Trouble installing intel 7260 - iwlwifi on clearfog board ( 4.4 kernel )

[Valk]

Ok I'm stuck and need some help.

 

Trying to install an intel 7260 wifi + bt mini pcie card in my clearfog (as an access point but that's the next step). I'm using https://github.com/igorpecovnik/lib/ to build and using the dev branch (tried all 3). Installs everything ok Ethernet, 3G modem but the intel 7260 is killing me.

 

Tried installing the ucode from version 13 - 17 from:

 

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi?s%5b%5d=iwlmvm#firmware

http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/?id=c883a6b6186bb2415761d287cbac773062911212

https://github.com/OpenELEC/iwlwifi-firmware/tree/master/firmware

 

Using the Gentoo wiki for a guide on how to setup the kernel: https://wiki.gentoo.org/wiki/Iwlwifi

 

Using the 3.x kernel I managed to get it to load but the 4.x keep giving me errors:

That's just one of the errors I've received as I've been building all different kernels trying to solve the problem.

root@armada:~# lspci -k

Any help would be greatly appreciated (or even a recommendation on an alternate mini pci-e wifi card to use as an access point).

DEV branch (as the name indicates) is most problematic and is to avoid. NEXT branch is better but fibre support is not operational. Wireless should work fine here but in both 4.x cases, those are not matured kernels and things can go wrong.
