[Bug 1285128] [NEW] Intel Wireless 7260 wifi adapter stops showing up after update to 3.11.0-17-generic

 

Public bug reported:

This bug should affect Ubuntu installs having the above kernel (all
12.04.4 LTS or 13.10 installs will update to it) and the Intel Wireless
7260 adapter.

info on my machine:

    uname -r -v
    3.11.0-17-generic #31~precise1-Ubuntu SMP Tue Feb 4 21:25:43 UTC 2014

I have a Lenovo T440s with Ubuntu 12.04.3 installed, where I've
installed the latest kernel using:

    sudo apt-get install linux-generic-lts-saucy

As normal, I updated the kernel to 3.11.0-17-generic. After restart, I
could no longer find the wifi adapter to connect with in the top bar
network applet nor was wlan0 showing up in ifconfig. I then proceeded to
remove 3.11.0-17-generic and booted using 3.11.0-15-generic where my
wifi adapter is working well.
