Ubuntu Networking without Gnome?!

Hello everyone,

I bet this would be a nice tutorial for others too..
I have a problem, sometimes I would like to use only commanline so I have disabled gdm autostart, but the thing is that wireless network isn't working..
How wireless should be configured by hand?

Thanks!

 

That all depends on whether you are connecting to an open or WEP encrypted accesspoint, or if you are connecting to a WPA encrypted accesspoint.

Open accesspoint :
sudo iwconfig wlan0 essid name_of_accesspoint <enter>
sudo ifconfig wlan0 up <enter>
sudo dhclient wlan0 <enter>

WEP encrypted accesspoint :
sudo iwconfig wlan0 essid name_of_accesspoint key s:encryption_key_of_accesspoint <enter> (If you only have the encryption key in hex, then omit the "s:" part)
sudo ifconfig wlan0 up <enter>
sudo dhclient wlan0 <enter>

WPA encrypted accesspoint :
sudo wpa_passphrase name_of_accesspoint encryption_passphrase_of_accesspoint >> /etc/wpa_supplicant.conf <enter>
sudo ifconfig wlan0 up <enter>
sudo wpa_supplicant -iwlan0 -Dwext -c/etc/wpa_supplicant.conf <enter>
sudo dhclient wlan0 <enter>


Remember NOT to have NetworkManager running. ( sudo /etc/init.d/NetworkManager stop<enter> )

 

great, many many thanks DutchDK!
I will try that one out when I get back to home!

 

You're welcome, revert back with the results, as the above was written from memory.

 

Hi,

So according my tests it doens't work
sudo wpa_supplicant -iwlan0 -Dwext -c/etc/wpa_supplicant.conf <enter> with proper parameters says:

Trying to associate with XX:XX:XX:XX:XX:XX(proper mac address here) (SSID='ssid or wlan' freq?2437 MHz)
Associated with 00:00:00:00:00:00
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
ioctl[SIOCSIWENCODEEXT]: No such file or directory

Also if I wrote: /usr/local/bin/acer_ec.pl get wireless
it returns " Wireles off "

And wlan on / off button at front of the laptop doens't work either..

Any advises?

 

Did you stop NetworkManager ?
Also, it looks like I forgot to add the parameter for sending wpa_supplicant to the background, so try to add a -B to the wpa_supplicant command.
