As I explained previously, the cards are tuned and configured for a particular regulatory domain when they're manufactured. The driver cannot assume that the card will be capable of complying with another regulatory domain.
That's false. Atheros does not produce distinct chips for different countries or markets. <http://marc.info/?l=linux-wireless&m=125072768530674> There is only ONE chip, with custom "regdomain" values in the EEPROM. And the *driver* applies constraints based on that value. No more no less. Then, crda/wireless-regdb only can narrows things a bit more. Atheros chips can go beyond IEEE 802.11 frecuencies. dd-wrt is selling "DD-WRT Superchannel Extension": http://www.dd-wrt.com/shop/catalog/product_info.php?cPath=22&products_id=717 [...] SuperChannel allows you to use special frequencies from 2.3 Ghz - 2.7 Ghz (802.11g capable devices only) and 4.9 Ghz - 6.1 Ghz (802.11a capable devices only). [...] Please note that the DD-WRT Superchannel license can only be applied to certain routers equipped with Atheros based WLAN-hardware. http://www.qsl.net/kb9mwr/projects/wireless/ddwrt-ham.jpg Mikrotik also sells a 'code' to unlock "custom" frequencies: http://www.mikrotik.com/documentation//manual_2.7/Interface/Wireless.html#ht2761782821 Ubiquiti used to do it: http://www.qsl.net/kb9mwr/projects/wireless/airos-ham.jpg You can read further info in: http://www.qsl.net/kb9mwr/projects/wireless/modify.html -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
