A “pure ping” using -t switch shows no problems, but Ping Plotter shows many packet losses. What would cause that?
• The packet size could be different, and that different packet size in Ping Plotter may be causing some packet loss. Note that this is a problem with the router, not Ping Plotter, but you can change the packet size to something smaller than default to see if this affects it. Go here to see how to change the packet size. • Having multiple simultaneous outstanding ICMP echo requests may be causing a problem in one of the routers. This isn’t too uncommon, but is almost always traced back to a hub on the local side (BIOS updates often help this). See the FAQ entry above if you want Ping Plotter to do one outstanding request at a time. • In some very isolated cases, we’ve seen a difference in packet loss based on the contents of the packets. Ping -t uses a repeating sequence of “abcdefghijklmnopqurstuvw” while Ping Plotter uses repeating $AA. You can change Ping Plotter to be the same as Ping by creating a text file with the same thing that PING sends (i.e.: create the file with abcdefghij
