The first suggestion: use Firefox or Internet Explorer. Any difference?
But I'm afraid it isn't the browser that resets the connection. More likely it's the router or the modem or the ISP. Does the same happen if you connect your laptop to the internet somewhere else? With a desktop it's somewhat more work to do that experiment, so then it might be replaced with "does the same happen if you connect the laptop of your friend to your connection in the same way (wired or wireless)?" as a start.
I've been getting this error for weeks now.
This webpage is not available Error code: ERR_CONNECTION_RESET
Happens across EVERY website. If I re-load the page a few times it's fine, but happens on the next page, and the next, and going backwards. arrrggghhh
So, cleaned my cookies, made sure it's allowed through the firewall, Comodo isn't picking anything nasty up. I'm lost as to what else (also uninstalled and reinstalled)
