Wifi not working (Intel) on HP Spectre x360 13

Your exact device 8086:24fd, subsystem 1010 is not yet covered in the driver version in Ubuntu 14.04. I suggest that you install a later 4.8.14 linux-image as well as the required firmware.

I assume that your installation is 64-bit; confirm:

arch

If the terminal returns x86_64 then yours is a 64-bit install. Download the files to your desktop:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.14/linux-headers-4.8.14-040814-generic_4.8.14-040814.201612101431_amd64.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.14/linux-image-4.8.14-040814-generic_4.8.14-040814.201612101431_amd64.deb

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.14/linux-headers-4.8.14-040814_4.8.14-040814.201612101431_all.deb <--The package I initially missed.

http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.2_all.deb

Install them all from the terminal:

cd ~/Desktop
sudo dpkg -i *.deb

Reboot and tell us if your wireless is working.
