Wrong Country code

The IOS installed in the Access Points are regionally, so that all country codes will not work. Too see which channels the controller will try and force the Access Points to use: 

(Cisco Controller) ><input>show country channels</input>


Configured Country............................. DK  - Denmark
      KEY: * = Channel is legal in this country and may be configured manually.
           A = Channel is the Auto-RF default in this country.
           . = Channel is not legal in this country.
           C = Channel has been configured for use by Auto-RF.
           x = Channel is available to be configured for use by Auto-RF.
         (-) = Regulatory Domains allowed by this country.
------------:+-+-+-+-+-+-+-+-+-+-+-+-+-+-
802.11BG    :

            : 1 2 3 4 5 6 7 8 9 0 1 2 3 4
------------:+-+-+-+-+-+-+-+-+-+-+-+-+-+-

 DK (-E)    : . A . A . A . A A A A A A A A A A A A A A A A . . . . .
------------:+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-

In the example above the Country Code is DK (-E). -E means ETSI (European Telecommunications Standards Institute) means that the Access Point must support this country setup. That can be seen by the IOS version for example AIR-LAP1232AG-E-K9 the -E means ETSI and it will support European Country codes. Not US (United States)
