I have a number of sites managed by an L3 Omada Controller. Following an upgrade elsewhere a seemingly random portion of the switches and EAPs somehow lost their connection to the controller, though others are fine. SSH was enabled, and I'm able to ssh into all of them, including the ones disconnected, so there is nothing wrong with the network itself. After that though I hit a dead end, I can't execute anything since it won't give root privs, and anyway I can't see any promising commands either from help or /bin|/sbin|/usr/bin|/usr/sbin etc. I was able to reset a switch via Web GUI and then it readopted (though it lost all settings), but I can't pull up anything on the EAPs even though I can SSH into them.

Short of driving a few hundred miles and then wandering about a mile with a ladder to hit physical reset buttons, is there any sort of recovery capability in Omada devices when you do have remote access to all of them but a handful have lost their controller connection somehow? Thanks so much for any suggestions or pointers if I've missed something obvious.
