Bad environment detected on Radio[0]:Channel[11] by AP Garage - WAC740
I am getting this error. Not sure why. Sometimes it goes down, sometimes it does not. Is it RF? Temperature? It is outside (well, in a garage, safe from elements... but not controlled), and curr...
It is clear for your Neighbour AP list that Channel 1, 6 and 11 are congested & the behaviour is expected in this kind of condition.
Below is the details shows that how many ap's are configured to a particular channel:
Channel-1 has configured with 17 AP's, 6 has configured with 10 AP's and channel-11 has configured with 13 AP's and all these are non overlapping channels so you left out with overlapping channels
You can select any channel from these 2,3,4,5,7,8,9,10, and make sure you use different channel for each AP.
Below is the link which explains the WAC740 PoE requirement,

Yessir, I am very much aware of the specs. This is my 2nd switch that clearly meets the specs. All 4 access points have problems powering. Even when it is the only device attached to the switch! The switch reports it is providing instantaneous 8.9W. Its well below the 30W capability of the switch, and 30W fully . Here is an excerpt from the manual of the HPE Aruba 3810M
• IEEE 802.3at Power over Ethernet (PoE+) provides up to 30 W per port that allows support of the latest PoE+ capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af compliant end device; eliminates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments
