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

[jwellner4]

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.
