你好,请教一下 ubuntu,我的无线网不能用,以下是我的信息:系统使用:联想 Z570
$ iwconfig
lo no wireless extensions.

$ sudo ifconfig

wlan0 is not showing in thils , but now when i try to use.
$ sudo ifconfig wlan0 up
SIOCSIFFLAGS:由于 RF-kill,无法进行操作
现在当我使用它时:
$ sudo rfkill 列出全部
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
2: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
4: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
然后我使用命令:
$ sudo rfkill 解除所有阻止
然后 :
$ sudo rfkill 列出全部
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
2: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
4: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
这里phy0 硬阻塞 = 是
结果是一样的(然后我再次尝试通过按 Fn+F5 从键盘打开/关闭 wifi)
$ sudo rfkill 列出全部
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: yes
2: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
4: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
现在这个时候phy0 软阻塞 = 是,硬阻塞 : 是
以下是硬件规格:

答案1
我也遇到了同样的问题。我通过按下Fn+F2
键盘上的 解决了这个问题。按下Fn
带有 wifi 符号的键。它将硬阻止设置为“否”
答案2
我在使用联想 IdeaPad N585(同样是 Atheros 卡)时也遇到了同样的问题,其中硬阻断只能通过 Windows 中的能源管理软件进行控制。一旦在 Windows 中启用它,它似乎会在整个重新启动过程中保持不变,因此我只需在 Windows 中启用它一次即可。
