Persistent Connection Drops - DHCPv6 Missing Required Option 82 and 24

Background: We have had 3 technicians out. The first one came and replaced my 1.5 year old XB7 with an another XB7 about 2 months ago. The second one removed all the splitters and now I'm on a single line from the pole to the modem (this was about 3 weeks ago). He said the signal strength improved dramatically, but the issue persisted. The 3rd one came 2 days ago, and basically said everything looked good from his end and I should get another WiFi router as the XB7 isn't great at WiFi -- which I went ahead and invested in an Eero. As you'll see below that did not help either.

Problem: The critical problem is that the internet drops every couple of hours. What do I mean? All my iOS devices, my computers, my Roku, my Xfinity home cameras -- all go offline. I have to then go and manually reset the XB7 (remove power cable, wait 30 seconds and replug). It mostly comes back but obviously it's not sustainable for me to keep doing this multiple times a day. It does not matter whether I use the Eero or the WiFi from the XB7.

What I have tried so far:

1. Removed all splitters and now a single line from pole to modem

2. Switched 1.5 year old XB7 for a brand new one

3. Tested WiFi with both just the Eero and with just the XB7 

4. I followed this thread and unchecked the "Stateless" option under 'Local IP Network' settings as recommended here: https://forums.xfinity.com/conversations/your-home-network/symptom-cannot-reach-url-dhcpv6-missing-option-24-and-option-82-persistent-cable-model-event-error-logs/622cf2e26c4cd02237d454e5

-- That did NOT work for me

What I am hoping for:

The only hope at this point seems to be what this thread recommends here: https://forums.xfinity.com/conversations/your-home-network/frequent-internet-interruptions/6310ed9ee951e801ff0ac14e

It sounds like @kbayer22 got a technician to reset some setting on the Xfinity end. Specifically: "The DHCP error will not occur anymore" I asked if they just troubleshot it or if they actually made a settings change and his response was "DHCP may fail to configure the client in proper way, It can't communicate with any server and you will loose the internet connection for a while and then it gets back on. That was reset from our end."

Ask: Can @XfinitySara or someone from Comcast please help me with this ask? 

Thank you!
