我的电脑 16.04 上未显示 Wifi

我的 Ubuntu 16.04 笔记本电脑上未列出 Wifi 网络。我在这里看到了很多类似的帖子，但没有人提供帮助。

这是我在终端中收到的错误：

wlan0     Interface doesn't support scanning.

列表的输出 lspci -knn | grep Net -A3; rfkill是：-

您需要更新您的linux-firmware。似乎未启用更新软件源。

转到系统设置->软件和更新并启用所有来源。

通过有线方式连接到互联网，系统会建议更新源，然后运行

sudo apt upgrade

系统将获得更新，并且重启后 Wi-Fi 应该可以正常工作。
