não pode ativar o wifi do Alienware R2 no Ubuntu 16.04 LTS

Question

Acabei de instalar o 16.04 LTS no meu laptop Alienware 15 R2 e posso conectar-me à Internet via cabo Ethernet, mas a conexão wifi está ausente. Eu tentei as soluções postadas em aqui e aqui e aqui mas nenhum funcionou. Aqui estão alguns comandos e saídas que eu acho que as pessoas precisam como detalhes.

lspci -nnk | grep -iA2 net; dmesg | grep iwl

A saída

tem duas partes:

3b:00.0 Ethernet controller [0200]: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller [1969:e0a1] (rev 10)
