Orbi AX Mesh
Firmware Version V3.2.16.6_1.4.4 I have had my Orbi RBR750 with 2 satellites for a few weeks and in general am very happy. It has covered the dead spots I used to have. However, I regurlarly ha...
what shape do the coverage cells have?
You can affect the shape by changing the position of the router/satellite - high up sends signals further, straight on tends to be stronger than side etc. Sometimes just a 90 or even 45 degree turn can make a huge difference in what picks up what.
I only know Apple stuff - The best info I know is here https://support.apple.com/en-us/HT206207
The TL/DR is
"Consider this threshold in view of the signal overlap between your wireless cells. macOS maintains a connection until the -75 dBm threshold, but 5 GHz cells are designed with a -67 dBm overlap. Those clients will remain connected to the current BSSID longer than you expect.
Also consider how the cell overlap is measured. The antennas on computers vary from model to model, and they see different cell boundaries than expected. It's always best to use the target device when you measure cell overlap.
Selection criteria for band, network, and roam candidates
macOS always defaults to the 5 GHz band over the 2.4 GHz band. This happens as long as the RSSI for a 5 GHz network is -68 dBm or better."
Other devices by other manufacturers will be different but they'll all have rules of some sort.
we have a mix of Apple, Windows and Android devices.
Both are regularly dropping signals. I am getting a new modem to replace the Suddenlink Gateway.
Those issues asside I am regularly having my Windows computers grab the 2.4 signal and not the 5.0. I have lowered the 2.4 power to 50% but I have some older devices that need it.
When I am on the 2.4 i get download speed of 7-15Mbps.
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?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. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-routerWhat channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Also try turning down the power output of the RBRs wifi radios from 100% to 50% and see if this changes anything. Under Advanced Tab/Advanced Settings/Wireless SettingsTry disabling the following and see:
Armor, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).Try setting CTS and RTS values from 64 to 2347 under Advanced Tab/Advanced Settings/Wireless Settings.

first few sets of questions are answered in earlier post.
I am a neophyte in the realm of routers, but generally know enough understand what is happening when it is explained. so, a few questions:
When the power for 2.4 is reduced from 100% to 50%(current) to 25%, what is the impact I should see?
I understand what Armor is.
What does IPv6 do?
What does 20/40Mhz Coexistence do? and what is the impact of 40Mhz only?
What is the difference between Short preamble and Long preamble modes?
