Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out

I've been getting regular intermittent internet connection issues.  It happened months ago and I ended up replacing both my modem and my WIFI router.  Until recently it has been happening very sporadically but within the last couple of months the dropped connections has picked up.  I have a direct connection to my modem with no cable splitters but my modem does connect to a TP-Link network switch that then connects to a Philips Hue bridge, Apple TV and an EERO WIFI access point.  I've contact Comcast multiple times and the tech has done the normal reboots, and remote diagnostics with no long term success.  Below is the event log from my modem.  I know very little about this so any help would be appreciated.
