Adriano, you're going about this the wrong way. There's this strange quirk in the human brain, which means that when people get a bit techie, they tend to lose whatever psychic powers they may at some time have had.

Therefore, when you ask them for help, you have to give them some idea of what you're talking about. ;-)

Now, I'd guess that you've got a wireless router, wireless connector(s) for your computer(s) and a broadband connection. Am I correct so far?

However much I rub my crystal ball (no insinuations, please!), though, I still can't pierce the veil any more than that.

You need to tell people:

What service (broadband? ISP? modem/settop box and what type?) you have

What router and connector(s) you've bought

And what computer(s) you're trying to connect: what make and model(s), what operating system and perhaps some description of the system.

Also, of course, whether the connection was previously set up (if it was...) with USB or ethernet.
