新装的UBUNTU 11.10无法启动无线

[lulz1003]

点了右上角的启用无线的勾之后想用无线上网，发现没打开无线网络
之后再看了下右上角的勾。。。发现自动取消了。。。用IWCONFIG查看得到这个。。。

　　[email protected]:~$ rfkill list

　　0: hp-wifi: Wireless LAN

　　Soft blocked: yes

　　Hard blocked: yes

　　1: phy0: Wireless LAN

　　Soft blocked: yes

　　Hard blocked: yes

　　rfkill unblock all 干掉所有软件block

　　[email protected]:~$ rfkill list

　　Hard block 问题： Fn+F2 解决 (明明laptop有wifi的硬件开关，Linux还是默认这对冤家当硬件开关)

2楼真的假的?

2次实验结果，不敢独享！
补充一点：/etc/NetworkManager/NetworkManager.conf内面设置改manager=true先
