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.
