如何让我的 HP Pavilion dv2000 笔记本电脑上的 Wi-Fi 运行？

我看到了很多关于同一问题的问题，但都找不到解决方案。我遇到了同样的问题，我的 wifi 在 Ubuntu 11.04 上无法使用，但在 Windows 7 上却可以完美运行。

答案1

该跟踪表明您的网卡已“禁用”。

当无线网卡有关闭开关时就会发生这种情况 - 这是一个物理开关或 Fn+ 类型的开关。

如果您没有识别交换机，请运行以下命令：

rfkill list

这应该将所有无线设备报告为“否” - 即未被阻止。

例如对于我的笔记本电脑，结果是：

0: acer-wireless: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

如果我的无线信号说“是”，那么我会运行：

sudo rfkill unblock acer-wireless; sudo rfkill unblock wifi; sudo rfkill unblock all

显然，用“acer-wireless”替换你的无线局域网名称，如下所示rfkill list
