This article is current to the last version of airControl, but will not be updated further since airControl has been retired.
This article describes a possible cause and solution for scenarios where discovered devices are placed in the Unplaced Devices folder for no apparent reason.
Problem, Cause and Solution
Problem: When running discovery task with 'Resolve topology' option checked, discovered devices fall into 'Unplaced Devices' folder. Network topology may also not resolve properly.
Possible Cause: Failed SSH logins will always place devices in the Unplaced Devices folder since no information was obtained to determine device's actual position in the topology.
Recommended Solution: Verify that the SSH settings are correct and that port 22 is open.
