wireless connection with fluxbox via commands

Hi,
By default I use all gnome stuff (gdm+metacity+...) and my connection works well.
I wanted to try fluxbox. So I've just changed my window manger. And under fluxbox, wireless isn't managed automatically like with gnome.
So I tried to set it up manually ... but I can't make my wireless connection work via commands :s

The easy way would be to launch the gnome network manager application:

nm-applet&

and my connection works ... so I don't think the trouble comes from the driver.

But via commands I'm stuck.
here is what I've done :

iwconfig wlan0 key open
iwconfig wlan0 essid "NEUF_595C"
dhclient wlan0

according to my iwconfig output I think it's alright

$ iwconfig wlan0

wlan0     IEEE 802.11abg  ESSID:"NEUF_595C"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated   
          Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

--------------EDIT---------------
Ups ... I've not noticed that I hadn't access point >< ... very strange ...
So I've tried to force it :

iwconfig wlan0 ap 00:17:33:57:59:60

but the iwconfig output stays the same :confused: .... access point still not associated ...damned...
-------------- END OF EDIT---------------

$ ifconfig wlan0 192.168.1.65/24
$ route add default gw 192.168.1.1

$ ifconfig wlan0

But I still can't ping :confused:
I'm stuck and doesn't understand why ... some help would be very welcome :slight_smile: thx
