Thank you, @matzipan. I also had this problem since upgrading to kernel 4.4 on linux mint 17.3 (ubuntu 14.04.03 derivative). Removing `laptop-mode-tools` fixed it instantly for me, as well.

[Desktop-packages] [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 Desktop Packages, which is subscribed to gnome-nettool in Ubuntu. https://bugs.launchpad.net/bugs/1311257 Title: Wifi cannot connect or unstable after suspend 14.04 Status in gnome-nettool package in Ubuntu: Confirmed Bug description: I've tried every solution, such as 1. editing /etc/pm/config.d to add SUSPEND_MODULES="iwlwifi" 2. editing /etc/modprobe/d/wilwifi.conf to add: options iwlwifi bt_coex_active=0 options iwlwifi 11n_disable=1 3. running: sudo rmmod iwlwifi && sudo modprobe iwlwifi 4. stopping, starting, or restarting Network Manager Nothing seems to work.

[Desktop-packages] [Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
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.

[Desktop-packages] [Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
I had the same problem.
And I tries several fixes.
Something helped me (it seems)...
Symptoms:
# ifup wlan0
interface wlan0 not configured
# lshw -C network
[...]
*-network DISABLED
description: Wireless interface
Probably this resoled the issue:
# gksu gedit /etc/pm/config.d/unload_modules
SUSPEND_MODULES=$SUSPEND_MODULES iwlwifi
{by http://www.webupd8.org/2013/01/fix-wireless-or-wired-network-

[Desktop-packages] [Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
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!

[Desktop-packages] [Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
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. Frankly my E6420 can be 'wobbly' after suspend (it has been since 10.10) so I rarely suspend (it can fail to restart wifi, sometimes it refuses to wake at all, sometimes it works fine but won't shutdown - I've no idea what causes this instability). For the time being I'm using a 2nd wifi device (a EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]) whilst in the office to avoid the loss of wifi problem. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-nettool in Ubuntu. https://bugs.launchpad.net/bugs/1311257 Title: Wifi cannot connect or unstable after suspend 14.04 Status in “gnome-nettool” package in Ubuntu: Confirmed Bug description: I've tried every solution, such as 1. editing /etc/pm/config.d to add SUSPEND_MODULES=iwlwifi 2. editing /etc/modprobe/d/wilwifi.conf to add: options iwlwifi bt_coex_active=0 options iwlwifi 11n_disable=1 3. running: sudo rmmod iwlwifi sudo modprobe iwlwifi 4. stopping, starting, or restarting Network Manager Nothing seems to work.

[Desktop-packages] [Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04
Ok, a follow up:
An important thing is that my Wireless adapter is: Network controller: Intel
Corporation Wireless 7260 (rev 83)
So, my first comment (#13) comment had a problem, as I had tried so many
things that I one solution step on the other. 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.
Hope it helps

This was the only workaround that helped me. I don't know if some of
these lines are unnecessary, but only using all of them it works.

[Desktop-packages] [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]: warn Activation (wlan0/wireless): association took too long, failing activation.

If I try to connect after suspend, it shows the Wifi Networks, tries to connect, and says Disconnected... every time. ~$ sudo apt-get update; sudo apt-get install hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | egrep -i 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nnk | grep -iA2 net; lsusb; nmcli nm status; sudo lshw -short; uname -a; dmesg | egrep '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|rt2|rt3|rt5|rt6|rt7|usb|witch|wl';sudo dmidecode|egrep 'anufact|roduct|erial|elease'; iwconfig; cat /etc/modprobe.d/* | egrep '80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl'; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|egrep 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; ls -lia /boot; sudo lsmod Ign http://dl.google.com stable InRelease Hit http://dl.google.com stable Release.gpg Hit http://dl.google.com stable Release Hit http://repository.spotify.com stable InRelease Ign http://us.archive.ubuntu.com trusty InRelease Hit http://dl.google.com stable/main amd64 Packages Hit http://dl.google.com stable/main i386 Packages Ign http://extras.ubuntu.com trusty InRelease Hit http://repository.spotify.com stable/non-free amd64 Packages Ign http://security.ubuntu.com trusty-security InRelease Ign http://us.archive.ubuntu.com trusty-updates InRelease Hit http://repository.spotify.com stable/non-free i386 Packages Hit http://extras.ubuntu.com trusty Release.gpg Hit http://security.ubuntu.com trusty-security Release.gpg Ign http://us.archive.ubuntu.com trusty-backports InRelease Hit http://extras.ubuntu.com trusty Release Ign http://us.archive.ubuntu.com trusty-proposed InRelease Hit http://security.ubuntu.com trusty-security Release Hit http://extras.ubuntu.com trusty/main Sources Ign http://dl.google.com stable/main Translation-en_US Hit http://us.archive.ubuntu.com trusty Release.gpg Ign http://dl.google.com stable/main Translation-en Hit http://security.ubuntu.com trusty-security/main Sources Hit http://extras.ubuntu.com trusty/main amd64 Packages Hit http://us.archive.ubuntu.com trusty-updates Release.gpg Hit http://security.ubuntu.com trusty-security/restricted Sources Hit http://extras.ubuntu.com trusty/main i386 Packages Hit http://us.archive.ubuntu.com trusty-backports Release.gpg Hit http://security.ubuntu.com trusty-security/universe Sources Hit http://us.archive.ubuntu.com trusty-proposed Release.gpg Hit http://security.ubuntu.com trusty-security/multiverse Sources Hit http://us.archive.ubuntu.com trusty Release Ign http://ppa.launchpad.net trusty InRelease Hit http://security.ubuntu.com trusty-security/main amd64 Packages Hit http://us.archive.ubuntu.com trusty-updates Release Ign http://ppa.launchpad.net trusty InRelease Hit http://security.ubuntu.com trusty-security/restricted amd64 Packages Ign http://repository.spotify.com stable/non-free Translation-en_US Hit http://us.archive.ubuntu.com trusty-backports Release Ign http://ppa.launchpad.net trusty InRelease Ign http://repository.spotify.com stable/non-free Translation-en Hit http://security.ubuntu.com trusty-security/universe amd64 Packages Hit http://us.archive.ubuntu.com trusty-proposed Release Ign http://ppa.launchpad.net trusty InRelease Hit http://security.ubuntu.com trusty-security/multiverse amd64 Packages Hit http://us.archive.ubuntu.com trusty/main Sources Ign http://ppa.launchpad.net trusty InRelease Hit http://security.ubuntu.com trusty-security/main i386 Packages Hit http://us.archive.ubuntu.com trusty/restricted Sources Hit http://ppa.launchpad.net trusty Release.gpg Hit http://security.ubuntu.com
