Airport and WEP

[Arnaud FONTAINE <arnaud.fontaine@free.fr>]

Hello,

I've recently installed an Airport Extreme access point in my network; and an
Aiport card (NOT the extreme one) in my iBook(first generation) with Debian
testing/unstable with a 2.6.1 kernel. Everything works fine if I do NOT use WEP,
as you can see:

#dmesg

orinoco.c 0.13e (David Gibson <hermes@gibson.dropbear.id.au> and others)
airport.c 0.13e (Benjamin Herrenschmidt <benh@kernel.crashing.org>)
Airport at physical address 80030000
eth1: Station identity 001f:0001:0008:0046
eth1: Looks like a Lucent/Agere firmware version 8.70
eth1: Ad-hoc demo mode supported
eth1: IEEE standard IBSS ad-hoc mode supported
eth1: WEP supported, 104-bit key
eth1: MAC address 00:30:65:0F:11:6D
eth1: Station name "HERMES I"
eth1: ready
airport: card registered for interface eth1
eth1: New link status: Connected (0001)

          Interrupt:57 


If I enable WEP encryption (with a valid 26 hex digits key), I do not obtain the
network connection on my iBook, although it works fine with OS X.

Here is eth1 related part from /etc/network/interfaces

iface eth1 inet dhcp
        pre-up modprobe airport
        post-down modprobe -r airport
        client post.air
        wireless-essid air.bjork
        wireless-nick post.air.bjork
        wireless-power all
        wireless-sens 1
        wireless-frag auto
        wireless-enc aaaa-aaaa-aaaa-aaaa-aaaa-aaaa-aa


Does someone know where it can come from ?
