I have the same issue in the Henderson area. I've been monitoring it via PingPlotter and it happens 2-4 times an hour and seems to be the worst around noon. During these windows of packet loss, I get multiple entries in the modem's event log with 3 unique types of warnings and errors:
RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW
RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW
Started Unicast Maintenance Ranging - No Response received - T3 time-out
I have a tech scheduled to check out my installation tomorrow but I'm not having high hopes after looking at the forums.
To archive all of the modem events, I wrote a small program to poll the modem and log the events to a tab delimited file. This way I can show proof, alongside my PingPlotter data, to show the correlation incase they end up telling me there is nothing wrong or blaming my equipment.
This program was made for a Motorola MB8600 but it may work on other Motorola models. Let me know if you want a copy, I can even send you the source so that you can compile it yourself.
I have good news to report but I hope I'm not celebrating too early. My modem would log at least a couple dozen "CM-STATUS message sent. Event Type Code: 24/16" events but there hasn't been any new entries since the technician reconnect the coax yesterday. Ping plotter was clean of read for the whole night and this morning.
I was a bit disappointed when the cable tech just ran a test for packet drops. After he was done, I asked him to check for any splitters as I wanted to make sure the modem was connecting directly to the cable feed. He confirmed it was directly connected but he noticed that the grounding clip looked old so he replaced it. I didn't think much of it at the time but now I'm starting to think that may have been the culprit.
I'll continue to monitor and report back in a week.
Did you mean Event Code 16/24? It's brief noise on the circuit. If you're seeing Profile numbers, these may be of use.
I had multiple packet loss windows in the morning to a little after noon and the connection stabilized around 1:30pm. The technician arrived around ~4:10pm and I explained that the connection is currently stable while showing him the PingPlotter timeline.
The tech connected the coax from modem to his diagnostic device. After a couple minutes he told me that it's testing for packet drops. Then he says that everything checks out and that there are no problems.
My last warning after getting back online was "REG-RSP-MP Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value".
