c7000v2 resets
I am getting frequent modem resets.
The event log states:"Received Response to Broadcast Maintenance Request. But no Unicast Maintenance opportunities received. T4 time out, CM MAC=38.94 ed: dd:f4:c8:CMTS-MAC=f8:b7:e2:05:99:ce:CM. QOS=1.1:CM.VER=3.0"
Firmware version. V1.03.01
Does anyone know what this means?
Do I have a defective modem?
You're power levels are out of spec. They should be within 3.5dbmv of each other. Yours goes from 4.3dbmv to 10.7dbmv. A 6.5dbmv difference. a little variation is fine but that's quite far.
If they're saying the lines fine, maybe it is indeed a modem issue. You can always try renting a modem from the ISP for a month. If it works fine, it could be the modem. If there's issues, then the ISP can't blame the modem.
It could also be that the ISP gave you a docsis 3.1 device which is a little more tolerant of power fluctuations/levels.

do you have a screensnip of the cable connections page and the full logs?
That helps more than the 1 error notice.
Let me know if this works
you only got about 8 channels of the cable connections page.
But you have a bunch of errors in the logs. Those tend to be line issues.
Check the line for kinks, damage, loose/cheap connectors, extended runs, etc. Move the modem to right where the coax enters the home.
If it already is and the line's fine, then the isp needs to check the line.
