Is it possible to connect AIR-LAP1242AG-S-K9 Access Points to an existing WLC-4402-25-K9 which are populated with AIR-LAP1242AG-A-K9? The difference is in the "S" and "A" in the part numbers. The "S" APs somehow could not join the WLC. Please suggest what should be done. Thanks a lot!
So long as your WLC is running 4.1 or greater, you can have AP with multiple country codes. You just need to add all the country codes you want to be allowed to join the controller.
