CSCsk16432—WLC shows invalid test status in DC mode when DHCP server is disabled
The client is configured with at least one valid WLAN profile, and diagnostic channel mode testing
is initiated from the client. The client is associated to the diagnostic channel on the controller. If the
you disable the internal DHCP server on the controller and enter the command show client ccx
last-test-status on the WLC console, the WLC shows an invalid test status.

CSCsk35043—Changing security settings on controller requires disabling CB21AG
Security settings are changed on the controller. When the security settings are also changed on the
client adapter, the adapter does not reassociate to the controller unless the adapter is disabled and
then re-enabled.

CSCsk39611—Client does not roam to new access point with a power level that is greater than
minimum received signal power (MRSP)
minimum received signal power (MRSP)
A client adapter is associated to an access point that is set to –65 dBm. A neighboring access point
is enabled and set to –87 dBm. The first access point is disabled, and the client adapter roams to the
second access point. After 15 seconds, the first access point is re-enabled, but the client does not
roam to it, even though it has a stronger signal. When the power level of the second access point is
lowered to –95 dBm, the client adapter remains associated with it. When the power level for the
second access point is reduced further so that there is no signal strength, the client adapter roams to
the first access point.

second access point is reduced further so that there is no signal strength, the client adapter roams to
the first access point.
The client adapter can also be made to roam by disabling and re-enabling its radio.
Workaround: None.

CSCsk39638—Client roams to access point even though access point RSSI is lower than minimum
received signal power (MRSP)
received signal power (MRSP)
The power level of an access point is set to –65dBm, which is above the configured MRSP and the
adaptive scan threshold (AST). The client associates to the access point. A neighboring access point
is set to –85 dBm, which is below the configured MRSP and AST. The attenuation of the first access
point is increased to –88 dBm. The client roams to the second access point even though the RSSI of
this access point is below the MRSP.

CSCsk52544—After Windows in hibernate mode, ADU switches to WZC
The ADU is opened, and the CB21AG is associated to an access point. The device is then set to
hibernate mode. When the device comes out of hibernate mode, the ADU switches to WZC
approximately 10 percent of the time. This behavior is most often seen when the hibernate period is
long (overnight).

CSCsk60117—Clients experiencing disconnects when roaming
Clients experience roaming delays of between 1 and 7 seconds with various configurations.
Workaround: None.
