Intel Wireless 7260 not working after kernel update [Solved]

Hi Guys,

After I updated the kernel from 4.1.15-r1 to 4.4.6, my Intel 7260 Wireless card stopped working correctly, as now it takes 1 or 2 minutes until it is found by the system.
I know that this is a firmware problem but I can't seem to find the correct firmware for this new kernel version. I'm currently using iwlwifi-7260-13.ucode for the firmware but it don't work very well in this version.
Did anyone had a similar problem or know how to solve it?

Thank you.

run dmesg | grep -i firmware and see if it gives any hints
http://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/tree/ has from .7 up to .17 ucode

I use emerge linux-firmware to acquire firmware. Sometimes it does not contain all current firmware requiring manual download to /lib/firmware. Run ls /lib/firmware/*iwlwifi-7260*. If you do not have all the versions listed at http://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/tree/ in your /lib/firmware you should download them to /lib/firmware and reboot. This leaves the kernel free to pick the correct firmware for your particular 7260. once the kernel chooses you can read the choice in dmesg and delete the unchosen from /lib/firmware.
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi suggests that kernel 4.3+ wants /lib/firmware/iwlwifi-7260-16.ucode to be present. Which can also be downloaded from https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7260-ucode-16.242414.0.tgz which extracts to iwlwifi-7260-16.ucode and LICENSE.iwlwifi-7260-ucode and a readme. Depending on how you handle licenses you should(may need) to add the license to /lib/firmware.
