Title:
  Intel Wifi 3160 connects to AP but no internet access with 802.11n
  2.4Ghz

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have a Lenovo Y50-70 with Intel Wifi 3160

  I can associate and authenticate with my wifi router but I have been
  unable to send/receive data using 802.11n 2.4Ghz on Ubuntu 14.04.2.
  Trying to ping the router IP address just times out.

  I guessed this might be fixed in the latest version of Ubuntu so I
  installed the daily build of 15.10 from http://cdimage.ubuntu.com
  /daily-live/current/ dated June 3rd but got the same results.

  I can access the internet using the 5Ghz band but the range is not as
  good as 2.4Ghz so I get very low speeds at the top of my house.

  All my other laptops & phones can connect at 2.4Ghz at 70-150Mbit with
  no problems at the top of my house. I've tested with iPhones, Nexus 5,
  Moto X, Lenovo Thinkpads and Macbooks.

  I've also tested Ubuntu 14.04.2 with Kernel 4.1 and iwlwifi firmware
  version 13 with the same results and I've tested this using the 15.04
  live cd with the same results.

  I've tried rfkill block bluetooth to turn off bluetooth.

  I have attached a file with all the necessary debug info from Ubuntu
  15.10 daily fresh installation.

  The only output from dmesg after trying 2.4Ghz is as follows:
