Co-located Gemini Apparent Network Instability

We've had our Genie (HR44-700) for several years on a wired ethernet connection without a lick of connection trouble.  The location of our Genie has always been in a less-than-good wifi location in our house so wired has always been the way to go.

I got a Gemini (C71KW-400) earlier this year as part of a promotional deal; I finally decided last week to try it out.  I connected it via the co-locate instructions in the box, flipped over to a wifi connection, and crossed my fingers.  Everything seemed to work fine at first.  Connection was solid, and Speed Test achieved the fastest speeds available.  However, now that I am forced to Wifi, I am seeing some occasional connection issues.  I ran through the Wifi set up for my SSID, and things connected well via speed test and such.

The first thing we noticed was that sometimes, we'll be watching something on Netflix on the Gemini and the connection will drop after about 5 minutes or so.  We flip over to the Netflix app on our smart TV or Roku, and Netflix works 100% fine there all the time.

Sometimes when I run speed test, it looks to re-configure the connection as if it's not even configured.  Other times when I run a Speed Test, it says I have an internet connection, but cannot run a Speed Check right now.  Other times, the Speed Test comes back just fine at the max available.  All three of these scenarios happen seemingly randomly without any re-entering of network details on my part. The connectivity icon at the top left flips from network to no network during these times as well.

Being an IT geek by trade for over 25 years, i started looking at things on the network level.

I see that my Genie and Gemini both have their own connection to my Wifi mesh network with their own IP addresses.  If I run pings against both of those addresses from my router, roughly half of the packets get dropped, and performance is not the best.  Perhaps that is expected from pings to these devices, I do not know.

I then tried a full factory reset of the Gemini to clear out any possible mistakes I had made in its initial setup.  Got it back up on its feet, connected to my network, and fired up Netflix.

When streaming on Netflix, the playback stopped for about 10 seconds roughly every 10-15 minutes.  One time, it stopped completely, and I had to quit Netflix and reconfigure the Gemini's network to get going again. During this time, my router was showing a very strong connection to the Gemini (ranging between -45 dBm and -50 dBm), and the connection timer on the router is not resetting.  In addition, Netflix was unable to advance to the next episode without reporting a full network failure, necessitating a restart of Netflix and needing to reset my Gemini's network configs.

So, I'm at a loss at this point.  I love the Gemini's "one stop shopping" for all my entertainment needs in this room.  However, if I cannot stabilize the Wifi, I may as well go back to just the HR44 Genie on a hard line.  

Does anyone know of a way to use a wired ethernet connection with a co-located Gemini?  Or have any other ideas as to what might be causing my issues?
