Thanks FURRYe38, answers below:

 

What Firmware version is currently loaded?


-> the latest: V4.6.3.16_2.0.51

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
-> Arris TM1602 (but that did not change)
 
Is the RBS connected directly the the back of the RBR or is there any LAN swtich in between? 
-> There is Netgear GS105 in between, but that also did not change and was working fine for months
 
What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.

-> Using Auto. I will try your recommendations

 

Any Wifi Neighbors near by? If so, how many?
-> About 5
 
Try disabling the following and see:
Armor.
-> was always disabled
 
Set 20/40Mhz Coexistence to 40Mhz only. Set CTS to 2347. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s). Under Advanced Tab/Advanced Settings/Wireless Settings
-> I only see a "Enable 20/40 MHz Coexistence " but I cannot specify 40. Will try your other recommendations< Remove the check mark from the box then select apply. This sets 40Mhz only.

Has a power off for 1 minute then back ON with the ISP modem, Switch and Orbi system been performed since last update?

I presume that you have checked if forgetting the wireless connection on your mobile device and re-connecting it helps.

The new firmware update you are using may have included an update to the wireless drivers and the device parameters could need refreshing.

I will methodically go through the suggested changes.

Yesterday I did this: Set 20/40Mhz Coexistence to 40Mhz only. Set CTS to 2347. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s). Under Advanced Tab/Advanced Settings/Wireless Settings

It seemed to work better this morning, but by mit day it started dropping iOS devices again.

I use 2 iPads. Once one gets dropped, I sometimes can simply reconnect, but often the first bit of network activity then makes it drop again. Then I did let it sit for 5 minutes and the reconnect and then wait another 5 minutes until I start using it for network stuff. That worked better, but next thing my iPhone get kicked out of the WiFi.

It really feels like the Orbis are just overwhelmed with juggling the  iOS devices.

Will try the 'forget network' on all iOS next. After that I'll try the channel settings you recommended.

Thanks again!
