安装无线驱动在终端中运行以下命令来安装驱动:
sudo apt-get 更新
sudo apt-get 安装 bcmwl-kernel-source
安装完成后,重新启动计算机并检查无线适配器是否正常工作。
尝试手动加载驱动程序模块如果上述步骤不起作用,请尝试使用以下命令手动加载驱动程序模块:
sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
sudo modprobe wl

2021 年 1 月,在 Ubuntu 20.04 更新后,我的 MacBook Air 2015 上的网络停止了。
以下是我如何让它再次运行的总结:
Enable the use of proprietary drivers. For example in 'Software & Updates / Ubuntu Software'
sudo apt update
sudo apt remove --purge bcmwl-kernel-source
sudo apt install --reinstall broadcom-sta-dkms
Reboot you computer
答案3
使用该驱动程序: https://github.com/antoineco/broadcom-wl/tree/patch-linux4.7
/etc/modprobe.d/blacklist.conf
# wireless drivers (conflict with Broadcom hybrid wireless driver 'wl')
blacklist ssb
blacklist bcma
blacklist b43
blacklist brcmsmac
为正在运行的内核构建并安装:
$ make
$ make install
$ depmod -A
$ modprobe wl
