    Just wanted to put a post here in case it helps someone in the future.  I was battling with similar ISP disconnect randomly throughout the day.  I have a Firewalla Gold with Spectrum Internet.  The same setup had been working fine for over 1 year.  The disconnect issues started a few weeks ago.  I replaced all the cables.  Spectrum came and re-terminated all the coax cables.  They said all the wiring and signal were good.  The cable modem was fine.  They even swapped out and replaced the cable modem (EN2251)  just in case.  But the problem persisted.  Finally, what fixed the issue was putting a switch between the cable modem and Firewalla Gold. (I don't remember which post but this was mentioned by someone in one of million posts I searched here and on Reddit.) Instead of connecting the Firewall Gold directly to the cable modem through an ethernet cable, I put in a 5 port Netgear switch between.  Don't know what the exact root case is as the same setup was working fine before. Possibly firmware/software changes on Firewalla?  Cable modem? BTW, a good free ping tool to help troubleshoot is called Pinginfoview.
