[Solved] Intel 7260 wifi no driver

Hello there. I am completely new to Arch.
I'm on kernel 3.18.2 and gnome as my desktop.
I've updated linux-firmware, tried manually installing iwlwifi (moved *.ucode to /lib/firmware-doubt I did this correctly), reinstalled iw, wpa_supplicant, dialog, pacman -Syu,  and a number of other things over the last week.

lspci:

Re: [Solved] Intel 7260 wifi no driver

This driver is iwlwifi.  Grep the output of dmesg for iwlwifi and see what you come up with. 

Also, you should be able to modprobe iwlwifi manually, but you should probably first reinstall linux-firmware to ensure that all the proper files are in place.

Thanks for the help WonderWoofy!

I did a pacman -Syu and pacman -S linux-firmware
While arch-chroot dmesg:

[   14.150360] iwlwifi 0000:06:00.0: enabling device (0000 -> 0002)
[   14.150535] iwlwifi 0000:06:00.0: irq 36 for MSI/MSI-X

[   38.411901] iwlwifi 0000:06:00.0: L1 Enabled - LTR Enabled
[   49.607555] iwlwifi 0000:06:00.0: L1 Enabled - LTR Enabled
[   49.607817] iwlwifi 0000:06:00.0: L1 Enabled - LTR Enabled

While logged in normally, dmesg had nothing for iwlwifi
How exactly can I do that with modprobe?

Re: [Solved] Intel 7260 wifi no driver

modprobe is just the command used to manually load a module (or the one that will automatically handle dependencies as well).  So you would just do something like:

# modprobe iwlwifi 

But you might want to check the output of lsmod to see if the module is in fact already loaded.

Re: [Solved] Intel 7260 wifi no driver

lsmod only shows a temperature module
I did some googling around but I cannot find how to make or download the iwlwifi module.
Any help with that?
