====== Allow channels 12,13,14 ======

At this current time the only way to allow channels 12,13,14 is to make your own custom firmware

Very simple - once you get all the stuff installed

Do a "make menuconfig"

Goto Kernel Modules -> Wireless Drivers

Highlight kmod-ath and hit enter, Configuration and enter

Choose this setting:

[*] Force Atheros drivers to respect the user's regdomain settings

I don't see an option to enable this for Broadcom, but I only am
compiling for my Atheros devices

The above is for OpenWRT images.

For building your own Gargoyle images, follow the Documentation
section for Developers - clone the git, setup build environment,
then do -- make custom -- and you can follow the above to
goto Kernel Modules -> Wireless Drivers, etc.

Even easier - you can edit the config.in files under the target
directories and set this option: CONFIG_ATH_USER_REGD=y
