I added an applet for wireless that came with kde and it shows me that the connection is ok but
at start of my laptop there a check up and then the led of my wifi goes up then it goes down!!
when i got to use the command
it just dies and the message is
Error for wireless request "Set Nickname" (8B1C) :
SET failed on device wlan0 ; Operation not supported.
Polling for DHCP server on interface wlan0:
No carrier detected on wlan0. Reducing DHCP timeout to 10 seconds.
dhcpcd: MAC address = 00:16:cf:8c:9f:27
it can't get an ip i think.
I hope it will helps
