[Bug 1311257] Re: Wifi cannot connect or unstable after suspend 14.04

 

I have a iwlwifi-3160 card, kernel 4.2.6 on Debian Jessie. I am using iwlwifi-3160-15.ucode.
Unfortunately, killing wpa_supplicant does not work.

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.  When I had 13.10, my wifi worked without a
  problem, but once I erased it and installed 14.04, wifi will not
  connect after suspend.  Ethernet works fine.  The only way I've found
  to resolve this is to restart my computer.  I have a Lenovo T420.  If
  I try to connect after suspend, it shows the Wifi Networks, tries to
  connect, and  says "Disconnected..." every time.
