Was it slow on your DSL setup? If it wasn't then it may be the fact that
their DNS servers are just overloaded and slow to respond. I've seen
this quite a lot with different providers. I also saw it with my
company since we are a telco/ISP. We had our DNS servers on some slow
machines 4x450 E420's (2 machines) and they were ok..but a bit slow. But
then myself and a co-worker rebuilt the machines using Sunfire v210's
and things zoom along now. It may not be anything you did ..that is if
your DSL wasn't slow but the cable is. Also, remember that one of the
drawbacks of cable is that you're on a grid with other users. I don't
know that cable has overcome the problem of " the more users on the
grid, the slower the connection " which cable use to suffer from.

Since your on XP try doing some traceroutes and what not to see if there
is packet loss and what your response times are.
