hi, I have the same issue however none of the above fixed it for me:

- kernel 4.1rc2 doesnt fix it
- booting with bluetooth of doesnt fix it either

it just says connecting and the goes back to disconnected state, exactly
as stated above.

I also have a Y50 with an Intel 3160. I also updated the firmware but
nothing seems to help...

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

Status in System76:
  In Progress
Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Vivid:
  Fix Committed

Bug description:
  [Impact]

  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.

  [Test Case]

  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.

  [Fix]

  commit afcee962b09842d0f4191beb4a2d08251b4c7705 upstream

  [Workaround]

  Boot with bluetooth turned off. If the computer boots with the
  bluetooth turned on, the wifi will not work, even if you first turn
  off the bluetooth. A restart is needed.
