Lubuntu Desktop/Sever Wifi Configuration
Abstract
This tutorials is about Lubuntu Desktop/sever wifi configuration on CB1、CB2 and CB3(Cubietruck).
Cubieboard1 and Cubieboard2 Lubuntu Desktop/sever USB WLAN card driver module:8188eu and 8192eu.
Cubietruck support Wifi wireless connection with antenna on-board,driver module is bcmdhd.
" Mw150us + 8188eu" USB WLAN card was tested on CB1 and CB2 on Desktop/sever.
Cubieboard Lubuntu Sever
Install wifi tool:apt-get install wifi-radar,then ,rebooting CB1 and CB2 only with USB WLAN card ,rebooting CT without network Cable,it will take a few minutes.
1.Install wifi-radar
apt-get install wifi-radar
Rebooting you can see this

5.Geting your WLAN IP,if you can`t go on after "dhclient wlan0",please reboot and do the previous 1-4 steps again
root@cubieboard:~# dhclient wlan0
