I have a cable internet connection which lets my desktop connect via ethernet and my laptop to connect via a wireless router.
Recently I have not been able to connect to certain websites like www.hotmail.com, or even www.ytv.com, while other sites like this one seem to work fine. I use Mozilla firefox, and sometimes I can reach the websites on my laptop rather than the desktop or not, and sometimes I can reach them using internet explorer on the desktop as well rather than firefox.
I'm at a loss as to the cause of this, and help would be much appreciated.
