从 12.10 升级到 13.04 后出现无线适配器问题

从 12.10 升级到 13.04 后出现无线适配器问题

在我使用了这两个命令后,我的无线适配器可能就可以正常工作了:

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43 && sudo modprobe b43

但是当我升级到 13.04 时,命令:

sudo modprobe -r b43 && sudo modprobe b43

...不起作用。我运行了lshw -C network

lshw -C network

请帮帮我。

wl适配器的驱动程序当前已加载,您需要先将其删除:

sudo apt-get purge broadcom* bcmwl*

该卡的固件安装方式如下:

sudo apt-get install firmware-b43-installer

重新启动后,b43适配器的驱动程序应该会加载,您可以使用它来检查lshw -C network
