Ping and Traceroute testing

The Ping test sends a ping packet through the modem to an IP
address or DNS name (could be a network switch or web address)
to test for connectivity.
The Traceroute test sends a packet through the modem to an IP
address or DNS name (could be a network switch or web address),
then traces each hop from the source (your instrument) to its
destination. When running the application, the response time and
hops traversed by the packet appear on the Traceroute screen.
Once you have your profile setup through Profile Manager, you
can run the test. Make sure the test is enabled in the profile, as
well.

Speedtest by Ookla data testing

Speedtest is used to test servers all over the world. It determines
the server name and checks downstream and upstream
throughput via the test interfaces. Its download/upload rate is up
to 2 Gbps for Ethernet. Speedtest uses any IP interface, including
IPv4, that you established for testing. It does not require any
additional configuring.

Before you begin

Once you have your profile setup through Profile Manager, you
can run the test. Make sure the test is enabled in the profile, as
well.
The Speedtest application will require you to accept the Terms
of Use before allowing to proceed. The Terms of Use must be
accepted every thirty to ninety days.

Latency measurement

The unit will ping the Speedtest server the number of times specified in the Speedtest
configuration. The pings occur at whole millisecond intervals slightly greater than the
server connection phase's latency measurement. For example, if the server connection
phase's latency measurement for the server was 3.2 milliseconds, then the ping intervals
will occur at 4 milliseconds. An average ping delay value and a ping delay jitter value
(both in milliseconds) are provided for each ping. The final ping average result (in
milliseconds) is then derived.
