I have Microsoft security essentials running and have tried shutting off the firewall which didn't help.
This started happening a couple days ago out of the blue, help would be appreciated.
