Appendix C Error and Event Messages
DOT11-2-PROCESS_INITIALIZATION_FAILED:
“The background process for the radio
could not be started: %s)
The initialization process used by the indicated interface
failed for some reason, possibly a transient error. 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.
DOT11-2-RADIO_HW_RESET: “Radio subsystem
is undergoing hardware reset to recover
from problem.”
An unrecoverable error occurred that could not be
resolved by a soft reset. None.
DOT11-2-RESET_RADIO: “Interface %s, Radio
%s, Trying hardware reset on radio.”
Used a software reset to start a radio that has failed.
Trying a hardware reset that resets all radios on the unit. None.
DOT11-4-MAXRETRIES: “Packet to client %e
reached max retries, removing the
client.”
The maximum packet send retry limit has been reached
and the client is being removed. This error message
indicates that the access point attempts to poll the client a
certain number of times, but does not receive a response.
Therefore, the client is removed from the association
table. This issue is commonly seen when the client and
access point are attempting to communicate in a noisy RF
environment. To resolve this issue, see if a snapshot reveals
noise in the radio spectrum by trying to run a
carrier busy test on the access point. Attempt
to alleviate any unwanted noise.
For more information, see the
Performing a
Carrier Busy Test on page 277 .
If there are several access points in the same
area, they could be overlapping the channel
signal or with any other wireless device in
the surrounding area. Change the channels
under Network Interfaces and select Radio-
802.11. There are three non-overlapping
channels: 1, 6, and 11.
DOT11-4-RM_INCAPABLE: “Interface %s Indicated interface does not support the radio
management feature. None.
DOT11-4-RM_INCORRECT_INTERFACE: “Invalid
interface, either not existing or non-
radio.”
A radio management request discovered that the
interface either does not exist or is not a radio interface. None.
DOT11-3-POWERS_INVALID: “Interface %s, no
valid power levels available.”
The radio driver found no valid power level settings. Investigate and correct the power source and
settings.
DOT11-4-RADIO_INVALID_FREQ: “Operating
frequency (%d) invalid - performing a
channel scan.”
The indicated frequency is invalid for operation. A channel
scan is being performed to select a valid frequency. None.
DOT11-4-RADIO_NO_FREQ: “Interface &s, all
frequencies have been blocked, interface
not started.”
The frequencies set for operation are invalid and a channel
scan is being forced to select a valid operating frequency. None.
DOT11-4-BCN_BURST_NO_MBSSID: “Beacon
burst mode is enabled but MBSSID is not
enabled, %s is down.”
Beacon burst mode can only be enabled when MBSSID is
enabled on the indicated interface. Enable the MBSSID or disable beacon
bursting on the indicated interface.
DOT11-4-BCN_BURST_TOO_MANY_DTIMS:
“Beacon burst mode is enabled and there
are too many different DTIM periods
defined. %s is down.
Beacon burst mode can only support up to four unique
DTIM values, each with a maximum of four BSSes. Change the number of unique DTIMs on the
SSIDs configured for the interface to a more
reasonable set of values.
DOT11-2-RADIO_INITIALIZATION_ERROR: “The
radio subsystem could not be initialized
(%s).”
A critical error was detected while attempting to initialize
the radio subsystem. Reload the system.
DOT11-4-UPLINK_NO_ID_PWD: “Interface %s,
no username/password supplied for uplink
authentication.”
The user failed to enter a username and/or password. Enter the username and/or password and try
again.
DOT11-5-NO_IE_CFG: ”No IEs configured for
%s (ssid index %u).”
When attempting to apply a beacon or probe response to
the radio, the beacon or probe was undefined on the
indicated SSID index. Check the IE configuration.
DOT11-4-FLASHING_RADIO: “Interface %s,
flashing radio firmware (%s).”
The indicated interface radio has been stopped to load the
indicated new firmware. None.
DOT11-4-LOADING_RADIO: “Interface %s,
loading the radio firmware (%s).”
The indicated interface radio has been stopped to load
new indicated firmware. None.
