I did that morning, I've done networking before for my college IT dept when I was an undergrad.
Anywho, I still have issues from time to time, like right now - more in a sec, but somehow while on the phone with them that morning it seemed to miraculously fix itself...
This is what is coming in right now both plugged to the router, and directly to the modem. I also ran ping tests from the router itself out, so the only thing between the connection to the net was the modem.
I know its like 2130, and "peak" hours, but there is no reason for a ping of 400, and CERTAINLY no reason for a ping of 800.
