I just installed Ubuntu 16.04 on a laptop with Intel Wireless 7260, but the kernel does not recognize wifi. The laptop does not have ethernet, and wifi is my only way to connect to the internet.

As I searched, many people have this problem.

One issue that I see is that the intel driver for kernel 4.3+ should be iwlwifi-7260-17.ucode, but Ubuntu uses iwlwifi-7260-13.ucode.

In /lib/firmware, iwlwifi-7260-16.ucode is available. I downloaded iwlwifi-7260-16.ucode and iwlwifi-7260-17.ucode from Intel website, but still no success.

After one day of struggling, I found it has nothing to do with driver.

If anyone has this problem, the solution is

echo "blacklist acer-wmi"  >>  /etc/modprobe.d/blacklist.conf

I don't know what is this problem, but I believe it should be permanently fixed.
