Diagnosing 2% Packet Loss

2%, 3% loss over what time period? Personally, I'm against the use of a ping as a tool to diagnose anything other than a connectivity issue, I've seen far too many people, professionals included, in a futile search fro problems that they perceive exist because of the way they use the tool. Worrying about 2~3% packet loss across the internet, where you have no control, of the route the traffic takes, and no idea of what's going on along that route is nothing more an exercise in futility. Ping the inside interface of your router - if you have packet loss - that is inside your network, you can find the cause & fix it, ping the external interface of your router (be very careful here if you have a dynamic address, as it may change), if you have packet loss to the external interface that is not present to the internal interface, you may want to take a closer look at what the router is doing. One caution - note I said packet loss - you can expect to see variations in the response times, as far as the router is concerned, responding to ping requests is not a matter of urgency, and does not receive a high priority, it will reply when it can, and if you get a time out (which will be shown as packet loss) because of that, as far as the router is concerned - tough luck, try again later.
