Title:
  Wifi authentication times out immediately

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to Ubuntu 15.04, wifi connections fail (not sure about the router configuration that causes connections to fail).
  Seems like regression from 14.10 (my wifi tethering from my Android used to work, but now it doesn't).
  I have a Lenovo Y50, chipset Intel 3160.

  nitz@ship:~$ modinfo iwlwifi | grep 3160
  firmware:       iwlwifi-3160-10.ucode

  Tried using versions 12 / 7 of the driver as suggested here
  (http://askubuntu.com/questions/611222/cannot-connect-to-wifi-intel-
  corporation-wireless-3160), no avail.

  From syslog when trying to connect with netowrk-manager:
