如何在HP Pavilion dv2000笔记本电脑上使用wifi？
我已经看到很多关于同一问题的问题，但无法得到解决方案。 我面临同样的问题，我的无线网络在Ubuntu 11.04中无法运行，但在Windows 7上运行良好。

当无线卡有一个开关将其关闭时会发生这种情况 – 这可能是物理开关或Fn +型开关。
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，结果如下：
0: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no
如果我的无线电话说“是”那么我会跑：
sudo rfkill unblock acer-wireless; sudo rfkill unblock wifi; sudo rfkill unblock all
显然，将“acer-wireless”替换为无线LAN的名称，如rfkill list所示
