未列出 WiFi 网络;Ubuntu 20.04;Broadcom BCM4360

我无法在安装了 20.04 的笔记本电脑上使用 BCM4360 网卡查看任何 wifi 网络。有人能帮我吗?谢谢。

如果需要任何其他信息来帮助调试此问题,请告诉我

编辑:有趣的是,ubuntu 能够列出附近的蓝牙设备。

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

答案4

在 2021 年 8 月内核 5.11.0-25-generic 更新期间,博通 wifi 停止工作

清除并重新安装后它再次运行。
