C7000v2 disconnects every 2 hours

[rbacon277]

Was there ever a resolution to this issue?  I have been experiencing the same issue.  My internet service drops every two hours for a few minutes and then it clears up.  I'm seeing the same errors:

Warning (5) MMD message timeout;...

Critical (3).  Started Unicast Maintenance Ranging - No Response received - T3 time-out;...

My service provider has been out twice to check all the connections and the signal strength, but they have not been able to find an issue.  I even rewired my modem to be closer to where my service comes into the house.   I installed my modem in late March and experienced the issue about a week after installation.  It cleared up for a few weeks, but then it started happening again last week. 

Thanks

Thank you Furrye38.  It must have been something on the ISP side as you suggested because the issue and errors cleared up yesterday at 13:42:41.  I'll let you know if they resume at some point.  I don't want to waste your time chasing ghosts.  I really appreciate your willingness to help.

In most cases it is on the ISP side. Glad something got cleared up. 

Come back if you need more help or other information.

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
