I figured it out, Davide!
Mr. Banana and I are in complete agreement that the next thing you need to do
is see what happens when you disable your wifi.
I was just too tired and stressed out to understand what he was saying.
Editing the configuration files which I posted upthread is how I personally
disable proprietary wifi cards but it isn't the only possible option for
disabling wifi cards in Trisquel.
I need to get some sleep before I log into my account again. My bad, just me
being me again, carry on.
