Several Bugs found in installing a Orbi 970 system
I just installed an Orbi 970 system, router and 2 satellites. I am on FW version 9.12.3.3. They went in place where a comparable Orbi 960 router and 2 satellites were. I set everything up by takin...

You don't have 2 different DHCp servers, the ISP Gateway and 971, do you? Bad idea if you do. You should change it to one or the other.
Static is different than reserved. I made static IP addresses because those units were making a lot of DHCP requests for IP, long before their lease expires. "DHCP flooding". Probably still happens, but the devices that did, I gave them static addresses. If they got reserved addresses, that just tells the DHCP server what IP address to give to them and no one else - it would not stop DHCP flooding. With static addresses the dhCP server doesn't even know the device exists. FYI I have my 2 satellites on reserved addresses, so I always know how to get to their status and debug pages.
BTW you can easily shrink your DHCP window from say, .2 to .254, over to .2 to .150, and make a lot of addresses available that you can statically assign if you want. Nothing bad happens, and if a DHCP device client has a IP address outside the new range, the next time its lease expires, it will get an IP in the new range. Nothing will break by doing this.
I know all about 6 vs 5 GHz, for the little speed I am giving up (I get up to 900 Mbps on WiFi 5 vs. 1100 on WiFi 6 on those 2 devices), I don't have the devices popping into 5G cellular as I move around the house - which is totally annoying lol.
Look up Dynamic Frequency Selection if you want to learn more about the DSP channels. It's a little more automated than you surmised!

FURRYe38 we may have lost one of my noted differences between the 960 and 970 in my first post - the fact you cannot select a default 6GHz channel now. Any news on that?

BE series will not have a separate 6Ghz network. 960 series was a one off to help ensure 6Ghz devices would connect back then. It's all automatic now. Not sure if NG will gives us 6Ghz channel selection.

Maybe they reason the range is so short on 6GHz compared to 5GHz and 2.4GHz there's little chance of congestion from competing networks.
I wonder if it ever changes off of 69...

Something you can test, turn on your 960 series. Set it to a different SSID name. Change the channel to same as what the 970 is using. I'd set power to med or low on the 960. Put the 960 is same room or near the 970, 10 feet or more. Check the 970 to see what it's using. Might need a reboot of the 970 to see if it changes the channel to something different to avoid using same channel as the 960.

Yeah maybe, for the disruption not that interested lol.
Plus, it might not be that easy - I have been reading about how channels are managed with WiFi 6E.
With my dumbed-down understanding, it appears (I could be wrong), that In Wi-Fi 6E, a process called fast passive scanning is being used to focus on a reduced set of channels called preferred scanning channels (PSC). This is because on the 6E bandwidth, there would be so much to scan with larger bandwidth etc., it might take multi-seconds to find a channel.
PSCs are a set of 15 20-MHz channels that are spaced every 80 MHz. So the Orbi router will set its primary channel, in this case 69, so that it can be easily discovered by a device, and devices will use passive scanning to find it a lot quicker.
That said, I am thinking it might take something significant to cause the Orbi to switch off 69 - especially in today's world where there are very few devices, if any, in a house that uses 6E and is pumping a lot of data so that congestion results. Also, with the short range of 6E, maybe congestion really plays a small part in switching the channel?

Well possible.
Maybe putting on the RBS as well from the 960 could force the 970 to change...If interference levels get too high...
