Ah yes, sorry so you use this then: country CO: (2402 - 2472 @ 40), (3, 27) (5170 - 5250 @ 20), (3, 17) (5250 - 5330 @ 20), (3, 23), DFS (5735 - 5835 @ 20), (3, 30) So you loose out on 5490 - 5710 range given that the card has been programmed for that regulatory domain. You cannot override this, this built into the EEPROM and due to regulatory restrictions this cannot be changed or left to the user to say where they are. On Linux we however do enable the user to restrict the device further, but never enable more than what the card was calibrated / designed for. > I am trying to debug this card since it works on kernel-2.6.36.2 but not > any later one. Define "works" and "not works". You can bisect if you know two kernel releases that you can use a bisection points, a good one and a bad one. Please review how to do that. Luis
