Comment 15 for bug 1311257

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
