Its simply stupid to have the user be involved, period, the fact that a user would be involved should only be for testing or helping compliance for a busted device, development, research and obviously hacking. Linux allows all these but by default a device with firmware and a custom regdomain that will barf if you try to use a channel that is not allowed is a restriction in firmware. Feel free to reverse engineer that if you don't like it but it just won't be supported or go upstream. Now, the common denominator is generally optimized for best performance as well so you shouldn't have to do anything, and for APs -- this is typically carefully crafted for a region, also highly optimized. >>>> It doesn't seem like you are getting your original requests getting >>>> processed, so I don't think CRDA is passing it.

Its unclear what results you got, and yeah if the device is restricted then its just the fw telling the driver its channels and you can't use them. That's it. You won't be able to override information then unless you hack the firmware.
