Problem with Wlan & ipw2100

hey ho, actually i don't know if thats the right part of the forum to post but well, you never know

my girlfriend got herself a thinkpad t42 and she wanted to use the wlan card, so thats what i tried to get to work for the last hours...
i got myself a t41 whichs wlan works fine (but under gentoo)
long term short story:

lspci |grep Wireless >> Network controller: Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04)
hwd -e says: ipw2200 : Intel Corp. | PRO?Wireless LAN 2200
k, somewhere in the forum was written that that's a hwd bug so i tried the ipw2100-fw package

reboot and the wlan led starts blinking,
so i thoughts just gotta conf wpa_supplicant:

 network={
ssid="myessid"
key_mgmt=NONE
priority=10
}

and create a network-profile
/etc/network-profiles/wlan:

DESCRIPTION="Default Wlan"
INTERFACE=eth1
HOSTNAME=myhost

IFOPTS="dhcp"

USEWPA="yes"
WPAOPTS="-D ipw"

and to finish it i edited the rc.conf:

MODULES=(thinkpad ipw snd_intel8x0 e1000 snd-pcm-oss)

eth1="dhcp"
...
INTERFACES=(lo eth0 eth1)

NET_PROFILES=(wlan)

while starting /etc/rc.d/network i get just a  Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory

so actually i'm used to the gentoo configuration (put a modules_device=( "wpa_supplicant" ) here, and a wpa_supplicant_device="-Ddriver" there and it works
so if there would be an equivalent for arch...
would be great

so i'd be glad for everyhelp i could get

ps:

wpa_supplicant -c /etc/wpa_supplicant.conf -i eth1 -D ipw >> ioctl[IPW_IOCTL_WPA_SUPPLICANT]: Operation not supported < -a few times
wpa_supplicant -c /etc/wpa_supplicant.conf -i eth1 -D wext >> Trying to associat with MA:C0:AD:RE:SS (SSID='myessid' freq=1234 MHz)
ioctl[SIOCSIWFREQ]: Operation not supported
Association request to the driver failed
Authentication with 00:00:00:00:00:00 timed out. <- and again and again

Re: Problem with Wlan & ipw2100

I'm using the ipw2200 driver, and i haven't tried ipw2100 , but i can imagine they are roughly the same to setup.  I don't have a direct answer to the question you're posing, but here's my /etc/rc.conf.

I use the gnome-network-manager applet to connect to any network. pacman -S gnome-network-manager. Run it using nm-applet &

MODULES=(tg3 ipw2200 <---- ac97_bus snd-mixer-oss snd-pcm-oss snd-page-alloc snd-pcm snd-timer snd snd-ac97-codec snd-intel8x0 snd-intel8x0m soundcore acpi-cpufreq)
# Scan for LVM volume groups at startup, required if you use LVM
USELVM="no"

eth0="dhcp"
eth1="dhcp"   #Wireless interface
INTERFACES=(lo !eth0 !eth1)
WLAN_INTERFACES=(!eth1)

#
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
#   - prefix an entry in ROUTES with a ! to disable it
#
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)

...

Hope that's of some help.

Re: Problem with Wlan & ipw2100

ok with the rc.conf changed to the points you gave and without any network-profile its possible to connect with dhcpcd eth0 to the wlan, but how can i manage wpa_supplicant that way?

Re: Problem with Wlan & ipw2100

Please try netcfg2. It's much simpler.

For the hwd thing, yes, it's a bug, you'll need ipw2100-fw. And the kernel module for the modules line is ipw2100, though udev has probably autodetected and loaded it for you.
