Intermittent disconnects - Need to reboot cable modem then router to rectify (everyday)

Hello:

 

Current equipment:  Netgear CM1150V cable modem and Asus RT-AC88U router.

 

Eversince changing cable modems (self purchased) to the Netgear from the xfinity gateway, having connectivity issues.  When looking into the logs on the Netgear router I found the following two errors.

 

1) Unicast Maintenance Ranging - No Response received - T3 time-out

 

2) No Ranging Response received - T3 time-out

 

Rebooting both router and cable modem clears the error for approx. 24 hours.

 

Thougths?  Appreciate any guidance.  Have eliminated the router as an issue.

Were you able to resolve this? I have the same problem with my Netgear CM1150v.
