AIR-CAP3602I-E-K9

AIR-LAP1142N-E-K9    

AIR-CAP3502I-E-K9   All a/n & b/g/n is up and working fine


But I have outdoor AP

Can anyone please advise what could be the issue

So I guess your fix was to choose a single Country Code (SA) that allows the M Mesh AP along with your E AP's to join?

For country code of "GB" your APs should have the regulatory domain of "E".  Your 1550, however, isn't.  And this is why the MESH APs radio is down.

Dear Leo,


Thanks for your reply


I have noticed that -M  domain for the country Kuwait,Saudi and Qatar.


If I reconfigure the country code as one of this country will it solve my issue?


In that case what about my other APs with -E regulatory domain?  will it associate with AP with other code ?


Regards

Deva

May not work. 


The re-configure, for example UK, Kuwait, KSA and Qatar in your WLC then only the COMMON CHANNELS/Radio will be enabled.


Any conflicting regulations pertaining to channels and radios will be disabled.

Asper your query, I think your AP have have wrong regulatery domain AIR-CAP1552E-M-K9.


It should be in europe....like : AIR-CAP1552E-E-K9.



You have to buy right AP with correct regulatery domain.

Sandeep,

U can set 2 country code on WLC; GB and SA/KU/QA, It should work.


I never tried this but atleast u can try to set and let me know.


But is is normally recommanded to buy country regulated specific AP.


Befor changing the country code , u must disable 802.11a and 802.11b.

Choose Wireless > Country

After changing country code, dont forget to enable 802.11 and 802.11b networks.

No, MESH AP are not allowed to join multiple country code WLC.  You should work with whomever provided you that 1552 to get the correct one for GB



HTH,

I would definitely agree with stepen however if that doesn't work you can try flashing a ios image with the correct reg domain. I belive the restrictions are all in hardware and not software.

Correct me if I'm wrong.

Steve is right about the WLC can only have one country code set. If multiple are set, these MESH AP's will not join. Like everyone mentioned, you need to return the MESH AP for a new one for GB. You will not be able to change the MESH AP's country code.

Hi Deva,


Normal APs can work with multiple country code but this is the problem with MESH AP:

You need to have another WLC to support Mesh AP.


Running multiple country codes in a single WLC is a bad idea(Not recommanded). Only common channels will be allowed.  Power will also be curtailed to the most common one. The best thing is to get another WLC and group them by using the same regulatory domain

The ONLY SOLUTION is to talk to the vendor who sold you the AP with the wrong regulatory domain and politely ask them if they can replace them for you. 


Another solution is to get another WLC.

There is nothing you can do here. You need to get another MESH AP.

Just be cautious about doing that as you might be breaking the regulation for the country the AP's are located. As long as you check to make sure that channels are allowed and that TX power isn't higher than what it's suppose to be, then your okay.

As a vendor, we usually would return the AP for the correct country code due to regulations and consistency.

Well thanks for your input!

Hi Deva,

I am also agree with Scott

Normally:


When multiple countries are configured and the radio resource management (RRM) auto-RF feature is enabled, the common channels allowed is derived by performing a union (or superset) of the allowed channels in the countries. The access points are always able to use all legal frequencies, but noncommon channels can only be assigned manually.

The access point can only operate on the channels for the countries that they are designed for.


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.


Mesh AP: They do support multiple country code, but with regulations, the WLC will use the common channels and power for each of the countries you have defined. Now this will never change so its still best to have separate WLC per country if possible. Especially with mesh since the backhaul is on the 5ghz, this is really your limitation is you have AP's in a country where there is no allowed 5ghz or a minimum number of allowed channels.
