Many revisions later my new WiFi Network Hotspot homebrew system has been updated.
UPDATE 2021-01-08
The powered USB hub will not charge my S6 Tab nor S20 Note Ultra, it will charge and keep the M2000 at 100%. That works because I would only use the tab or note USB tether if all three mifi/usb mobile internet connections does not work. I still havent been able to utilize all of this bandwidth through the network when tetherd…

I need reliable coverage while on the road and having one cellular provider wasn’t going to cut it. With my current setup, I could lose service from two providers but if I still had one, my wireless connection to the internet wouldn’t skip a beat.
Yes, I have Wi-Fi 6 in my Toyota Prius!
Wi-Fi 6 is fast, very fast Wi-Fi with great coverage when I Overland!
My solution has multiple cellular modems all connected through a router that balances the load between all of the modems.
I recently purchased a 3 USB Charger Socket Power Outlet Fast Charger and installed but once or twice with a raspberry pi 4 and FLINT the ports shut off. Not sure why but I do have multiple Quick Charge 3.0 Dual USB Power Outlets with Touch Switch. It’s cool because if I want to cut power to only the devices on the ports I can without unplugging them. Finally, the Right Angle USB C Cable makes it easy to tuck your devices away without a long plug sticking out!
You need to get MINT mobile, for $90 I have 6-months of unlimited internet. Well, technically after 5gb of hotspot/tethering, they limit your speed on the devices using the hotspot, then 35gb is the max data you can use in a month, but that doesn’t apply to me.
Visible, you can join my party and only pay $25 a month for truly unlimited data. If you use this link to signup, your first month is only $5.
