Your levels are teetering on
unacceptable, you probably have some issue with the cable.
Phx sucks for heat, you get what is known as "suck-out", literally
the expansion of contraction of copper over time with our extreme
heat and cold causes this to happen over time pulling the
conductor out of the middle of the connection, shrinking it. I
have it occur about every 5-6 years in my house with the run form
the ped (pedestal, where the tap into the main coax is back to the
node). Never inside, but from your street drop to your house,
where it branches off internally usually.
Call cox and complain until they send someone to replace your
external line. Ask if your neighbors are having issues, if you
talk to your neighbors (I'm anti-social, I usually figure it out
because I've worked in cable systems for years and used to it),
might be a node issue.
If you get someone with a clue at cox, you can ask them to check
across your downstream interfaces if multiple people are having
issues with disconnects or cmts reset errors. The modem reboots
when levels get too far outta wack.
Biggest issue for Cox seems these days for residential service,
they send you for support queues to someone in the Ozarks among
hillbillies now that can barely speak english let alone tell you
what levels or nodes mean. The joys of consolidation and
insourcing (as it was for Cox, decided by idiots that should have
been fired 20-30 years ago to build their call centers in the
un-technologically inclined regions of the United States).

I have a 1-3 year old Motorola Surfboard SB6141 and
Cox. The modem and my LAN are up 24/7. Recently, I have been
loosing my connection to the Internet. My local LAN is up (I can
ping/ssh other computers on the LAN) but I get and error message
of "Can't resolve host" when I try to ping google. A quick power
off, wait 30 seconds, power on of the modem fixes the problem.
These outages are happening more frequently - daily for the last
two days. The lights on the front of the modem are not different
between running normally and unable to access the Internet.
The downstream signal to noise is 37 - 38 dB @ 14
dBmV. The upstream power level is 41 - 45 dBmV.
I am seeing this in the logs for the modem on a
regular basis after the reboots
MIMO Event MIMO: Stored MIMO=-1 post cfg file
MIMO=-1;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0;
TLV-11 - unrecognized
OID;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0;
Do I need to buy a new modem? Is there anything Cox
can do?
Thanks,
Mark
