Wireless configuration files

Hello,

I`m trying to configure a wireless Symbol Sprectrum CF card, I edited
these files:

################################
       
/etc/network/interfaces

# The loopback interface
# automatically added when upgrading
auto lo
iface lo inet loopback

# The first network card
# automatically added when upgrading
auto eth0
iface eth0 inet static
address 10.30.1.199
netmask 255.255.255.0

#Wireless Card
auto eth1
iface eth1 inet static
address 10.30.1.54
netmask 255.255.255.0
wireless_essid P320
wireless_mode Managed
wireless_rate auto

#################################

/etc/pcmcia/wireless.opts

case "$ADDRESS" in
*,*,*,00:A0:F8:5F:51:07)
    INFO="Default Config"
    ESSID="P320"
    MODE="Managed"
    RATE=auto
    ;;
esac

##################################

With this configuration the card doesn´t work.
Did I forget anything?? If someone can help me, I need more
Information about configuration files.

Thank in advanced
