Eh? I haven't seen a single router that monitors packets on the channel other than their own, not to mention management frames of other AP's
A deauth packet needs the MAC address of the AP to deauth clients connected to it and the MAC address of client you want to deauth, the latter is not required and an omission would result in the packet being treated as a "broadcast deauth" but many clients do not accept broadcast deauth requests.
"Auto Channel Selection" is done very poorly on most routers, there isn't an algorithm to do so in the spec and the vast majority of routers either to a round robin on boot up or default to channel 6 when set to auto, I can count on one hand the number of routers I've seen that run any type of spectrum analysis on the available bands before selecting a channel.
The only thing I've seen that even resembles closely to what you claim is that some ISP provided routers default to "disconnect" every 12-24 hours. Some just reset the DSL connection, but some also reset the clients. This is done primarily by cheap ISP's that want to free up IP addresses they basically reset the DSL connection and complete the handshake but does receive a lease until a client on their network attempts to connect to the internet, think of it as a standby mode.
To ensure that random traffic on the network does not trigger a lease some deauth their wifi clients to reset all existing connections. However this is pretty rare as most DSL providers just reboot the router remotely....
However again random deauth MGMT frames on the same channel would not affect your own wifi network since the MAC addresses of those APs are not identical, conflicting MACs could cause issues but they could cause so many other issues as well way before anything like this could become an issue.
I really don't know why home internet connection and particularly WIFI has so many insane myths and conspiracy theories around it.
The reality is simple the 2.4ghz spectrum is the most contested unlicensed spectrum in common use with everything down from your microwave to house and car alarms, wireless headsets and other wireless radio equipment using because that spectrum has been pretty much defined as unlicensed globally way before WIFI every became a thing.
As a result WIFI equipment and especially old and or cheap equipment works really poorly, and the fact that everything from your mobile phone to your toothbrush today comes with wifi and in many cases spams the spectrum even when it's not enabled only complicates the issue.
Then you have housing that outside of the US is primarily built out of reinforced concrete or bricks even for internal walls and you get the worst possible environment for a stable connection.
It's slightly better now in Europe as wood, foam and composites are becoming more and more common for housing both internally and externally but still I've seen flats in London that the wifi won't work from one room to another if the door was closed, we later figured out that the door had an old layer of lead paint and the flat was in a converted victorian town house from the late 1800's which was built from brick and still had lead piping, some of the windows can also be made out of lead glass especially if they are old and pebbled or painted if they weren't replaced recently (which if you live in a graded building they likely weren't because it would cost a small fortune), and some of the clay bricks and fire bricks may contain high levels of tin and lead naturally.

How many IP addresses can you possibly save with this tactic? If you have 1000 subscribers, are you really going to only get 990 IP addresses, and hope that your subscribers don't all come online at the same time?
That's the problem though. Even if most people are offline during the night or during holidays/weekends, you still need to provision enough IP addresses for peak demand. ISPs aren't paying for IP addresses by the hour, they're probably leasing/buying subnets on a yearly basis, if not longer.
Your phone doesn’t sleep, its always talking to Apple or Google. IP addresses are rotated to keep trouble users at bay. Just like qos isn’t really saving on bandwidth costs.. if you download via http you’re gonna get full transfer speeds available to you, but a single BitTorrent connection won’t. It’s all about mitigating power/problem users
Maybe 10 years ago, but these days just about every Internet-connected device talks constantly.
So they would have to be not home, and not leave any IoT device on when away. Of course this happens, but is probably very rare in the evenings (and at night).
Just replying to point Ubiquiti APs can regularly scan channels for utilization and direct clients away from congested ones. I don’t think it has protection from deauth attempts but I think it would come across as congestion and send clients elsewhere..
I was looking into this last night, and just wanted to point out that Ubiquiti's 3rd generation APs do support 802.11w. The feature is labeled "Protected Management Frames" (PMF) under the WLAN Group settings on the controller.
Ubiquiti is hardly a common CPE, pro/enterprise grade WiFi equipment client management is a whole other story they balance based on anything from spectrum congestion to usage congestion on individual APs and the handover protocol between APs doesn’t use deauth unless it’s a very crude implementation.
There is roaming support in management frames and for signal strengths clients usually do their own roaming if you have 2 APs on different channels for the same SSID your client would select the best on and roam if necessary as the signal strength changes.
