Hi Paul,
How do you see the MAC-Address vs IP address ? Are you using separate your
wlan using vlan ?
There are many possiblities related with, depend on your wi-fi & wlan
setup. If your wlan rely on mac-address restriction, the attacker perhaps
try to spoof your legitimate mac-addr. Typically they will brute-forcing
your SSID, ... so on. Try to put Layer 2 analysis tool like
ethereal/tethereal at your wlan.
But if your see the mac-addr from switch layer 3 where AP configured as
different vlan, then it could be problem on how you see the mac-addr ):-
Cheers,
Arif Jatmoko

I was in a free wi-fi hotspot the other day and just for kicks ran an
NMAP scan to see how many people were logged on.
I noticed something peculiar though. Every IP address had identical MAC
addresses. Is this some security thing the hotspot had going on? Or is
it some kind of devious thing going on by one of the other customers in
the hotspot?
