(Resending because it failed to deliver to linux-wireless) Hi, This is the set up on my laptop: - AR9565 wireless network adapter - Acer Aspire V5-122P laptop - AMD A6-1450M - Linux kernel built from sources v4.1.0-rc8 In config I changed CONFIG_ATH9K to be built as module. Here's the snippet from config file in /boot/ directory: CONFIG_ATH5K_PCI=y CONFIG_ATH9K_HW=m CONFIG_ATH9K_COMMON=m CONFIG_ATH9K_BTCOEX_SUPPORT=y CONFIG_ATH9K=m CONFIG_ATH9K_PCI=y CONFIG_ATH9K_AHB=y CONFIG_ATH9K_DEBUGFS=y Next, I built the kernel and installed it. WiFi worked fine. Then I removed ath9k module by running modprobe -r ath9k and WiFi went. Then I added the module back by running modprobe -v ath9k which seemed to go through fine: ~$ sudo modprobe -v ath9k insmod /lib/modules/4.1.0-rc8-task11-dirty/kernel/net/wireless/cfg80211.ko insmod /lib/modules/4.1.0-rc8-task11-dirty/kernel/net/mac80211/mac80211.ko insmod /lib/modules/4.1.0-rc8-task11-dirty/kernel/drivers/net/wireless/ath/ath.ko insmod /lib/modules/4.1.0-rc8-task11-dirty/kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko insmod /lib/modules/4.1.0-rc8-task11-dirty/kernel/drivers/net/wireless/ath/ath9k/ath9k_common.ko insmod /lib/modules/4.1.0-rc8-task11-dirty/kernel/drivers/net/wireless/ath/ath9k/ath9k.ko However the WiFi failed to connect. Kernel log shows wlan0 deauthenticating by local choice. Here is relevant dmesg output which includes removal of ath9k: [ 2381.070339] wlan0: deauthenticating from <AP-MAC-ADDRESS> by local choice (Reason: 3=DEAUTH_LEAVING) [ 2381.112740] cfg80211: Calling CRDA to update world regulatory domain [ 2381.128568] cfg80211: World regulatory domain updated: [ 2381.128583] cfg80211: DFS Master region: unset [ 2381.128589] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 2381.128599] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2381.128607] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2381.128614] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2381.128621] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2381.128628] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2381.167390] ath9k: ath9k: Driver unloaded [ 2437.514472] cfg80211: Calling CRDA to update world regulatory domain [ 2437.532271] cfg80211: World regulatory domain updated: [ 2437.532295] cfg80211: DFS Master region: unset [ 2437.532301] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) [ 2437.532310] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2437.532317] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2437.532324] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2437.532331] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2437.532337] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) [ 2438.557451] ath: phy0: WB335 1-ANT card detected [ 2438.564368] ath: phy0: Enable LNA combining [ 2438.565503] ath: phy0: ASPM enabled: 0x43 [ 2438.565511] ath: EEPROM regdomain: 0x65 [ 2438.565515] ath: EEPROM indicates we should expect a direct regpair map [ 2438.565522] ath: Country alpha2 being used: 00 [ 2438.565526] ath: Regpair used: 0x65 [ 2438.567745] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht' [ 2438.569010] ieee80211 phy0: Atheros AR9565 Rev:1 mem=0xffffc90000800000, irq=34 [ 2438.587718] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 2458.673488] wlan0: authenticate with <AP-MAC-ADDRESS> [ 2458.688912] wlan0: send auth to <AP-MAC-ADDRESS> (try 1/3) [ 2458.690924] wlan0: authenticated [ 2463.694617] wlan0: aborting authentication with <AP-MAC-ADDRESS> by local choice (Reason: 3=DEAUTH_LEAVING) [ 2463.702156] wlan0: authenticate with <AP-MAC-ADDRESS> [ 2463.714400] wlan0: send auth to <AP-MAC-ADDRESS> (try 1/3) [ 2463.716451] wlan0: authenticated [ 2468.715271] wlan0: aborting authentication with <AP-MAC-ADDRESS> by local choice (Reason: 3=DEAUTH_LEAVING) ...and it retries few more times Rebooting the machine resolves the issue. If you need further details, let me know. I've got the set up on my machine.
