Ok I just recently changed isp this afternoon. I show full connectivity, I'm sending and receiving data, I can ping websites and have no loss in packets. But all browsers I use can do nothing (IE, Chrome, Firefox). I've tried many things; dns flush, system restore, clearing prior settings, disabling Norton and Windows defender, the
netsh int ip reset resetlog.txt cmd. I can't even remember everything I've tried. I'm connected wirelessly, using Windows 7 on a hp pavilion elite hope. My new isp is xfinity(comcast). The best results I've seen is with the system restore, I got 2-4min of browsing. I had my laptop right next to pc and it works fine. Also everything in the house connected wirelessly works fine. I'm at a loss and have no clue what to do.

Did you change the ISP but kept the old router?

Now in case you still haven't fixed it, it would be easier to call tech support
