DNS wierdness and cox communications

[Matrix Mole]

I'd say it's guaranteed cox. I'm having exact same problems and cox is
the only provider involved. I've a fried who lives about two streets
over from me, again having the same problems. Unfortunately, I've
called cox and they basically are telling me it's my computer (all 7
of them in my house) that are at fault, cause nothing on their network
could cause that behavior. When I mentioned to them that others I've
heard of were having these problems they were like "Oh, if that were
the case we'd have a lot more calls, and we don't" then they dismissed
me. I'm calling back tomorrow and going to talk to a manager and see
if maybe I can get someone to accept they've screwed something up in
their network and need to fix it.
