Ubuntu 10.10刚安装的时候硬件基本正常，除了声卡、HDMI问题。
使用两周，wifi也挂掉了。
找了N久没搞定~~
用网线两个月，年初二实在忍不住了，折腾了一下午。
[原因]Ubuntu upgrade的rfkill tool默认block了wifi模块
[解决]
rpeter@:~$ 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
rpeter@:~$ rfkill list
0: hp-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
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）
