[Linux] Ubuntu How to enable wireless

我在ubuntu將wifi功能disable掉, 然後竟然無法直接透過UI的介面將wireless enable起來….
稍微google了一下, 下面的方式可以成功

首先試試看最基本的方式..
看來無效

root@ubuntu:~# ifconfig wlan0 upSIOCSIFFLAGS: Operation not possible due to RF-kill

列出無線裝置

root@ubuntu:~# rfkill list0: sony-wifi: Wireless LAN Soft blocked: yes Hard blocked: no1: sony-bluetooth: Bluetooth Soft blocked: no Hard blocked: no2: hci0: Bluetooth Soft blocked: no Hard blocked: no3: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes

把wifi unblock吧~
再看看裝置是否ok了

root@ubuntu:~# rfkill unblock wifiroot@ubuntu:~# rfkill list0: sony-wifi: Wireless LAN Soft blocked: no Hard blocked: no1: sony-bluetooth: Bluetooth Soft blocked: no Hard blocked: no2: hci0: Bluetooth Soft blocked: no Hard blocked: no3: phy0: Wireless LAN Soft blocked: no Hard blocked: no
