我最近从一位朋友那里得到了一台 Satellite A665，他当时想处理掉他的东西。我做的第一件事就是尝试安装 Ubuntu 14.04，它运行起来和过去一样顺利。但我无法让 wifi 工作。它说一个硬件开关禁用了它，但我已经按了 FN+F8 来解除阻止，但无济于事。然后我进入终端并输入“rfkill unblock all”，但没有任何变化。然后我将“iwconfig”输入终端，看到我有一个 wlan0 接口，但它不起作用。我看到了 eth0、l0 和 wmx0，但它显示“没有无线扩展”。我在网上查了一下，发现我需要一些驱动程序来支持我的 wifi 卡，但从那时起，我完全不知道该怎么做。lshw -c netwrok 输出： lsmod 输出：

答案1
在 Toshiba A665 上，用于启用/禁用无线适配器的硬件触摸按钮（位于键盘顶部）实际上可以工作。因此，您可能只需按下它即可启用无线功能。
答案2
如果这与您的相同，则右侧电源按钮的第二个按钮（位于 F8 和显示屏之间）应该可以移除 rfkill 对 wifi 的硬阻止。我有一台具有类似设置的东芝笔记本电脑。FN 组合只能软阻止 wifi
