Some success, at least for my HS110s ! We’ll see if it is permanent. This morning I decided to turn off all the auto mesh checking functions for all the APs at my home “site”. Lo and behold, all of the former HS110 zombies are now pingable, and better yet, show up in the Sense app. I don’t know enough about Ubiquiti and mesh checking to figure out the root cause. And it may be that reseting the AP parameters did enough of a reset to restore ARP cache data for a while, but not permanently. But it’s either a clue or a fix.
For Ubiquiti users and @DevOpsTodd , here’s what I turned off at the Site level using the classic web UI. Not sure what you would do if you needed the mesh, but all my APs are wired.
