我正在使用 compaq presario v 3000 tu 笔记本电脑。
今天我安装了 12.04 ubuntu。但很遗憾我无法通过 wifi 连接。对我来说，没有 wifi 就没用。尝试了很多网上发布的命令，但无法解决问题 ---
运行 Runtil wlan manager 时出现此错误 -
*严重错误：找不到任何无线网络接口。代码：-3*
请帮忙..
以下是我在我的系统上运行的命令的输出..

答案1
在终端中尝试以下操作：
sudo apt-get install firmware-b43-installer
如果您的卡较旧，您可能需要尝试旧版安装程序，您可以通过输入以下内容来执行此操作：
sudo apt-get install firmware-b43legacy-installer
祝你好运！
