Regulatory domain incompatible with the country | Cisco C3504 | AIR-AP1815T-E-K9

Hello Community,
I'm facing issue with enable 802.11a/c on my AIR-AP1815T-E-K9 and Cisco 3504 WLC.

I have controller in Europe (is shared with public IP) in DC. In Serbia I have an access point - AIR-AP1815T-E-K9 connected directly to Internet (OEAP) and this AP doesn't broadcast 802.11a/c network.

I thought that there is a problem with Country because when I try change country I getting pop-up message with error: "Regulatory domain incompatible with the country".

In details AIR-AP1815T-E-K9 section on WLC I can see that Regulatory Domain for 802.11a/n/ac is not supported.

Could you please help me indicate a solution how to enable 802.11a/n/ac? In AP1815T-E-K9 datasheets is information that it supports 5Ghz.

WLC configured country codes: DE, FR, GB, IN, PL, RS, US
WLC Regulatory Domain:
- 802.11a/n/ac: (Indoor: -ABDEN, Outdoor: -ABDEN)
- 802.11b/g/n: (Indoor: -AE, Outdoor: -ABEN)

AP Regulatory Domains: 802.11bg:-A 802.11a:-B
AP choosen country: India -> not able to change for example on Germany or France

Please let me know if you need any additional informations/settings.

Thank you in advance.

The AP has a Regulatory Domain of "-E" but your WLC has "conflicting" Regulatory Domains from India and US.

What happens if India and US are removed?

Hi,

Here is the prcodue to change country cod eon WLC:

Step1: Disable the 802.11a and 802.11b/g networks:

(WLC) >config 802.11a disable network
(WLC) >config 802.11b disable network

Step2: Configure the country codes for the countries where our access points are installed:

(WLC) >config country DE

Step3: Enable both radios again

(WLC) >config 802.11a enable network
(WLC) >config 802.11b enable network

Let me guess, that AP that disappeared had a US Regulatory Domain?

Nope, disappears AP which has an India Redulatory Domain.

I have three AP connected to this WLC:
1st - RegDom -> Germany
2nd - RegDom -> Germany
3rd - AIR-AP1815T-E-K9 - RegDom -> India (but AP is physically in Serbia) ->

I'm not able to change regulatory domain on this last AP for example to Germany/Serbia from India.. Of course firstly I switching off both radios, then unchecking boxes with US and India and losting AP from list. Tried wait ~10 minutes to boot etc but without success.

Instresting that if I revert to US and India country on the WLC list AP is appear in ~30 seconds again.

My recommendation is to convert one of the APs to Mobility Express and then enable US. This will minimize the impact of conflicting Regulatory Domains.

1st remove AP from particular group & add mark as under default group. Once AP comes under default group then change country & test.
