I need to ping mulitple target that are connected via cellular 1xrtt connection. I need to simulate a 500byte packet at a rate of once per second. I set my ping interval to 1 second and set my interval between targets in the options section to 50 ms. I have approximately 20 hosts I need to ping every second. but I am getting a lot of N/A's in the logs. I have setup alerts to always right to a log file. Can anyone give me an example of what settings I need to make to get this to work well. I wouldn't think a PC would have trouble sending out 20 500byte packets per secondso I figure I must have something set incorrectly. Latency on these links are typically 500ms-1500ms depending on geographic location.
