PCMIA Wireless Card won't Connect to Internet

[Donald Metheny]

Having problem getting my Linksys WPC 11 (Ver.3) to connect to the
internet. Ran iwconfig and got the result shown below. This shows the
access point as none.

eth1      IEEE 802.11b  ESSID:"xxxxxxxxxxxx"  Nickname:"Prism  I"
          Mode:Managed  Frequency:2.437 GHz  Access Point: None   
          Bit Rate:2 Mb/s   Sensitivity:1/3  
          Retry limit:8   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=0/92  Signal level=-68 dBm  Noise level=-122 dBm
          Rx invalid nwid:0  Rx invalid crypt:33  Rx invalid frag:0
          Tx excessive retries:66  Invalid misc:0   Missed beacon:0

I then ran: sudo iwconfig eth1 essid <xxxxxxxxxxx> ap
<xx-xx-xx-xx-xx-xx> key <xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx> mode <>
commit

I got the following response:

Interface eth1 doesn't support IP addresses
eth1      Interface doesn't support IP addresses
Error for wireless request "Set AP Address" (8B14) :
    invalid argument "xx-xx-xx-xx-xx-xx".
I'm certain of the essid, ap and key as I got those off an ipconfig/all
inquiry. Where do I go now??
