4楼那个版本得驱动不稳定，前几天装linux就被无线网卡卡住了。
我的电脑用的就是rtl8192cu的usb无线网卡。
0.36,0.37的驱动都不好，离远了连不上，windows能连。
去大便官网下0.38的firmware-realtek。这个我还没试验。

无线网卡好解决，我也是今天才解决的，不过我用的6，debian7有点不爽，
你先看看sudo gedit /etc/NetworkManager/NetworkManager.conf
把managed=false 改true;
然后firmware-iwlwifi_0.28+squeeze1_all.deb，百度一下，这个名字，第一个就是连接，下载合适的版本，我是64的，就用的amd64，下完安装即可。
重启电脑。开机可以看到无线了。
