The specified IP address must be running Iperf in Server mode (if the remote modem does not have the Iperf server
running then you will get the following Error message on the web page,

you look at the modules you will see the TX/Link & RX Led‘s flashing very fast as it performs the test. Approximately
10 seconds later a graph showing the actual throughput over the 10 second period and a calculated average will be
displayed. The graph below shows the data throughput range between 8 and 14.5Mbits per second with an overall
average of 10.9Mbits per second. It is recommended to perform this throughput test a number of times to get better
sample of the overall throughput.
The expected throughput will depend on a number of things, the distance setting, selected channel width, and whether
using the internal Iperf utility or running Iperf externally on a laptop or PC (at both ends of the link). The following
table shows the estimated throughput results based on real world communications. These estimates are not necessarily
the maximum that are achievable in the modems but are used more as a guideline to determine the performance of the
radio link. The Iperf throughput result provides an excellent measure of the performance of a radio link. In general, if
the results you get are a lot worse than the best case values listed below, this is a certain indication that the radio link
has either poor RSSI, or high noise or interference, or both.
