in actual trunk, when i compile for ar71xx (TP-Link1043ND) with kernel-modules -> -> wireless drivers -> kmod-ath -> configuration -> YES "Force Atheros drivers to respect the user's regdomain settings"
in /etc/config/wireless i set: option 'channel' '12' option 'country' 'JP' option 'txpower' '20' but it fails. after checking: iw reg get it show JP, but with: iw phy phy0 info | fgrep MHz * 2412 MHz [1] (17.0 dBm) * 2417 MHz [2] (18.0 dBm) * 2422 MHz [3] (18.0 dBm) * 2427 MHz [4] (18.0 dBm) * 2432 MHz [5] (18.0 dBm) * 2437 MHz [6] (18.0 dBm) * 2442 MHz [7] (18.0 dBm) * 2447 MHz [8] (18.0 dBm) * 2452 MHz [9] (18.0 dBm) * 2457 MHz [10] (18.0 dBm) * 2462 MHz [11] (17.0 dBm) * 2467 MHz [12] (19.0 dBm) * 2472 MHz [13] (19.0 dBm) * 2484 MHz [14] (19.0 dBm) we can see a, that it is not the same like CRDA: cfg80211: Calling CRDA for country: JP cfg80211: Regulatory domain changed to country: JP cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm) cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (N/A, 2000 mBm) cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (N/A, 2000 mBm) cfg80211: (4910000 KHz - 4930000 KHz @ 10000 KHz), (N/A, 2300 mBm) cfg80211: (4910000 KHz - 4990000 KHz @ 40000 KHz), (N/A, 2300 mBm) cfg80211: (4930000 KHz - 4950000 KHz @ 10000 KHz), (N/A, 2300 mBm) cfg80211: (5030000 KHz - 5045000 KHz @ 10000 KHz), (N/A, 2300 mBm) cfg80211: (5030000 KHz - 5090000 KHz @ 40000 KHz), (N/A, 2300 mBm) cfg80211: (5050000 KHz - 5060000 KHz @ 10000 KHz), (N/A, 2300 mBm) cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm) cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 2000 mBm) cfg80211: (5490000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 2300 mBm) so this fails: root@box:~ iw dev wlan0 set txpower fixed 2000 command failed: Invalid argument (-22) the txpower is fine, when not using the ath-kmodule-option. then we can use txpower 27 with country US. what to do now? bye, Bastian. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
