no se puede habilitar wifi de Alienware R2 en Ubuntu 16.04 LTS

Acabo de instalar 16.04 LTS en mi computadora portátil Alienware 15 R2 y puedo conectarme a Internet mediante un cable Ethernet, pero falta la conexión wifi. Probé las soluciones publicadas enaquíyaquíyaquípero ninguno funcionó. Aquí hay algunos comandos y salidas que encontré que la gente necesita como detalles.

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

La salida tiene dos partes:
