a similar thing happened to me last weekend.  My wireless setup is a Win 98 
laptop + Orinoco card and a Debian Linux box + Orinoco card + cable 
modem.  It started when I was experimenting with DHCP.  I had an error in 
my DHCP config file on the Linux box so DHCP didn't start.  The card still 
got an IP address from somewhere.  After a little digging I discovered that 
there were a poorly setup access point nearby that I could connect to and 
"steal" Internet access.  until then I thought my neighbors were in the 
dark ages when it came to wireless networking so I was careless about 
wireless security.  Right now I am using WEP & iptables to control access.

If you are comfortable with Linux, I would suggest using that instead of a 
modem AP.  Use a small Linux system to share the Internet access and 
connect it to the AP with the wireless hosts.  It will give you more 
flexibility and it will make debugging easier when odd things happen.
