Title:
  Intel 3160 wireless card no longer able to connect to wifi networks

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Laptop: Lenovo Y70 Touch
  Wireless Card: Intel Corporation Wireless 3160 (rev 93)

  When running Ubuntu Gnome 14.10 (on a live USB drive) I am able to
  connect to wifi networks without any issue. When running Ubuntu Gnome
  15.04 (either on live USB or installed and fully updated) I am able to
  see the list of available wifi networks, but not able to connect.
  Selecting one and entering the password makes the network manager
  applet indicate that it is "Connecting..." but then it gives up after
  about a minute or so and reverts back to "Not Connected". I have
  tested this without network encryption as well, and the same result
  occurs.

  I have ran a wifi debugging script, here is the output:

  For Ubuntu 14.10 - http://pastebin.com/aLUhTyrM
  For Ubuntu 15.04 - http://pastebin.com/f0yRjQUC

  Again, the card seems to work perfectly on 14.10, but is unable to connect to any networks on 15.04. I haven't completely narrowed this down to the firmware, however that is the most prominent difference (aside from the kernel itself) that I notice in the above files (14.10 uses iwlwifi-3160-9.ucode, while 15.04 uses iwlwifi-3160-10.ucode).
