5Ghz is going to be enabled under  Wireless > 802.11a/n > Network.  There is a checkbox there to enable/disable the network

Steve,

This checkbox was marked and even so the clients don't find the frequency 5 ghz.

It's necessary enable this frequency in the LAP?

This checkbox was marked and even so the clients don't find the frequency 5 ghz.

Hmmmmm ... what country is the AP and the client located.  Maybe it's part of the Regulatory Domain.  In some countries, 802.11a is not allowed so the WLC will not be able to enable 802.11a/n.

Next, what is the exact model of the wireless client.  Maybe the wireless client (like early iPhone and iPad) is only 802.11b/g.

Leo Laohoo,

The Regulatory Domain is:

Configured Country Code (s): US

Regulatory Domain: 802.11a:     -A

                                 802.11bg:   -A

I'm in Brazil, and when I try change Country Code, don't allow apply the configuration, and return to Country Code US.

Alexandre.

Ok, just as I suspected.

802.11a/n is most likely disabled because you have two different regulatory domain.  Your WLC is configured for the US (-A) but your APs are in Brazil (-T, -Z, -N).

If you enable Brazil and disable US, do you see both radios go up?

I'm trying change country code by GUI, but he don't apply.

Post the output to the WLC command "sh sysinfo".

You are only allowing one country code... US:

Configured Country............................... US  - United States

You would need to add the other country code.  The others have posted how to do that piece.

Thanks,

No you didn't.  It is still set to the US.

Try again.

If the AP is located in the US then you can enable the US country code. If the AP is located or going to be used in Brazil, then you might be getting into trouble. AP's are made for a specific country. See this list

Using an access point for another carry can be breaking the law. Here is the USA, FCC regulates what channel and power leveled we can use.

The reason the 5ghz is not working is because the WLC has to have the country code enabled for the country code for the access point. Also, the most common channels and power levels are used. So if a country code that is configured in the WLC doesn't allow 5ghz, then all AP's even ones that are for other countries, the 5ghz will be disabled.
