The secondary controller AP’s wireless profiles do not appear in my wireless 
network.

In case you have both primary and secondary controller APs in the network, the 
secondary controller AP’s WLAN radio is turned off as long as the primary 
controller AP is turned on. Thus, you will not see any of the secondary controller 
AP’s wireless profiles in your wireless network.

The controller AP cannot detect some of the APs in the network.

Only NWAs in managed AP mode are visible to the controller AP.

The configuration updates I applied to the controller AP are not taking effect.

• If you have both primary and secondary controller APs in the network, note that 

you can only configure one at a time. While the primary controller AP is online, 

the secondary controller AP cannot configure any of the managed APs. However, 

it still has to be turned on to synchronize with the primary controller AP’s latest 

settings.

• Be sure you update the primary controller AP and not the secondary controller 

AP when setting the congfiguration for the managed APs. If you accidentally set 

up the secondary controller AP instead, the changes you made will not take 

effect. They are overridden by the configurations of the primary controller AP

• The managed APs may be turned off or out of range while you were updating 

their profiles. The changes will take effect when the managed APs are turned on 

or are within range again.

Can the controller AP update managed APs that are turned off.

A managed AP may potentially be turned off if it is within range of its controller AP 
while the controller AP updates its settings. The managed AP retains the last 
settings acquired from the controller AP and is automatically updated once it is 
detected again by the controller AP.
