Chris,

It seems you do not have CRDA or the wireless-regdb installed, please
install these as they are now required, otherwise a minimal world regulatory
domain is set (what you are seeing). By shifting code to userspace we have
reduced the size of ath9k, and since CRDA is no part of the regulatory support
for Linux in general distributions in general will be shipping it soon.

http://wireless.kernel.org/download/wireless-regdb/wireless-regdb-2009.01.15.tar.bz2
Once in the directory just do (no need to build):

sudo make install

http://wireless.kernel.org/download/crda/crda-1.0.1.tar.bz2

crda requires proper building:

make
sudo make install

http://wireless.kernel.org/en/developers/Regulatory

That should correct your info to match your Colombia regulatory domain:

country CO:
        (2402 - 2472 @ 40), (3, 27)
        (5170 - 5250 @ 20), (3, 17)
        (5250 - 5330 @ 20), (3, 23), DFS
        (5735 - 5835 @ 20), (3, 30)

Here is your card's reg info:

--
ath9k: Country alpha2 being used: CO
Regpair detected: 0x10
--

Here is your channel info because you lack CRDA (seems you have single 2.4 GHz band card):
