如何使 Atheros Communications Inc. AR9285 无线网络适配器工作？

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.

wlan0     IEEE 802.11bgn  ESSID:off/any

          Power Management:off

eth0      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：

$ sudo lshw-类网络

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。
