I'd call that more of a workaround than a solution. It seems apparent that there is some firmware aspect to the problems, but from others with similar problems it sounds like it's at least less prevalent with 3.15 and 3.16 kernels.
I've identified a couple of fixes that could be responsible for the improved behavior, and I've made a test build for trusty with these fixes. I'd appreciate it if you could give it a try (with the -8 firmware) and let me know how it works for you. I've posted the build at: http://people.canonical.com/~sforshee/lp1349572/linux-3.13.0-32.57+lp1349572v201408111147/ Thanks! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1349108 Title: Disconnections problems each day after upgrade linux-firmware:amd64 (1.127.4, 1.127.5) Status in “linux” package in Ubuntu: Incomplete Bug description: Jul 27 13:15:28 HOSTNAME wpa_supplicant[1020]: wlan0: CTRL-EVENT-SCAN-STARTED Jul 27 13:15:38 HOSTNAME wpa_supplicant[1020]: wlan0: CTRL-EVENT-DISCONNECTED bssid=a0:b1:c2:d3:e4:f5 reason=4 locally_generated=1 Jul 27 13:15:38 HOSTNAME NetworkManager[955]: <warn> Connection disconnected (reason -4) Jul 27 13:15:38 HOSTNAME kernel: [61424.675959] cfg80211: Calling CRDA to update world regulatory domain Jul 27 13:15:38 HOSTNAME NetworkManager[955]: <info> (wlan0): supplicant interface state: completed -> disconnected Jul 27 13:15:38 HOSTNAME kernel: [61424.682734] cfg80211: World regulatory domain updated: Jul 27 13:15:38 HOSTNAME kernel: [61424.682741] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) Jul 27 13:15:38 HOSTNAME kernel: [61424.682746] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:38 HOSTNAME kernel: [61424.682750] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:38 HOSTNAME kernel: [61424.682753] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:38 HOSTNAME kernel: [61424.682756] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:38 HOSTNAME kernel: [61424.682760] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:38 HOSTNAME wpa_supplicant[1020]: wlan0: CTRL-EVENT-SCAN-STARTED Jul 27 13:15:38 HOSTNAME NetworkManager[955]: <info> (wlan0): supplicant interface state: disconnected -> scanning Jul 27 13:15:39 HOSTNAME wpa_supplicant[1020]: wlan0: SME: Trying to authenticate with a0:b1:c2:d3:e4:f5 (SSID='SSIDNAME' freq=2437 MHz) Jul 27 13:15:39 HOSTNAME kernel: [61425.528312] wlan0: authenticate with a0:b1:c2:d3:e4:f5 Jul 27 13:15:39 HOSTNAME kernel: [61425.530148] wlan0: send auth to a0:b1:c2:d3:e4:f5 (try 1/3) Jul 27 13:15:39 HOSTNAME NetworkManager[955]: <info> (wlan0): supplicant interface state: scanning -> authenticating Jul 27 13:15:39 HOSTNAME wpa_supplicant[1020]: wlan0: Trying to associate with a0:b1:c2:d3:e4:f5 (SSID='SSIDNAME' freq=2437 MHz) Jul 27 13:15:39 HOSTNAME kernel: [61425.538366] wlan0: authenticated Jul 27 13:15:39 HOSTNAME kernel: [61425.540490] wlan0: associate with a0:b1:c2:d3:e4:f5 (try 1/3) Jul 27 13:15:39 HOSTNAME NetworkManager[955]: <info> (wlan0): supplicant interface state: authenticating -> associating Jul 27 13:15:39 HOSTNAME NetworkManager[955]: <info> (wlan0): roamed from BSSID a0:b1:c2:d3:e4:f5 (SSIDNAME) to (none) ((none)) Jul 27 13:15:39 HOSTNAME kernel: [61425.568127] wlan0: RX AssocResp from a0:b1:c2:d3:e4:f5 (capab=0x431 status=0 aid=2) Jul 27 13:15:39 HOSTNAME wpa_supplicant[1020]: wlan0: Associated with a0:b1:c2:d3:e4:f5 Jul 27 13:15:39 HOSTNAME kernel: [61425.576541] wlan0: associated Jul 27 13:15:39 HOSTNAME NetworkManager[955]: <info> (wlan0): supplicant interface state: associating -> 4-way handshake Jul 27 13:15:40 HOSTNAME wpa_supplicant[1020]: wlan0: CTRL-EVENT-DISCONNECTED bssid=a0:b1:c2:d3:e4:f5 reason=4 locally_generated=1 Jul 27 13:15:40 HOSTNAME wpa_supplicant[1020]: wlan0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect Jul 27 13:15:40 HOSTNAME wpa_supplicant[1020]: wlan0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="SSIDNAME" auth_failures=1 duration=10 Jul 27 13:15:40 HOSTNAME NetworkManager[955]: <warn> Connection disconnected (reason -4) Jul 27 13:15:40 HOSTNAME kernel: [61426.610886] cfg80211: Calling CRDA to update world regulatory domain Jul 27 13:15:40 HOSTNAME kernel: [61426.616505] cfg80211: World regulatory domain updated: Jul 27 13:15:40 HOSTNAME kernel: [61426.616512] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) Jul 27 13:15:40 HOSTNAME kernel: [61426.616517] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:40 HOSTNAME kernel: [61426.616520] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:40 HOSTNAME kernel: [61426.616524] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:40 HOSTNAME kernel: [61426.616527] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:40 HOSTNAME kernel: [61426.616530] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) Jul 27 13:15:40 HOSTNAME NetworkManager[955]: <info> (wlan0): supplicant interface state: 4-way handshake -> disconnected Jul 27 13:15:40 HOSTNAME NetworkManager[955]: <info> Activation (wlan0/wireless): disconnected during association, asking for new key.
