The Trisquel community is not in favor of open source. It is in favor of free
software: https://www.gnu.org/philosophy/open-source-misses-the-point.html
It make all the difference here. Our recommendation simply is to acquire a
Wifi device that Linux-libre (hence Trisquel) can drive. The easiest way is
to buy a USB adapter at http://libre.thinkpenguin.com (using this link, 25%
of the benefits on your purchase will be donated to the Trisquel project) or
at http://tehnoetic.com
Those are the only two vendors that guarantee that their hardware work with
Linux-libre. If the vendor indicates the chipset, the second-hand market is
an option as well. Other shops, even physical ones, are useless because the
chipset (what matter) is never indicated and a same model can be sold with
different chipsets. That even is why the chipset is not written on the
wrapping.
