Oh, hell yes, Brother-man!  This is looking good. Can you then block that
mac?

Yes, and there's more.  

If you have a subscriber re-distributing the service through a Wi-Fi AP
(such as an apartment manager offering free Internet to the renters from
your service), you can get a lot of information to help you discover it.
For example, NetStumbler (if you do a truckroll to the suspect with a
laptop running it) will reveal the MAC address of the AP no matter what
encryption they are using (it's necessarily revealed during the initial
association).  If it's attached to your modem and it gets it's address
from your DHCP server, then the MAC address of the CPE is revealed in
Option 82.  A quick LeaseQuery and BINGO!

Okay, I see the option 82......  I'm totally new to this one.  How do you
log the info from it?

This has DHCP option 82 written all over it. It's very popular in a DOCSIS
environment. I assume the Alvarion equipment doesn't support option 82. If
this is the case you could do it via an option 82 capable switch. The
switch could tell you what port, MAC, IP, etc.

Good luck.
