尝试使用这个:安装 Broadcom 无线驱动程序,但未列出 [14e4:43a3] (rev 08)。
以下是相关输出: sudo lshw -C network
*-network UNCLAIMED
description: Network controller
product: BCM4350 802.11ac Wireless Network Adapter
vendor: Broadcom Limited
physical id: 0
bus info: pci@0000:3a:00.0
version: 08
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress cap_list
configuration: latency=0
resources: memory:dc400000-dc407fff memory:dc000000-dc3fffff
我以为是内核问题,但是输出如下:uname -r
4.4.0-109-generic
无线网络最近可以正常工作,但是在更新期间我认为发生了一些事情。
有什么想法吗?我尝试过https://help.ubuntu.com/lts/ubuntu-help/net-wireless-troubleshooting.html,但无济于事。感谢您的帮助。

运行sudo dpkg -s bcmwl-kernel-source
并得到:
dpkg-query: package 'bcmwl-kernel-source' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.
无论如何,我都进行了清除。
真的不知道我做了什么,但现在它可以正常工作了。也许我在这一切发生之前做了更改,只需要重新启动?
无论如何,感谢您的帮助,我希望写一些东西以防其他人遇到同样的问题。
答案1
我不完全确定是什么解决了这个问题,但清除 bcwl-kernel-source 并重新启动似乎可以解决问题。
