Wireless PCMCIA - which one

[yoda2 <yoda2@yoda2.xs4all.nl>]

Dear all,

I've been gathering information about Wireless LAN's. This this is 
totally new for me, i have some "experience"-questions for the lucky 
ones owning a wireless pcmcia & acces point:
1) In the Netherlands "sitecom" is a very popular brand. These wireless 
PC-cards support IEEE 802.11b. However, has anyone experience with these 
cards under GNU/Linux?
2) Furthermore, I wonder, if I use ssh over the wireless LAN to connect 
to my server to login in as root; is it possible to "snif" the wireless 
communication-line and extract the root password in any manner? Thus is 
the wireless communication-line "ssh-encrypted"?
