[xubuntu-users] How to start a wlan connection when xfce is not running?

[Andreas Säger]

Hello experts,
I can not find a way to start my wlan connection from a console session 
or from a WindowMaker session.

I try:
> $ sudo ifup eth3
> ifup: interface eth3 not configured

where eth3 is the alleged name of my usual wlan connection that starts 
automatically with xfce.
Even with xfce running,
> sudo ifdown eth3
  complains about unconfigured eth3 although eth3 seems to be up and 
running:
> $ ifconfig eth3
> eth3      Link encap:Ethernet  Hardware Adresse 00:13:e8:03:bd:6b
