Anyone use ethernet instead of wifi on their Nest Hub Max or 2nd gen?

[sneak]

I have both Nest Hub Max and 2nd gen. 
I can't get either to work with ethernet for the life of me.

I've tried 13 different ethernet to micro usb adapters.

Setup won't complete without asking me for wifi when the ethernet is plugged in.

And if i plug ethernet in and reboot the hub, it gets stuck in the start screen where four colored circles circle each other apparently till the end of time or until I unplug the micro usb ethernet adapter.

Google Nest Hubs require Wi-Fi in order to work.

When you say you "plug ethernet in", what exactly are you doing? Our Nest Hubs and Nest Hub Max do NOT have any port where an ethernet cable or a micro USB cable can be plugged in.

Both my Nest Hub Max and Next Hub 2nd gen have micro usb ports at the bottom.

To gain access, I had to detach the base. 

Maybe yours doesn't have a micro usb port, but for those that have one like mine; I'd like to know if you were able to get ethernet to work using this micro usb port. And if so, what did you do to get it to work?

I've never tried removing the base on any of our Nest Hubs to find this micro-USB port. But I highly doubt that this hidden micro-USB port supports a totally undocumented secret Ethernet interface capability.

I found these 4-year-old posts on Reddit where customers speculated the port is a "flash protocol so Google can diagnose them" or "mostly for diagnostics and/or loading firmware during the manufacturing process":

And there's this 2-year-old post on ARStechnica:

"The Home Hub holds one other oddity: if you're a tinkerer, you can pop the rubber base off with a slotted screwdriver, revealing a hidden Micro USB port! The original Google Home came with a Micro USB port, too, but just like on the Home Hub, it was only used "for service," according to Google."

And there's this 2-year-old post on the XDA forums, claiming the micro-USB port is used to flash the operating system onto the Nest Hub:

Hey everyone,

Sorry for the late response here. I appreciate @MplsCustomer for providing helpful insights. I can confirm that the micro-USB port located on the back of Google Home and Nest speakers or displays is intended for service use only.

We are always looking for ways to improve our products and services. If you have any further comments or suggestions, you can also share them with us by saying "Hey Google, send feedback" on your device. For additional steps, please refer to this link on our help center.
