I figure it might help other people with NETS to explain what this scan is.
There are some old YouTube videos about using spectrum expert.

If you really want to get insight into the spectrum, ebay an Cisco 3702I, and use Cisco spectrum expert ( free download and can be used on the t470) to get insight in layer 1. Start with ARM, and then manually from ch 36 and up. On a 20mhz channel you should get around 180Mbits max, likely much less. If that is ok, use the MacBook wifi to make a connection to the ap515 and do the iperf test again.all locally. Run an wired iperf test, on 1Gbps port you should get around 900+Mbits throughput. Make sure that the utp cable to the switch is ok. 20mhz channel width, Wpa2, no transition for now. Any upstair neighbours ? Put that 515 in the living room, 15dbm 5ghz, 10dbm 2.4ghz. Multipath keeps you connected, but expect frame error rate going to be significant. Mounting it on the wall causes the wave to propagate vertically, which is not good. It will propagate the radiowave in the horizontal plane, not vertical. The ap needs to mounted on the ceiling facing down, anything higher then 4 meters is a cause for concern. This will result in retries with different MCS, making the process even longer, which you can visualize with Wireshark. If the parent can't hear the child due to noise, well screaming will not help. And like your phone is a little child, it may hear the parent, but the phones voice is too low to make a punch. Sound gets distorted, so does radio, same thing just different wavelength. That people can hear you, does not mean people understand what you are saying. Anything more just causes trouble in your environment. Start with the 515, turn power down to 15dbm. Line of sight is vital or suffer the consequences. I don't agree with some advice given here. Based on your insiderr picture it can only jump to heavily utilized channels. Hence you get disconnected if the client can't follow. Anytime a radar wave is registered, the ap must cease using that channel and will jump to something else. What is the channel utilisation here ? Then you have one ap on channel 52, which is a DFS channel. The 5ghz, you got one ap on ch 40 which is probably not usable because your neighbours use 80mhz channel width and can blast anything through it, maybe a Chromecast, camera, who knows. The 2.4 GHz is usable for low speed or iot/nest. ARM can help you a bit, but your neighbours are killing the spectrum. Your first post shows an enormous amount of aps as interfering and a few as valid. Nest Thermostat (which is in the same hallway as the AP345, in direct line of sight) Symptoms are consistent across many kinds of devices: I can't think of why on earth I can't get a solid, stable wifi connection with these things.

TLDR: Despite updating to latest firmware, manually setting to wide-open channels for all radios and tweaking power to hit a recommended SNR, both phones and computers can't seem to hold a connection, and are extremely slow when they do have one. Particularly huge shoutout to /u/Educational-Meal386 for patiently walking me through some concepts and some recommended targets for signal strength. First off, huge thanks for your first round of suggestions.
