How to view nearby signals on computer?

[Martin]

I have a wireless router installed on my home network for the benefit of a
few specific visitors who bring along their laptops. Only they are
authorized to connect. But we've noticed that the laptops from time to
time show other non-connecting signals apparently nearby. Is there any way
that I can see a similar display on my master desktop? Or do I have to have
a transceiver card like the laptops use and appropriate software?

Martin,

If you want to monitor wireless activity, and / or wireless connection attempts,
on your LAN, you either have to be able to query the activity of your router
from your computer, or you have to have a computer with wireless capability.
This requires either installing a wireless card on your master desktop, or
having your master desktop be fed information by another computer (or the
router).

Why, you want to hack into someone else's network? The cheapest way is to
install a "wireless" card into your desktop, the most expensive is to buy
the same tools most administrator's of wireless networks use.

NetStumbler. It only works on _some_ WiFi cards.
