The device appears, but refuses to connect to any AP, timing out in less than a second. (3.3-ARCH did not have this bug.) dmesg output while trying to connect to an open AP follows. > # modprobe ath9k > [ 213.662569] ath: EEPROM regdomain: 0x60 > [ 213.662574] ath: EEPROM indicates we should expect a direct regpair map > [ 213.662580] ath: Country alpha2 being used: 00 > [ 213.662583] ath: Regpair used: 0x60 > [ 213.664533] ieee80211 phy1: Selected rate control algorithm 'ath9k_rate_control' > [ 213.666228] Registered led device: ath9k-phy1 > [ 213.666255] ieee80211 phy1: Atheros AR9285 Rev:2 mem=0xffffc90022d60000, irq=17 > # ip link set wlan0 up > [ 215.577316] ADDRCONF(NETDEV_UP): wlan0: link is not ready > # iw wlan0 connect -w cloud > [ 217.667382] wlan0: authenticate with 00:23:8e:e1:6c:c8 (try 1) > [ 217.864456] wlan0: authenticate with 00:23:8e:e1:6c:c8 (try 2) > [ 218.063975] wlan0: authenticate with 00:23:8e:e1:6c:c8 (try 3) > [ 218.263514] wlan0: authentication with 00:23:8e:e1:6c:c8 timed out > # iw wlan0 connect -w cloud > [ 276.603232] wlan0: authenticate with 00:23:8e:e1:6c:c8 (try 1) > [ 276.802003] wlan0: authenticate with 00:23:8e:e1:6c:c8 (try 2) > [ 277.001461] wlan0: authenticate with 00:23:8e:e1:6c:c8 (try 3) > [ 277.200945] wlan0: authentication with 00:23:8e:e1:6c:c8 timed out Using "debug=0xe01" with rmmod/modprobe causes no visible difference.
