[Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
Hello everyone. I had a similar issue on elementary OS freya when coming out of suspend with Intel Wireless-N 7260. I could patch it with "nmcli nm sleep false" , however, it seems like uninstalling laptop-mode-tools fixed it definitively. Also, this fixed another issue: after I issues a suspend command, it took 10-20 seconds until the laptop actually turned off. Now it turns off instantly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311257 Title: Wifi cannot connect or unstable after suspend 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-nettool/+bug/1311257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

A while back, my wifi connection kept dropping. I had to keep re- booting Ubuntu 14.04 to try and get my wifi connection back. I have a Lenovo Thinkpad X220T laptop with Intel Centrino Advanced-N 6205 wifi card. I'm using a WPA2 connection. I tried disabling the N mode of the wifi card, as detailed in this link: http://askubuntu.com/questions/457729/ubuntu-14-04-wireless-constantly- disconnects I also tried killing wpa_supplicant as detailed here in this bug report. Eventually, I upgraded my Linux kernel from 3.13 to 3.16 (the v3.16 kernel is available on Ubuntu 14.04.2) and that mostly fixed my wifi issues. I've upgraded to the 3.19 kernel this week and my wifi seems to be working on this kernel as well.

I am running Xubuntu 14.04 and since the upgrade I am also experiencing wifi disconnected after resume. It's an Intel 7260 chip. A few comments that might help: - I did add iwlwifi to SUSPEND_MODULES which made no difference - nmcli nm responds with "Object 'nm' is unknown"... is that because I am running xfce rather than Unity? - sudo killall wpa_supplicant seems to force a search and reconnect, which is successful... - so, I added the latter to a sleep.d script, but then found that (again since the 14.04 upgrade) none of those scripts are being executed on resume!

In reference to Milton's comments (and thanks for the follow-ups) - my problems (listed in #11) are *not* related to a post-suspend loss of wifi. My problems happen consistently on a fresh boot.

The unnecesary modprobe lines were product of a line that I had added to /etc/pm/config.d/modules SUSPEND_MODULES="$SUSPEND_MODULES iwldvm iwlwifi" Now, I commented that line (# ) and I added in my /etc/modprobe.d/iwlwifi.conf: options iwlwifi 11n_disable=1 Lastly, the script in /etc/pm/sleep.d/ (in my case it's named: /etc/pm/sleep.d/nm-prob ) now looks like this: #!/bin/sh case "${1}" in resume|thaw) nmcli nm sleep false #modprobe -rv iwldvm iwlwifi #modprobe -v iwlwifi #modprobe -v iwldvm killall wpa_supplicant dhclient -r wlan0 dhclient wlan0 nmcli nm sleep false #restart network-manager ;; esac After TWO days I can confirm that these changes solved both the problem after suspend as the unstable connection problem.

[Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
I'll mirror the above reports, I'm using a Intel Corporation Centrino Advanced-N 6205 on Linux Mint 17 (Ubuntu 14.04 Trusty), I recently upgraded from 12.04 Linux Mint 16 (Ubuntu 13.04 Saucy) using a complete clean reinstall and now the problem manifests. On Mint 16 (13.04) I had *no* wifi problems in my office (I've been here for 6 months). Since reinstalling 11 days ago with Mint 17 (14.04) in the office (with a BTHub) I'm kicked off of wifi every 5-15 minutes, at home (on a Virgin Wifi device) I have no connection problems. I believe the problem is a combination of 14.04 and the BTHubs here in the office (we have two, different SSIDs, I could use them both before, now both exhibit the same kick-me-off behaviour). Currently I solve the problem using "sudo pkill wpa_supplicant" as discovered in this thread. This takes me back online, it feels very much like the same behaviour shown in this thread with 14.04 and for #1294044. Before discovering this bug report I was using the widget in the notification bar to disable and then enable the wireless device. Re. "it tooks me ages to find this page" as others have noted - I've been hunting around with log messages for 11 days before I found this bug report, nothing else I found got me even close to a useful diagnosis. $ uname -a Linux ian-Latitude-E6420 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux $ lspci ... 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34) I have the latest firmware for the 6205 (verifying against Intel's site: http://www.intel.com/support/wireless/wlan/sb/CS-034398.htm) $ sudo lshw -C network *-network description: Ethernet interface product: 82579LM Gigabit Network Connection vendor: Intel Corporation physical id: 19 bus info: pci@:00:19.0 logical name: eth0 version: 04 serial: 5c:26:0a:61:e2:24 capacity: 1Gbit/s width: 32 bits clock: 33MHz capabilities: pm msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000e driverversion=2.3.2-k firmware=0.13-3 latency=0 link=no multicast=yes port=twisted pair resources: irq:43 memory:e670-e671 memory:e678-e6780fff ioport:5040(size=32) *-network description: Wireless interface product: Centrino Advanced-N 6205 [Taylor Peak] vendor: Intel Corporation physical id: 0 bus info: pci@:03:00.0 logical name: wlan0 version: 34 serial: a0:88:b4:65:ed:7c width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=3.13.0-24-generic firmware=18.168.6.1 ip=192.168.1.65 latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn resources: irq:45 memory:e660-e6601fff A typical dmesg (from when the problem first starts to the wifi being offline): [22291.312726] wlan0: deauthenticated from 00:81:d8:64:33:4a (Reason: 6) [22291.35] cfg80211: Calling CRDA to update world regulatory domain [22291.351954] cfg80211: World regulatory domain updated: [22291.351963] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) [22291.351998] cfg80211: (2402000 KHz - 2472000 KHz @ 4 KHz), (300 mBi, 2000 mBm) [22291.352004] cfg80211: (2457000 KHz - 2482000 KHz @ 4 KHz), (300 mBi, 2000 mBm) [22291.352009] cfg80211: (2474000 KHz - 2494000 KHz @ 2 KHz), (300 mBi, 2000 mBm) [22291.352013] cfg80211: (517 KHz - 525 KHz @ 4 KHz), (300 mBi, 2000 mBm) [22291.352017] cfg80211: (5735000 KHz - 5835000 KHz @ 4 KHz), (300 mBi, 2000 mBm) [22306.450438] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready The same for syslog: Nov 18 15:35:17 ian-Latitude-E6420 NetworkManager[1067]: Activation (wlan0/wireless): association took too long, failing activation.

Same issue here on a X301 - The only way to revive the card is to "nmcli nm sleep false" as suggested above. - rmmod/insmod of iwl modules does not help - rfkill always reports power on; toggeling rfkill off/on does not solve the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311257 Title: Wifi cannot connect or unstable after suspend 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-nettool/+bug/1311257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hm... http://ubuntuforums.org/showthread.php?t=2182058&p=12824696#post12824696 That indicates a different solution might work - replace "killall wpa_supplicant" above with "nmcli nm sleep false". I haven't tried it but it might work.

I have the same issue. Upgraded 12.04 to 14.04 on a Lenovo T530. Killing wpa_supplicant resolves the issue, so I wrote the following script which seems to work: Put it in /etc/pm/sleep.d/wpa_supplicant_workaround : #!/bin/sh case "$1" in resume|thaw) killall wpa_supplicant ;; esac Not really ideal, but it saves a bit of typing at each resume. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311257 Title: Wifi cannot connect or unstable after suspend 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-nettool/+bug/1311257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
