WAN accessibility cut-out at 18:01 MT every night

Any progress on this? 

What NG product model are you referring too?

• An ISP (xfinity) service tech checked and confirmed the signal and line quality UP to the modem is in spec.
• An ISP service tech re-provisioned the modem.
• Per the ISP service tech there are no line splitters, amps, or attenuators between the modem and ISP service box.
• Two different ISP service techs separately replaced the RG6 coax cable up to the modem.
• The cable is in-wall; so, there is no way to check for kinks, damage, or moisture in the line (other than checking signal levels).
• The ISP service techs checked the connector ends.
• I have disconnected the modem from the power for over 1 minute and powered back on with no change in the symptomology.

 

Let me note again three salient aspects of this failure:

* The cut-off occurs regularly at a very specific time (18:01 MT) each PM. Over the last several days I've confirmed that the AM cut-off occurs regularly at 6:00 MT (i.e., no mail from icloud or my business server is received after 6:00 AM MT); and

* The cut-out is only partial: the xfinity web site is accessible, and generally (but not always) google is accessible. Sometimes a few other web sites (e.g., local community newspaper) remain accessible; however, almost all others - including biggies (nytimes.com, washingtonpost.com) - time-out; 

* Prior to my changing DNS servers I was unable to recover WAN connectivity, with or without a modem reboot, until morning (generally between 8:00 - 9:00) when a modem reboot would recover WAN connectivity. After changing DNS servers I am generally able to recover connectivity after a modem reboot.

 

While appreciated, generic suggestions that do not recognize or acknowledge the particular details of the failure I'm experiencing - especially those highlighted above - are unlikely to be helpful.
