Intel Corporation Wireless 7260 on Mageia 5 (but with kernel-tmb-laptop)
Raw
intel_7260.md

After updating from Mageia 4 to 5, the builtin wireless on my Lenovo T440s stopped working. When attempting to configure the card via the network center or drakconnect, I would get the message "Unable to find network interface for selected device (using iwlwifi driver)". Removing and re-adding the iwlwifi module via modprobe did nothing. The wireless card was definitely available according to lspci. I had the iwlwifi-agn-ucode package installed. ls /lib/firmare listed several ucode files for iwlwifi-7260.

Some investigation found Mageia 5 does not provide a kernel-tmb-laptop package, which means I was still running on 3.14.43-tmb-laptop-1.mga4. Changing the kernel just to go from 3.14 to 3.19 but perhaps lose laptop features didn't seem worth it.

To get the wireless working again, I just needed to go to https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi download the correct ucode file (iwlwifi-7260-ucode-25.228.9.0.tgz) which contains iwlwifi-7260-9.ucode. Copy to /lib/firmare, restart, and everything is back to normal!
