无法在 Ubuntu 16.04 LTS 上启用 Alienware R2 的 wifi

无法在 Ubuntu 16.04 LTS 上启用 Alienware R2 的 wifi

我刚刚在 Alienware 15 R2 笔记本电脑上安装了 16.04 LTS,可以通过以太网电缆连接到互联网,但 Wi-Fi 连接丢失。我尝试了发布在这里这里这里但都不起作用。以下是我发现人们需要作为详细信息的一些 ant 输出命令。

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

输出有两部分:

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

output is:
