This wont work for me because it's not any particular site I can't access. It's a complete internet connection failure because the cable, send, and receive lights on my modem are off (when this happens). As mentioned, I perform all the obligatory tests, reboot my modem & computer, etc., etc. When I click on my Firefox icon, the page tries to load then I get the error message "problem loading page". Then I try try accessing the internet via Internet Explorer, same thing.
It doesn't happen often but when it does I want to be able to know that I should either a) call Cox Tech Support or b) fiddle with it on my own because it's something on my end.
Thanks for the info though.
