Have you ever experienced an issue where you were unable to enable to the 5 GHz radio on an AP in the T regulatory domain? I'm working on an issue where a LAP-2602I-T lightweight access point will not let me set the Country Code to BR or enable the a/n radio.
You shouldn't have problems with that because 2602i AP uses -T regulatory domain for Country Code Brazil. Do you have multiple country codes enabled? If you do check at the Advanced Tab of the AP Configuration if the AP is using the right country config.
We vfd that the WLC and the AP itself had the proper country codes enabled. What we ended up doing was replacing the 2602 with a spare 1142, and now we see clients connecting on both bands. I'm suspecting an issue with that particular 2602, but we won't know for sure until we replace 'like for like'.
