I have a mixture of ap models in school environments, and it seems as if the clients are showing a preference for 39xx aps over 38xx aps. In adjacent rooms where I have different types, I will have many more connections to the 39xx ap. (there are typically 20-25 chromebooks in each classrooom) and there will be 50-60 connections to the 39xx ap and 15-20 connections to the 38xx ap in the next room. Is this possible? Preventable?
