Hi Jim,
I work with Cambium networks regularly and can help get the offline APs back up and running.
I handle remote management for several campground deployments, so I understand the unique challenges you face with outdoor mesh networks in varied terrain.
Would be happy to take a look at your cnMaestro setup and help optimize coverage across your 12 points.
Mesh should really be “last resort” and not a design “element”.
Any chance you could back haul the APs on 60GHZ? You will get much better performance out of the APs if they aren’t trying to use their airtime to server clients and repeat traffic.
