Use the iPerf service
Your AnywhereUSB Plus device includes an iPerf3 server that you can use to test the performance of
your network.
iPerf3 is a command-line tool that measures the maximum network throughput an interface can
handle. This is useful when diagnosing network speed issues, to determine, for example, whether a
cellular connection is providing expected throughput.
The AnywhereUSB Plus implementation of iPerf3 supports testing with both TCP and UDP.
Note Using iPerf clients that are at a version earlier than iPerf3 to connect to the AnywhereUSB Plus
device's iPerf3 server may result in unpredictable results. As a result, Digi recommends using an iPerf
client at version 3 or newer to connect to the AnywhereUSB Plus device's iPerf3 server.
