Hello I am trying to set up wireless support on an embedded X86 based device (PCengines WRAP) using an atheros based CM-9 card manufactured by Wistron Neweb. I am using cfg80211 with the internal regulatory domain database. I am observing the following with dmesg [ 133.324451] cfg80211: Calling CRDA to update world regulatory domain [ 133.344421] cfg80211: World regulatory domain updated: [ 133.346021] (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 133.347622] (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 133.348902] (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 133.349842] (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 133.350455] (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 133.351736] (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 133.353431] cfg80211: Calling CRDA for country: CH [ 133.443881] cfg80211: Regulatory domain changed to country: CH [ 133.444568] (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 133.445486] (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 133.446397] (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 133.447630] (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 133.448863] (5490000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 2700 mBm) [ 141.971982] ath5k 0000:00:0d.0: registered as 'phy0' [ 142.453824] ath: EEPROM regdomain: 0x0 [ 142.453881] ath: EEPROM indicates default country code should be used [ 142.453940] ath: doing EEPROM country->regdmn map search [ 142.454009] ath: country maps to regdmn code: 0x3a [ 142.454062] ath: Country alpha2 being used: US [ 142.454109] ath: Regpair used: 0x3a [ 146.738786] phy0: Selected rate control algorithm 'minstrel' [ 146.838666] ath5k phy0: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43) [ 146.839284] ath5k phy0: RF5112B multiband radio found (0x36) [ 146.842202] cfg80211: Calling CRDA for country: US [ 146.936338] cfg80211: Current regulatory domain intersected: [ 146.937470] (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 146.938415] (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 146.939290] (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 1700 mBm) [ 146.940525] (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 146.941758] (5490000 KHz - 5600000 KHz @ 40000 KHz), (N/A, 2000 mBm) [ 146.942702] (5650000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 2000 mBm) Although I specify a country code CH at module loading, it appears that the athk5 driver is calling cfg80211 with a default country code. Why is US the default country code and why is it called at all. Thanks Erich Titl
