networkmanager and WEP shared keys problem

["Amadeu Júnior" <amadeu gmail com>]

hi guys,

I'm using the networkmanager from a Debian testing installation
(0.6.5-3) and I don't have tested with the svn version of the
networkmanger, but I have a problem with shared keys wep authentication.

When I try to use the nm-applet to fill the pass with "shared keys"
option the NetworkManager try:

Jan 14 10:09:47 sarang NetworkManager:   Activation (eth2) Stage 1 of

Until ok! But I got:

Jan 14 10:10:48 sarang NetworkManager:   Activation (eth2/wireless):
association took too long (>60s), failing activation.

or (in other attempt):

Jan 14 11:26:27 sarang NetworkManager:   Device 'eth2' DHCP
transaction took too long (>45s), stopping it.

I was reading some links, but I don't see a solution:

http://mail.gnome.org/archives/networkmanager-list/2005-August/msg00140.html

So I tested wpa_supplicant by the hand:

1. created a file "test.conf":
ctrl_interface=/var/run/wpa_supplicant
network={
       ssid="impa-wl"
       key_mgmt=NONE
       auth_alg=SHARED
       wep_key0="mypassword"
       wep_tx_keyidx=0
}
2. executed the command:
# wpa_supplicant -i eth2 -d -c /home/amadeu/test.conf

and.. it works and the dhclient works fine too :)

My wpa_supplicant log is :

My essid is "imap-wl" of the WEP 128-bits with shared keys option. I
don't know which the AP model. My wireless card is a Broadcom 43xx.
And my iwconfig eth2 output show:

Someone could help me? :)

Thanks a lot and sorry for my poor english :)
