I didn't think that there were any reports of issues with 3160, but now
I see that you did mention it in comment #42. At this point we've
already queued up the patch to disable beacon filtering in 3.13, so I'm
not sure that it makes sense to pull out the -8 firmware for 3160 at
this point.
Also just a note that we do plan to reintroduce the -8 firmare for 7260
once the kernel with the beacon filtering patch gets relesed.

Yep. Right now we aren't planning to bump 3.13 to use -9, but in the
future we'll have HWE kernels which will use it, so Tim went ahead and
included it when he updated linux-firmware recently.

Bug description:
Running 14.04 (beta) with Kernel 3.13.0-17-generic
I've encountered a strange and reproducible error with the
iwlwifi-7260-8.ucode firmware.
This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will
connect fine to wifi for 30 or 40 mins at a time, then will start
dropping connections repeatedly. Even modprobe -r unloading and
reloading doesn't fix the issue, only a reboot will temporarily solve
it for 40 mins at a time.
Moreover, here is what's strange, is during these episodes of
disconnection it seems to affect the actual router (2Wire), as the
other devices in the house will also start to have issues (very slow
connections, limited range,etc). Once I reboot this laptop everything
and all devices will return to normal.
This issue has been fixed by me manually removing the -8 firware from
/lib/firmware and letting the -7 firmware load instead. Since that has
been done there has not been a single issue of this happening (now
going on 4 days).
let me know if there is any other information you would like me to
provide.
