我怎样才能解决这个问题?
答案1
我看到一些使用相同卡的用户遇到了同样的问题(安装 Broadcom 无线驱动程序)
一个已知问题是 jockey(也称为附加驱动程序)为一些 Broadcom 卡推荐了错误的驱动程序。
请打开终端并运行并发布:
sudo apt-get install --reinstall bcmwl-kernel-source
完成后,执行以下操作:
sudo modprobe wl
如果没有错误或警告,您的无线设备应该可以正常工作。
OP 表示需要额外的步骤才能使此解决方案发挥作用。见下文
完成这里的所有步骤后,我还必须另外安装 b43 固件包,如下所示:
sudo apt-get install firmware-b43-installer
重启后它就可以正常工作了。
