Orbi firmware v2.1.1.16 discussion

v2.1.1.16 woes,
Long story - but the auto update upgraded my RBR50/RBS50 around Xmas. Since then I have a very unreliable network. Router/Sat reboots randomly.
Lots of people scremaing in my house. Ive had my ORBI since June... and was very reliable.

I basically went back to the older firmware 2.0.0.74 and updated NVRAM via telnet for the 3 auto update params. But my router still had random reboots.
I then went back to v2.1.1.16 and updated NVRAM params to auto update. I also noticed with v2.1.1.16 that my Sat/RBS50 accepts connections in the beginning after a reboot but when I look an hour later it (Sat/RBS50) has no connections - they all pile up on the router RBR50.

I even tried to hardware the Sat/RBS50 since I had a Gb switch nearby.   Same thing - the Sat will accept a bunch of connections in the beginning after a boot (10 or 15 connections) but hours later they are gone... piled up on the RBR50.

This morning the router rebooted and it went back to factory defaults... all my customizations were gone. I was going to load the backup file but also wondered if it would be better to start fresh and just update the essential settings that I use.

My router customs are:
- Custom SID name
- Guest Network
- 10.0.0.1 LAN addresses and for DHCP
- uncheck Enable 20/40 MHz Coexistence for wireless 2.4GHz.
- I have some reserved IP addresses but didn't define them yet.

Whats unique about my network:
- About 40-45 devices on network
- 100mbps down/10up - Spectrum broadband
- 1 to 2TB data usage per month.
- 2 teenage kids that are Xbox One heavy users.
- 1 spare Xbox One is a game server.
- It's a streaming world nowadays.
- Critical for my job as I remote access/VPN into work allot.  In IT for 30 years.

Unsure what support is available as it appears that I only have 90 days of real support from June when it was purchased.... after that you have to pay. Very disappointed in this new firmware.  Wondering if I need to look for a different brand of router.  It "ORBI" was very reliable for first 7 months.
