Public bug reported:

Hi, I ran into a bug that made wifi unstable on my Lenovo Ideapad Y710.
I needed to disable/reenable networking about every 5 minutes.  I was
able to get some connectivity, but obviously, this is a pain in the ass.

After working with the awesome support folks at Intel, I think we
isolated the problem and solution.

The problem likely affects all laptops with the Intel(R) Wireless 7260
chipset.

The solution is to use updated firmware from here:
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-
firmware.git/plain/iwlwifi-7260-7.ucode?id=824994715e0276e64cdbf2badbe02921a78fb287

Just replace the /lib/firmware/iwlwifi-7260-7.ucode binary with the new
one.

Below is the last email I got from Luca at ilw at linux.intel.com - if
you have questions, they know the technical details to the solution.
Thanks again!

Hi Mike,

My colleague noticed that you are using an older version of the firmware
which contains a bug that may be the cause of the problem you're seeing.

We have pushed a new firmware (with a fix for this) to the
linux-firmware.git repository.  You can get it here:

http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-
firmware.git/plain/iwlwifi-7260-7.ucode?id=824994715e0276e64cdbf2badbe02921a78fb287

Just replace the /lib/firmware/iwlwifi-7260-7.ucode binary with the new
one.

I checked Ubuntu's packages and it seems that they only updated to the
new one in the linux-firmware 1.122 package (for trusty).  Ubuntu Saucy
(13.10) still has the old version in the linux-firmware 1.116 package.
It would be nice if someone would poke Ubuntu to add 1.122 to the
saucy-updates or something.  I believe Linux Mint is following Ubuntu in
this case.

I hope this helps!

(And thanks to Emmanuel for the help ;)
