How to tell who is trying to log onto my Apple Airport Express?

[JWSandi]

Are their any tools/app/programs I can d/l and run that will tell me if anyone is trying to log onto my airport express wireless?

I have it password protected and such, but I want to know if there is someway I can see if anyone has attempted an unauthorized log-in.

What makes you think that someone is trying to log into your Airport Express?

Look at your router logs to see a list of allocated I.P addresses?

Failing that, why not enable MAC Address filtering, so only devices with pre approved MAC addresses are allowed access?
