I recently moved and switched to a new ISP. Since it was hooked up, I have been having experiencing a minute or two of "Connection Reset" whenever I try to navigate to a new website. This occurs every 5-15 minutes. It occurs in both firefox and internet explorer.
I am behind my ISP's cable router, which I then plug into my own Belkin Wireless router. The computer on which I am having the issues is a laptop I run on wireless. The error also occurs when hard-wired to the belkin. I cannot reproduce it on my Asus tablet, connected wirelessly.
It mostly occurs on new websites (hinting at a DNS error), however not always (Youtube has issues loading the actual video when the rest of the page loads fine, along with others). I will also navigate to a new page on a website to see the ads replaced by the same error. I attempted changing my DNS servers to OpenDNS, but this did not alleviate the issue (I may not have properly flushed the old settings however).
I also found this pointing to a MTU error. I checked my MTU on windows 7 and the output was:
which I believe is correct.
At this point I am out of ideas as to how to fix this problem. Any ideas as to what to try next (or detailed instruction on how I should recheck something I have already done) would be greatly appreciated.
In response to Deloader's answer, I attempted to change the MTU on my Belkin Router to 1500, since a ping of 1472 to google went unfragmented. The instructions I found for doing so (shown here) changed it, but this caused me to lose internet connectivity. After a hard reset of the router, I am back where I started. I will agree that the MTU appears to be the problem, however I do not know how to change it for a dynamic connection type (which I have), since the above instructions were for a pppoe connection (which I don't have).
