On Trisquel? I think your mistaken.
The N & G USB chipsets that are supported in Trisquel are:
RTL8187/RTL8187B/RTL8187L/AR9170 and AR9271/AR7010/AR9280 will be... shortly
(requires firmware install still, unless this changed, and I missed the
announcement, jxself?).
For N mini pcie / mini pcie half height wireless N cards Trisquel supports:
Most atheros chipsets and at least one broadcom (braodcom not advisable
though, developer disclaims its use, though some Trisquel users are using it,
soo... take that for what it is). There are some cards though I'd recommend
against due to a combination chipsets of which one chipset is dependent on
non-free firmware. There are other chipsets (non-N) from atheros which are
also very poor quality or lack power management support (from the G days).
Also of note is that all these cards are not necessarily supported (out of
the box anyway) which have these chipsets. Some cards use different IDs so
the drivers/firmware don't know to load.
I'm 99.995% confident there are no N Realtek chipsets supported under
Trisquel. They are all dependent on non-free software so unless you manually
installed something... it won't work. If you did manually install something
non-free I hope you understand that this was undesirable. It defeats the
purpose of going with a 100% free operating system. This is also something
this community would advise against. It is the one thing everybody agrees on
here.
