Pingplotter runs for 14 days in freebie pro mode until it locks down to a limited mode if you don't purchase a standard or pro licence.įwiw, I was able to crash a CGNM-3552 when my better half was running her corporate VPN and I was running a high rate ping test. Its actually useful to run this overnight with Pingplotter as you would see any changes that might occur between the highly loaded evening hours and no load hours after midnight. If you were to run Pingplotter, the program would generate packet loss indications on the plot which are easy to understand. ICMP was the first protocol that Intel tackled in 2016, so I know that it was resolved, but, since I don't run a CGN3ACSMR any more, I don't know if any subsequent updates have introduced any latency thru the modem as an unintentional by product. The Puma 6 modems have a history of latency thru the modem, which Intel has been working on over the course of the last two years+. You might see high time ping times on the return. If you see a much higher packet loss count, then that could be indicative of a cable and/or connector issue. Typically, you shouldn't see any more than perhaps a dozen lost packets over the course of a 24 hour test. I run 24 hour tests looking for latency, just as an example.

Let the ping run for several hours while your doing the usual internet related activities. Assuming that the modem is in Gateway mode with a direct connection, the first IP address is the modem, the second IP address is the CMTS.ģ. Run a trace to anywhere, google for example.Ģ. To check for any external cable faults you can ping the CMTS, which the modem connects to for data and control purposes. Typically the upstream runs between 36 to 40 dBmV, so your's are fine.

The upstream is just a little higher than normal but well within its allowable range. If this is a recent issue, there's a good chance that your getting very short disconnects which don't show up in the modem stats. VPNs thru the Puma 6 modems have been a pain from day one. If this has been a long standing issue, its due to Intel's firmware. This always been a problem with the VPN, or is this a recent occurrence? Are you connecting to the modem via ethernet or wifi?
