Are all RBR750s defective?

Just to be clear, I bought the Orbi RBK753 because of the almost universal constant that the Orbi 782's get great reviews, and instead of getting great reviews quality service out of their slighly less amazxing, I have burned over 30 hours of my life trying to get them to work over a near month long period of time. I am angry and I think rightly so. So, do not take my anger personally, unless you are a Netgear employee.

Before I go through this kind of alteration to my work at home network that also is required to keep my kid's educations going, can you answer me one question...

If I take this Orbi 753 system out to the desert, 5 miles from the nearest anything, having 3 inverters connected to solar panels to power them up where I place them exactly 25 feet apart in well ventilated electromagnetically transparent tents where they are kept cool enough to function, starting up the 2 satellites first at the outer sides and having the base router unit in the center powered up last, Should I have a problem connecting to them with my Galaxy S8 plus?

I ask this because it seems that people are not understanding where the problem is with this unit or all of the units I have gotten so far.

It is not an internet connection problem! period!

The first problem is that my phones will not easily connect to a brand new unit wirelessly. This includes the following phones. My personal Galaxy S8 plus, my daughter's Galaxy S10 plus and my wife's Galaxy Note 10 Plus. What does my ISP or the Modem have to do with this? Even unplugged from any ethernet cables, this thing should function as a wireless router, no? If i click on any other network, even at walmart, lowes, home depot, or AT&T at home and click connect, it starts to connect, and then is connected. If I try to connect to Orbi##, it will say it is trying to connect, then nothing, then trying to connect, then nothing, then trying to connect, then nothing, then trying to connect and if I am lucky, it will then say something about evaluating the quality of the connection, and then connected. When I go to check my connection quality, it is always 173 Mbps. These Orbi Routers are the only devices that I have this specific connection quality limit on. 

The second problem is that it constantly fails to aunthenticate my login credentials, even after having been connected. I seriously doubt that my ISP or the modem/router I connect to them through is causing this problem either. I do not think my phone is sending bad credentials.

The third problem is that at 6 feet, I should have a fast and stable connection to the WiFi. Instead my Galaxy S8 plus that can connect to the BGW210 at 866 Mbps when it is in the other room behind a wall cannot connect to the Orbi router base unit any faster than 173 Mbps. It then has half life measured in seconds rather than hours or days.

It has nothing to do with the technology in general. If I go upstairs to where the satellite is, I assume the satellites use the same WiFi technology as the base unit, I will get a 650 Mbps WiFi connection through Orbi, my wife's Galaxy note 10 Plus occassionally exceeds the gigabit spped. If I then check my internet speed, I will get a good proportion of that connection speed as internet throughput.
