Jockey] has been removed from Trisquel because it helps users install
non-free software. If your wifi card isn't working off the bat it is
unlikely it will work out of the box without non-free software which we can
not recommend. We also can not recommend software that has the purpose of
downloading non-free software.
You have a couple options:
1) Check
[http://h-node.org/wifi/catalogue/en/1/1/undef/undef/yes/undef/undef/undef
h-node's (hardware database) list of wifi cards that work with all free
software].
2) Check out think penguin for a free software compatible card (see the link
on the right side of the website). If you buy a card through the link on
this website 10% of the profits are donated to the Trisquel project. Contact
user "chris" for more information as he runs thinkpenguin.
