Is that a 3Com Airconnect Card? as in  
http://www.seattlewireless.net/index.cgi/AirconnectComments 
 
Thats a prism chipset card according to the following link 
http://www.linux-wlan.org/docs/wlan_adapters_supported_html2.html 
 
AFAIK There are (were) 2 major chipsets in the 802.11b cards, the hermes 
chipset for Lucent orinoco cards and similar, and a the Prism chipset for lots 
of other cards.  The chipsets seem to have diversified recently but I think 
you've got a Prism chipset there. 
 
The hermes chipset used the wvlan driver , which has been superceded by the 
orinoco driver, (see http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/ ) 
whilst the prism chipset used the wlan_ng driver (see 
http://www.linux-wlan.com ) 
 
There are different tools to manage the config of the cards, the orinoco 
driver using the wireless tools packages whilst the wlan_ng driver using some 
configuration files in /etc 
 
 
I _think_ that the later versions of orinoco driver could drive the prism 
chipset also, giving a consistent toolkit to manage wireless devices with ..  
but that _might_ depend on having the correct firmware on the prism chipset .. 
I don't know, :( 
 
 
for your particular card,

(The site seems to be down but google cache come to rescue) 
this seems to suggest you need the plx driver rather than the pci / or pcmcia 
driver for the card, and has a howto.  You can probably deal with the spanish 
better than me :) 
 
Why is hardware so difficult on Linux ?
