Interference
Detection
Look at the fault description to
determine which AP reported the
interference, then take corrective
action by removing the interference
source.
Ad-hoc network creation
detected: ssid
An ad-hoc network was formed
by some wireless clients (where
ssid is the Service Set Identifier
of the UnmanagedRadio’s BSS).
One of your infrastructure APs or
other clients sent this information
to the WLSE via your WDS
setup.
IDS > Manage
Network-Wide IDS
Settings > Ad-hoc
Network Detection
If the information is available, the
WLSE will show the clients that are
participating in the network (and that
it can detect) in the fault details page.
Use the Location Manager to find
these APs and verify that this is not a
security issue.
