here is the lowdown on wireless security...

Unsecured wifi can be used by anyone.
WEP can be broken in under 5 minutes at 128 bit
Mac address does not help as any sniffer can see the mac address in plain
text and spoof it.
Apparently WPA can have a packet forgery attack used against it and the
WPA spec says the access point must shutdown for
60 seconds when they detect this, making a very simple DoS attack against
WPA-encrypted networks.
I'm sure there are already tools out there that automate the process.
Certainly WEP and MAC address = open channel and you can expect to have
your broadband quota drained fairly quickly.

distance is no object. I have in the shed a 24 DBi antenna with an
effective range of several 10's of km LoS...

WPA2 is encryption + authentication and is to date secure.
the thing is I don't really know how to set it up so I can't tell if it's
broken or if I'm just incompetent. :-)

candidates I've considered

firewall problem
NAT problem
Windows sucking (WinXP SP2)
