Here are my settings. I am trying to get my WLAN up and running. I have this in /etc/network/interfaces:
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
mapping eth0
script grep
map eth0

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp
up wpa_supplicant -ieth1 -c/etc/wpa_supplicant.conf -Bw
down killall wpa_supplicant
=======================================

But when I run iwconfig it is not picking up the infomation.

eth1 unassociated ESSID:"soby"
Mode:Managed Channel=0 Access Point: Not-Associated
Bit Rate=0 kb/s Tx-Power=20 dBm
Retry limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
========================================

I have the correct WPA key set up in wpa_supplicant.conf

How do I tie all of this together. Setting up my eth1 card to have the correct essid/channel/accesspoint/encryption/dhcp......

Thanks,
