According to yourself, you asked the question because several wifi cards
together
"[..] can be used for a slight increase of wifi output with one router"
which itself is a statement that doesn't make any sense in the first place
(how should you increase the _output_ of your _router_ by adding something to
your laptop?) so i was trying to guess what you were talking about;
you should refrain from participating here if you can't express yourself and
resort to insults because of that.
I learned by now that you're a troll and i won't reply to any of your posts
anymore; please be aware that other members will do the same if you don't
change your attitude;
