Inspiron 15 5570 上的 ubuntu 14.04 没有 Wifi

我使用的是 Dell Inspiron 15 5570 笔记本电脑。我有 Windows 10 和 Ubuntu 14.04 LTS（双操作系统）。单击 Wifi 图标时未列出 Wifi 启用选项。在 Windows 10 中，Wifi 运行正常。

网络控制器：Qualcomm Atheros 设备 [168c:0042]（rev 31）。

命令结果dmesg | grep ath：

命令结果sudo dpkg -s linux-firmware | grep Version： Version: 1.127.24

有什么帮助吗？

您需要更新的固件！在网络连接正常的情况下，请打开终端并执行以下操作：

cd /tmp
sudo wget http://security.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.169.1_all.deb
sudo dpkg -i linux*.deb

重新启动后你的无线网络就能够正常工作了。
