I've been a PingPlotter user since 2003, but I have not needed it often, which is a good thing. Just recently, I bought a Netger WNR3500 router. Things seem sluggish, although tests through http://www.speedtest.net do not indicate any problems, most of the time.

There are lots of configuration options in the Netgear that I don't understand, such as SPI and Open NAT Filtering. Therefore, I cannot tell what is going on. Take a look at the capture below. The only way I could get rid of the red was to turn off SPI, which Netgear says should not be done. Even then, the various hops show high packet loss, which doesn't show up in the total at the bottom.

It's possible that the WNR3500 is doing what it is supposed to do, but if it is, PingPlotter is not of much use. Please suggest what I need to do before I decide to try another brand of router.
