[WIFI] Connection impossible

[SCHRODER Emmanuel]

Hi,

It's been weeks since I'm fighting with my laptop to get my wifi working at
school... with no success so far. I gave up on mandrake, and then I changed
to ubuntu. I like so far, especially since it includes my wifi card module.
My wifi card is a Intel Pro 2200 BG.  But it still doesn't work.

Here is how I installed it:
First I checked that the module was loaded 

spiritz at linux:~ $ lsmod | grep ipw 
ipw2200 108652 0 
firmware_class 9728 1 ipw2200 
ieee80211 21124 1 ipw2200 

Everything seems to be ok, now I configure the card
iwconfig eth1 essid "ReiMS" 
iwconfig eth1 key s:XXXXXXmClefWepxxxxxxxxxxxx open 

Then I make sure that everything is set
spiritz at linux:/etc/network $ sudo iwconfig eth1 
eth1 unassociated ESSID:"ReiMS" Nickname:"Spiritz" 
Mode:Managed Channel=11 Access Point: 00:0E:D7:C2:0A:A0 
Bit Rate=0kb/s Tx-Power=20 dBm 
RTS thr:off Fragment thr:off Encryption key:3143-4142-4132-4641-4341-4445-33
Security mode:open 
Power Management:off 

In order to check that it's working at least for scanning, I typed "iwlist
eth1 scan". I got results (weird fact: all the ESSID are set to <hidden>".

Now, big time, I try to connect.
spiritz at linux:/etc/network $ sudo ifup eth1 
Error for wireless request "Set Bit Rate" (8B20) : 
SET failed on device eth1 ; Operation not supported.

>> With no success, I got no Ip address.. (Note: It works fine under windows
xp)

I really don't have a clue why it's not working. Does any one here has a
clue?
