The regulatory domain on most cards actually ship with a world regulatory domain, if they ship with a different country regulatory domain that is up to the manufacturer not Atheros, but most likely they are actually not incorrect. When you do have more channels than you are supposed you can restrict this further with 'iw reg set' but enabling new channels is not something that is that easy from a regulatory perspective which is why this is not something that is done. A manufacturer typically tests only the channels enabled on their regulatory domain and programs the EEPROM with CTL information for those settings, not for other regulatory domains. Modifying the EEPROM is something up to manufacturers to do under current testing scenarios and due to current legislation, this is not supported nor it is intended to be. If world roaming we provide world roaming enhancements to help with the default passive scan an no beaconing on some channels. This currently consists of lifting passive scan flags and no-beaconing flags from channels you see APs on. This should increase the time it takes to scan for your AP after the first time or for other APs on that channel. It also means you can start hostapd or adhoc on these channels.
