Intermittent Internet Drops

Quite a bit of troubleshooting. Some history. 
In May, switched to use modem/router combo: Arris S33v2/TP-Link AX3000 combo. S33 activated easily using the app and was stable until about mid to late July when disconnects began.
Troubleshooting
 - usual re-start/recycle/power-off/on attempts
 - checked connections; checked for splitters
 - tried connecting using different jacks in house/capping others
 - disconnect cables/cap outputs in outside amplifier  so only a single cable is in use
 - bypass outside amplifier and in-house cabling with/direct RG6 coax run from outside post-MoCA filter to modem
 - rented a gateway from Xfinity on 9/17, through house connection as well as direct from outside to gateway

Disconnects still happen daily. Frequently in the morning and night. Intermittent mid-day.

Awesome. It sounds like you've gone through all the steps already. We can check a few additional things and have a tech out to further assist if needed. Please send our team a direct message with your full name and address.

@EG​ Wow that self-help checklist you linked to is pretty technical, if we're not techies/engineers it really is too much, quite crazy to expect regular customers to do all that - and even understand it.

Service rep, a super-nice guy, was out on Thursday, 9/26. He said he ran tests prior to his arrival and suspected he knew what the issue was before arriving expecting to find an amplifier in place. Said too much signal to the house and was showing 500+ "resets".  Also mentioned the amplifier may have been overheating. He removed the amplifier,  replaced the MoCA filter saying it was an older "version" that was also showing some corrosion, and installed a new splitter in the box outside. His testing showed signal levels were way better afterwards.

Equipment in use during visit was xFi Gateway and we did not notice any disconnects/resets the rest of Thursday and all of Friday. 

This morning, Sat 9/28, switched equipment back to s33v2/AX3000 hardware. Will report back after a day or so.

Connection has been stable after switching back to owned equipment on Saturday, 9/28.

@user_6fo143 Thanks for sharing the resolution here with our community.

great to hear someone got a good technician visit and possibly has had the problem fixed. Fingers crossed
