The WORST ISP there is on the planet, hands down. Should be out of business. Example below will give you an idea as to what kind of morons run the show there.
Me: "Hi, I'm having problems with my connection"
Earthlink Tech man: "I'm very sorry ma'am"
Earthlink Tech man: "Calling for tech support? You'd have better luck bleeding a stone."
Me: "I've fixed it myself"
On a more positive note..because of their uselessness I've taught myself much.
