Home Network Upgrade

So over the last year, i have changed Modems 3 times, and routers. I had an order router, one I used while I was in a different location, and modem ARIS 6183, now since I upgraded (using that term lightly).  This worked on the COX network and I had zero drops. Older router also. 

Spectrum network seems to have challenges, I had an SNR problem before this modem doesn't give me the option to see for myself,  I have to take the word of Spectrum. 

As for software, I have tried what you asked, and over the course of the year it hasn't changed. I am not sure where the problem is, but I am gathering the router. 

Modem is a spectrum issued modem, since it was free, I decided to try it.  However, the problem existed prior to the upgrade, and after the upgrade there is no changes to the drops. Understand the drops have been going on for a year, while I was trying to nail down the problem. 

Essentially I concluded i have 3 maybe 4 choices - 

1. Hard wire the 2 XBOXes and leave everything else the way it is.

2. Upgrade to XR500 or higher (mesh maybe with the XR570)

3. Go mesh 100%4

4. Leave it as is and deal with it (which is an option but not one that works)

Thoughts?
