How long is your PPP connection up?
I tend to leave my system online 24/7, and have noticed that after a
time -- usually one the order of a week or two -- network performance
degrades, though I hadn't thought to trace pings. What makes you say
that they're coming in sets of 8?
My solution is also to kill the connection and redial.
