Occassional Internet Loss - RBR20

I am trying to track down a nuisance connectivity issue.  I occasionally encounter loss of connection for typically a few seconds (1 - 20 seconds).  Normally this wouldn't be an issue, however it's a pain when I'm connected to my work through a VPN and it drops upon a slight loss in internet.  

My computer is connected wirelessly to the RBR20 router.  I've got two wireless satellites and one hardwired satellite.  

I show that there are about 20 different devices connected to the orbi system.  Most are minor devices (Ring doorbell cameras, etc.).  I don't have any complaint about speed (ATT fiber - 300MB).

I contacted ATT and they said that there hasn't been any connection issue to their smarthub in a couple of months and supposedly they see on a second by second basis.  

ATT suggested that I reach out to Mesh community as they don't see a problem on their side.  

I downloaded an Internet Connection Monitor extension in Chrome, i've attached the log to this post.

I am unsure if the connectivity is a concern without being connected to the VPN as I probably wouldn't recognize the loss of connection for a few seconds depending on what I was doing.  I do occasionally run into loss of internet on smart TV's so I'm assuming that the random connection is routinely occurring.

NOTE - this log would only be valid when I have my work computer connected to home network, so I'd guess that the connection concern is a whole lot worse than I am showing.

Any suggestions on what to look for or settings to change?  The connection shows full strength.
