我花了一整天试图解决这个问题，但没有结果。我使用的是 elementaryOS Luna，但由于它在 Ubuntu 上运行...
我遇到的问题是，我的 Dell Vostro 1500 的以太网有问题。由于某种原因（很可能是硬件问题），它无法连接到以太网，因此我需要在安装驱动程序的计算机上安装没有互联网的驱动程序。
任何需要第二台 Linux 电脑的解决方案都行不通。这是从 OS X 输入的，而我拥有的另一台电脑就是有问题的电脑。
运行lspci我得到：

我知道我需要b43固件设置或其他东西，但我似乎找不到任何适合我使用的说明。
如果您需要任何其他信息来帮助我，请告诉我，我会尽力提供。
PS：为了获取命令的输出，我将命令的输出传输到 USB 中的文本文件，然后从正在运行的计算机中复制粘贴到这里。

请将此文件下载至同一个 USB 密钥并将其传输至您的桌面。https://dl.dropboxusercontent.com/u/58267392/b43_new.zip右键单击它并选择“在此处提取”。现在，在终端中：
sudo mkdir /lib/firmware/b43
sudo cp Desktop/b43_new/* /lib/firmware/b43
sudo modprobe -r b43 && sudo modprobe b43
可能需要重新启动。
