Hi Amanda,
Most of the time, the page tries to load, but doesn't finish. If it does load, I constantly get a "no internet connection" error. It sounds exactly like dianeglueck and I have the same problem. Sometimes, I can't even get onto Yahoo.com main page. I can load most any other page, but sometimes, when I click a link, it won't complete and I have to click again.
I have changed DNS settings, reset my browser (although it happens on all browsers on 2 computers). It does work on the phone, because that uses an app.
It would be very difficult to abandon my Yahoo email address. I would rather get rid of HughesNet, but it is the only thing available where I live.
