起初我安装了 32 位 ubuntu 12.10，在众多答案的帮助下，我费了好大劲才设置好 WiFi，后来我考虑安装 64 位，因为我的系统是 64 位的。在安装时，我找不到列出的任何 WiFi 名称，我通过有线连接。虽然我这里有 3 个 WiFi 在运行……但我无法在检查状态中看到启用无线，或者我在软件源的附加驱动程序选项卡中找不到任何 WiFi 驱动程序。
可能存在什么问题？这台笔记本电脑不能使用 Ubuntu 的 WiFi 吗？
虽然我使用 ubuntu 大约有 1 年了，但我没有使用 ubuntu 进行任何故障排除的经验。

显示，设备已检测到并准备就绪。但被硬阻止。这意味着控制 wi-fi 的硬件开关已关闭。请将其打开。如果是 Fn+F<1-12> 键，请测试这些键在 Linux 下是否正常工作。
也可以尝试不用 Fn 键（如果 F2 是用于 wi-fi 的，则只使用 F2）。
