无法在 18.04 中使用 Broadcom 有限的 BCM4350 802.11ac 无线网络适配器 [14e4:43a3] (rev 08)

无法在 18.04 中使用 Broadcom 有限的 BCM4350 802.11ac 无线网络适配器 [14e4:43a3] (rev 08)

我把无线网卡更换intel 8265DW1820a,但是我屏蔽了这张卡上的一些针脚。

硬件信息

跑步lspci -nn -d 14e4:

并检查bcmwl-kernel-source

$ sudo dpkg -s bcmwl-kernel-source
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.

然后重启:
