Hi Corey,

As you can see from the previous messages, Fix Released just means that
the bug has been fixed in the latest upstream kernel (v4.6) that I
tested.

After testing the kernel v4.6 I also verified that the Intel Wireless
7260 support is not an issue anymore, starting from the kernel v4.4 (I
had 4.3).

  Wireless keeps disconnecting no matter what Intel 7260 driver I use.
  Since this problem didn't occur in ubuntu 14.04, I guess it is kernel related.
