I disabled hwcrypt by putting "options ath9k nohwcrypt=1" in /etc/modprobe.d/ath9k.conf
I'm not sure about transfer speeds, I don't transfer that much data with this computer, but I do care about stability in the wifi, which did not improve. The connection drops and re-associates in different intervals, with this in dmesg: [ 7874.188947] cfg80211: All devices are disconnected, going to restore regulatory settings [ 7874.188958] cfg80211: Restoring regulatory settings [ 7874.188985] cfg80211: Calling CRDA to update world regulatory domain [ 7874.196938] cfg80211: Ignoring regulatory request Set by core since the driver uses its own custom regulatory domain [ 7874.200337] cfg80211: World regulatory domain updated: [ 7874.200341] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [ 7874.200347] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 7874.200351] cfg80211: (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 7874.200355] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) [ 7874.200359] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 7874.200363] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) [ 7875.285146] wlan0: authenticate with 58:6d:8f:4a:b6:72 [ 7875.293525] wlan0: send auth to 58:6d:8f:4a:b6:72 (try 1/3) [ 7875.295524] wlan0: authenticated [ 7875.304257] wlan0: associate with 58:6d:8f:4a:b6:72 (try 1/3) [ 7875.308054] wlan0: RX AssocResp from 58:6d:8f:4a:b6:72 (capab=0x411 status=0 aid=4) [ 7875.308065] wlan0: associated -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/971809 Title: Wifi connection unstable -- Atheros AR9485 ath9k To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/971809/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
