I did a shaper probe and it said something about high packet loss. I have been having intermittent connectivity issues and I've had several truck rolls. I even experimented with rental modems to rule out my purchased modem.
At least I'm getting my provisioned speeds. But I want to be 100 percent sure that I have packet loss before I waste another tech visit to have him/her say the signal is fine, we'll refer to maintenance.
Modem is a Surfboard 6120. Signals are all good Power is +3 SNR is 37 on all four downstream channels and the upstream power on both upstream channels is 40. What puzzles me is I have uncorrected codewords in the 1500 range for a modem that was reset 24 hours ago. And the log shows a T3 error code.
Setup is two 3-way splitters with the phone modem (Arris TM722) and internet modem (SB6120) on the first splitter (both on the -7.5 leg) then a MoCA trap on the -3.5 leg going to the second splitter with the two HD boxes on the -7.5 leg and the host DVR on the -3.5 leg. I do have the AnyRoom DVR. -- I've experienced ImOn (when they were McLeod USA), Mediacom, Comcast, and Time Warner. They are much better than broadcast TV.
You can't go by ShaperProbe as far as "packet loss" goes.
Why not ? It's yet another indicator of a possible problem. FWIW, every time I've had real packet loss issues either to my WAN default gateway or on the routing path to the Shaperprobe servers I got that message.
