ne peut pas activer le wifi d'Alienware R2 sur Ubuntu 16.04 LTS

Je viens d'installer 16.04 LTS sur mon ordinateur portable Alienware 15 R2 et je peux me connecter à Internet via un câble Ethernet, mais la connexion wifi est manquante. J'ai essayé les solutions postées sur ici et ici et ici mais aucune n'a fonctionné. Voici quelques commandes et sorties dont j'ai trouvé que les gens ont besoin comme détails.

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

la sortie comporte deux parties:

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


Subsystem: Device [0707:2400] 


Kernel driver in use: alx


3c:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32)


Subsystem: Bigfoot Networks, Inc. QCA6174 802.11ac Wireless Network Adapter [1a56:1535]


Kernel driver in use: ath10k_pci    


Kernel modules: ath10k_pci
uname -a
 </ code>

la sortie est:

dmesg | grep ath

la sortie est:
