I just converted one IOS AP to LWAPP. While the conversion was smooth, I can not use the 802.11a radio. Here is the output for :
show ap config 802.11a AP
AP Regulatory Domain............................. -N
Well I know that is supposed to e newZealand, but how comes that the same AP is set for Americas on its B radio?
(Cisco Controller) >show ap config 802.11b AP
AP Regulatory Domain............................. -A
802.11b/g works fine.
Any ideas how to fix that problem?
Thanks

Hi Michael,
Just guessing that the A radio is a modular version that was installed as an add-on (don't forget the Regulatory domain info is hard coded on the radio). So I think you have two choices;
1. Order and install the corect A radio module with the correct regulatory domain.
2. Try the following;
Note Controllers running software release 4.0 or earlier do not have the ability to control access points in more than one regulatory domain.
Configuring Country Codes
Controllers and access points are designed for use in many countries with varying regulatory requirements. The radios within the access points are assigned to a specific regulatory domain at the factory (such as -E for Europe), but the country code enables you to specify a particular country of operation (such as FR for France or ES for Spain). Configuring a country code ensures that each radio's broadcast frequency bands, interfaces, channels, and transmit power levels are compliant with country-specific regulations.
Generally, you configure one country code per controller, the one matching the physical location of the controller and its access points. However, controller software release 4.1 allows you to configure up to 20 country codes per controller. This multiple-country support enables you to manage access points in various countries from a single controller.
Guidelines for Configuring Multiple Country Codes
Follow these guidelines when configuring multiple country codes:
The multiple-country feature is not supported for use with Cisco Aironet mesh access points. If a mesh access point is already connected to the controller, multiple-country configuration is rejected. If multiple-country support is configured, mesh access points are not permitted to join the controller.
When the multiple-country feature is being used, all controllers intended to join the same RF group must be configured with the same set of countries, configured in the same order.
When multiple countries are configured and the radio resource management (RRM) auto-RF feature is enabled, the auto-RF feature is limited to only the channels that are legal in all configured countries and to the lowest power level common to all configured countries. The access points are always able to use all legal frequencies, but non-common channels can only be assigned manually.
--------------------------------------------------------------------------------
Note If an access point was already set to a higher legal power level or is configured manually, the power level is limited only by the particular country to which that access point is assigned.
--------------------------------------------------------------------------------
When multiple countries are configured, the 802.11a network is disabled for all countries if any country does not support the 802.11a radio or there are no common channels on the 802.11a radio.
You can configure country codes through the controller GUI or CLI.
Here's how;
Hope this helps!

Hi Rob,
Thanks for your answer. Unfortunately it is an 1240 with FIXED radios:)
I'll try the link and let you know if it helped!

Hi Michael,
Can you please confirm which model of AP you are having and then I will update you how to resolve this problem?

Hello Ankur,
Sory I forgot to mention, it is an AP1240 with fixed radios!

As a rule A means FCC and N means North America also known as Canada. Country regulatory domain is configured in the controller under the wireless regulatory domain setting.
