Resetting a LAP

Question

So supposing I have a LAP that I move from one WLC to another WLC on a different subnet. I reset this very same AP to factory settings using the mode button, when I attempt to join to the 2nd WLC I have issues with the AP retaining its previous IP settings, if this is the case is my only recourse to manually configure the LAP with the following commands?
AP#lwapp ap ip address <IP address> <Subnet Mask>
AP#lwapp ap ip default-gateway <IP-address>
AP#lwapp ap controller ip address <IP-address>
Shouldnt the reset from the mode button have cleared it to the point where I have a factory-default AP?

Hi Rene,
I'm not sure if this is described as a "best practice" but for us it is. There are numerous reasons that the setting of a Username/Password on an LWAPP AP becomes a valuable step in the configuration process;

Deleting the LWAPP Configuration File to Redeploy the AP
When you redeploy an access point after moving it from one location to another, you must first delete the LWAPP configuration file and restore the access point to the factory default settings. Deleting the LWAPP configuration enables the commands on the access point console to configure the static IP address on the access point, the IP address on the controller, the access point hostname, and the default gateway IP address.
To delete the LWAPP configuration and restore the factory defaults, enter the following command in EXEC mode on the access point console:
clear lwapp private-config
The clear lwapp private-config command becomes available on the access point console after the controller pushes a new username and password to the access point.

Hope this helps!
