无法识别有线或无线连接

我刚刚在我的一台旧笔记本电脑上安装了 ubuntu 13.04，但无法连接到互联网。该电脑是戴尔 Vostro 1500。

这是我第一次使用 Linux，所以我真的不知道自己在做什么，但我正在努力学习。

我知道这篇文章可能已经发布了很多次，但看完几篇之后，我找不到任何有同样问题的帖子

转到此链接，司机在8号岗位。b43.zip

将 b43 zip 文件下载到闪存驱动器，然后将文件拖放到您的 ubuntu 桌面。右键单击它并选择在此处提取。打开终端并执行：

sudo mkdir /lib/firmware/b43

sudo cp Desktop/b43/* /lib/firmware/b43

sudo rmmod -f b43

sudo rmmod -f ssb

sudo modprobe b43

如果您尚未安装任何其他无线驱动程序，您的无线现在应该可以正常工作。

这些说明适用于在没有互联网连接的情况下安装驱动程序

您安装了另一个驱动程序，因此我们需要将其删除。

sudo apt-get purge --remove bcmwl-kernel-source

然后：

sudo modprobe b43
