My original post may not have been clear enough but my pings are once per minute in my list. So connectivity comes and goes over periods of ~5 minutes. Your ping list seems to be a standard once per second ping so it only covers less than a minute. Out of curiosity, what chip is used on your Intel NIC? My original question of how to debug this issue remains. /Morgan
