Any 'free' Wi-Fi' intrusion detectors? I think my neighbours free-riding!

[Paul]

I would rather not pay for one if I could get it free, but what I would like
is some kind of monitor that will tell me if someone other than those
invited come onto my network.
If there isn't any free, then what would you suggest if I have to buy one?

Thanks Guys
Paul

Use MAC filtering (supported by access point or wireless router) and MAC
addresses outside the permitted list can not connect.

Hi Paul,

Most routers have a log, and many can block by MAC address, so if you see
one listed that is not yours, use it to block the unwanted visitor. Also, a
wireless g router should have WPA available - use it.

If you setup your Wireless properly no-one would be getting access to
your network. Maybe, rather than looking for detection methods, you
should look at the zillions of articles on the web that detail how to
secure your wireless network.

Just what your neighbor thought.

Why bother? Just secure your network so no-one can get in without the
password. WPA should be available for free.

If you want to check, before you secure the AP, you can look at the
DCHP status table in your Linksys (or whatever) switch/AP. It will
show you the MAC addresses of all the machines that are using your
network.

On each of your PCs an "ipconfig /all" command will show that machine's
MAC. The MAC address(s) you can't idenfity are freeloaders.

3 bytes in the MAC address identify the manufacturer of the ethernet/WiFi
interface on the machine, which is help in identifying the culprit.

google "MAC address manufacturer" for a list of the manufacturers.

Then secure your AP.

Google for a program called "Airsnare". It's free and it does what you want.
