环境: ubuntu 15.04

网卡:atheros ar9485

终端:

~$ sudo rfkill list all
0: acer-wireless: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

删除acer_wmi

~$ sudo rmmod acer_wmi 

到此已经可以正常启用WiFi,   但是重启之后发现又不可用,解决方法:

编辑 /etc/modprobe.d/blacklist.conf  添加下面内容

blacklist acer_wmi
