I have RoadRunner. I called to complain that my bill was too high and
they said that I could get the same service, but resold through
Earthlink. Earthlink bought Mindspring a while back, so I guess the
DNS is all mixed up.
Anyway, I switched back to RoadRunner because they now offer a service
that's cheaper than Earthlink.
Does'nt explain the slowness, but no need to worry. It's all on the
same layer2 network, since I've had the same modem ever since I was
hooked up several years ago.
