Started Unicast Maintenance Ranging - No Response received - T3 time-out

I have Xfinity Maintenance coming over but, after looking through this forum, it appears I might have an issue the tech can't diagnose. I believe I've included the necessary logs for diagnosis along with redacting MAC Addresses. I've been working on intermittent service since Tuesday and changing out the modem/router for a new one (same model) didn't help. I've also talked to Support Multiple times so I've gone through the checklists... cycling power, checking connections, etc... multiple times. Although my wife works from home I believe our data use is fairly normal (I see that Xfinity have asked others posters if they're gamers). Any help would be appreciated. 

My Modem/Router is a Netgear AC 19000 C7000V2

The tech was helpful in verifying and replacing some hardware outside our condo but he didn’t look at my forum post or data points when I pulled up the data. He took his time and changed out some old splitters which was useful even though he couldn’t get it to work.

Since I had two modems (one brand new and one older that were the exact model and software version) I found it strange that he thought it was a modem issue. The older modem/router has worked perfectly for years. But when he hooked the cable to an Xfinity Gateway it worked.

Since I’ve been with Comcast/Xfinity Internet since they were @Home I’m not about to rent a Gateway for the rest of my life so I’ve taken your advice and bought a seperate modem and router. If I have the issues with the Arris S33 I’ll update the forum with another post. But my wife has gone a work week without stable internet and we have no backup for her work computer. So, unfortunately, I don’t have time to work through the Netgear AC1900 C7000V2 issue. My marriage is at stake.

Thank you for taking the time to reply to my post and all the posts that helped me understand the possible issues. You’re invaluable to this forum.
