Hey
At the moment, I'm helping my school set up an AP for the sixth form common room (I'm part of the student council). What we are trying to achive is set up an AP which we can monitor easily, and work out who has paid their share to use the AP (we're organising it so you must give a donation in order to use the wireless Internet access... just so we can pay the ISP's bills).
In other words we want to make sure that unauthorised users cannot use the connection (isn't that the whole point of network security?).
I saw an article in .net mag a while ago involving AirSnare, or somthing like that, to prevent people from using an AP.
We don't have any gear yet, so all suggestions are welcome as to the sort of setup we should think about. We're getting an ADSL line installed, so I think its probably better value getting a router with modem, rather than a PC with modem and a wireless card with NAT running on it.
MAC filtering is certainly an option, as is WEP, but that would mean someone could spoof the MAC address of a legit user, or possibly use an ARP inject. Appart from anything, people might get new cards.
Sorry about the long-ness!
