无线被硬件开关禁用。Wifi 无法使用！（硬屏蔽：是的，联想 Y580，Ubuntu 13.10）

我的笔记本电脑联想 Ideapad Y580 的 wifi 有问题（购买时预装了 Windows 7 Home Premium 64 位）。卸载 Win7 并安装 Ubuntu 13.10 64 位（正常有线互联网可以使用）后，wifi 无法使用！

无线已被硬件开关禁用。

rfkill 列出全部

martin@martin-Y580:~$ rfkill list all
0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

我检查了 BIOS，发现无线网卡已在那里启用。

Fn + F5 不起作用，而且我的电脑外面没有物理开关，这就是我在这里询问的原因。

rfkill unblock all仅更改软块，并向sudo ifconfig wlan0 up我显示以下内容：SIOCSIFFLAGS: Operation not possible due to RF-kill。

一些规格：

我该如何解决这个问题？

答案1

对于我的联想 Thinkpad 来说，这是有效的。

在终端中输入此内容（可以使用Ctrl+ Alt+打开t）：-

sudo nano /etc/modprobe.d/blacklist.conf

并在该文件末尾添加以下内容：-

黑名单 ideapad_laptop

然后保存文件。

现在重新启动。

答案2

这对我的 Lenovo Miix 2 11'' i5 有效：

您可以通过以下方式暂时禁用 ideapad_laptop

sudo modprobe -r ideapad_laptop

如果你的 WiFi 现在可以使用，你可以克里斯德布里的解决方案

答案3

上述解决方案对我（HP 6910p）不起作用。我最终找到了一个 YouTube 视频，视频中一个人将 BIOS 恢复为默认值，保存，然后正常启动。我不相信这么简单的事情会起作用，但我很绝望。无论如何，它起作用了！我想知道为什么这个错误还没有修复……有很多文章致力于尝试解决这个问题！

答案4

有些笔记本电脑有 Fn 键（红色），可以使用 Fn 键与功能键（通常是 F5）组合来禁用或启用 wifi。

尝试这样做。
