Appendix D Error and Event Messages
802.11 Subsystem Messages
Error Message DOT11-4-CANT_ASSOC: Interface [interface], cannot associate
[characters]
Explanation The indicated interface device could not associate to an indicated parent access point.
Recommended Action Check the configuration of the parent access point and this unit to make sure
there is a match.
Error Message DOT11-2-PROCESS_INITIALIZATION_FAILED: The background process for the
radio could not be started: [characters]
Explanation The initialization process used by the indicated interface failed for some reason,
possibly a transient error.
Recommended Action Perform a reload of the access point. If this fails to rectify the problem, perform
a power cycle. If this still fails, try downgrading the access point firmware to the previous version.
Error Message DOT11-2-RADIO_HW_RESET: Radio subsystem is undergoing hardware reset
to recover from problem
Explanation An unrecoverable error occurred that could not be resolved by a soft reset.
Recommended Action None.
Error Message DOT11-4-MAXRETRIES: Packet to client [chars] [mac] reached max retries
[int], remove the client
Explanation A packet sent to the client has not been successfully delivered many times, and the max
retries limit has been reached. The client is deleted from the association table.
Recommended Action Force re authentication from the client to reassociate to the router.
Error Message DOT11-4-RM_INCAPABLE: Interface [interface]
Explanation Indicated interface does not support the radio management feature.
Recommended Action None.
Error Message DOT11-4-RM_INCORRECT_INTERFACE: Invalid interface, either not existing
or non-radio
Explanation A radio management request discovered that the interface either does not exist or is not
a radio interface.
