我有一个大问题。
我刚刚在电脑(或笔记本电脑)上安装了 Ubuntu 19.04。但是,无线驱动程序不起作用。我检查了设置,但没有名为“Wi-Fi”的菜单。
笔记本型号:Acer Aspire E 11
以下是完整报告:

$ sudo modprobe wl
modprobe: FATAL: Module wl not found in directory /lib/module/5.0.0-13-generic
编辑:
在我重新安装 bcmwl-kernel-source 之后。基本就完成了。但是,我收到以下消息:
modprobe: ERROR: could not insert 'wl': operation not permitted
答案1
好的,在我按照@chili555的最后一条指示操作后。我尝试禁用安全启动,最后,我的无线驱动程序可以正常工作了。
