Help on Wireless Networking

I'm having trouble with getting wireless network to install on my IBM
Thinkpad T23.

I have a Linksys WPC11 V3 PC Wireless PC Card.  The output for cardctl ident is:

Socket 0:

PC Card", "ISL37300P", "RevA", manfid: 0x0274, 0x1613 funcation: 6

/etc/network/interfaces is automatically configured by network
settings window found in computer->system configuration->networking

iface wlan0 inet static

gateway 192.168.1.1

When I run the ifup wlan0 command, I get this error:
