答案1
我刚刚升级到 12.04 Ubuntu，遇到了这个问题。这是我的rfkill list all输出：
shirish@shirish-Inspiron-1545:~$ rfkill list all
0: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes
1: dell-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes
2: dell-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
我现在该怎么办？我试过了，rfkill unblock all但是没有用。
