My mb8611 modem keeps rebooting even after the tech replaced all of the ends.
I have the Motorola mb8611 modem and it has been rebooting like every couple hours a day. A Comcast tech came out yesterday and replaced all of the ends. 1 end had suckout. After that I got my best speeds and for a few hours, it was great and then I lost connection. I check the modem online it listed that the modem was up 3 mins.
I looked last night and saw this. Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received.
I woke up this morning and it had rebooted again with an uptime of about 4 mins.

The downstream SNR's are too low. And they are completely out of spec on channels 1 through 8. As you can see there are uncorrectable bit errors on those channels. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.
Since you had a tech visit you may want to get them involved again until it gets fixed properly.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.
Good luck !

I am having a similar issue with my MB8611. I have had three techs out, a new line run to my home AND did a warranty replacement on the 8611. It seems to be an issue with firmware or something else as I've had the same issue with two modems. I get frequent T3 timesouts, and the modem reboots itself. If I plug my old MB8600 back in, it will stay connected for months.
