![如何让我的 HP Pavilion dv2000 笔记本电脑上的 Wi-Fi 运行?](https://linux22.com/image/1075760/%E5%A6%82%E4%BD%95%E8%AE%A9%E6%88%91%E7%9A%84%20HP%20Pavilion%20dv2000%20%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%E4%B8%8A%E7%9A%84%20Wi-Fi%20%E8%BF%90%E8%A1%8C%EF%BC%9F.png)
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
