You need to upgrade the kernel.

Connect to internet by wire or some other way and run in terminal:

sudo apt-get install linux-generic-lts-wily
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.156_all.deb
sudo dpkg -i linux-firmware_1.156_all.deb
sudo cp /lib/firmware/iwlwifi-7265D-13.ucode  /lib/firmware/iwlwifi-3165-13.ucode

and reboot.
