this adapter supported since kernel 4.6.

the kernel version in ubuntu 16.04 4.4.

you can install kernel 4.8 ubuntu 16.04 way:

sudo add-apt-repository ppa:canonical-kernel-team/ppa  sudo apt update sudo apt install linux-generic-lts-yakkety sudo add-apt-repository -r ppa:canonical-kernel-team/ppa

reboot after it.

after linux-generic-lts-yakkety package appears in main ubuntu repositories (it should happen soon) start getting updates.

you need install firmware can done by

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161_all.deb sudo dpkg -i linux-firmware_1.161_all.deb
