Hello I'm a very new user in unix systems. I installed ubuntu 64 bit 12.04 LTS on my macbook pro 4,1 early 2008. I fix the problem in ubuntu with the wifi but always if I wanted to connect to wifi I have to connect to random hidden network to show my network is complicated I know. I installed kubuntu and now the wifi does not work. I cant see my wifi connection and when I tried to connect as hidenn via konsole:
boo@boo-MacBook:~$ iwconfig wlan0 essid sarmale key 2358085701Error for wireless request "Set ESSID" (8B1A) :
SET failed on device wlan0 ; Operation not permitted.
boo@boo-MacBook:~$ dhclient wlan0
RTNETLINK answers: Operation not permitted
iwconfig: eth0 no wireless extensions.
lo no wireless extensions.
wlan0 IEEE 802.11bg ESSID:off/any

Thank you I really need help I don't know what to do anymore this problem is bothering me since last week.
