    Sorry to post this - I'm sure it's been dealt with before. How do I find the machine access code (MAC) number on my computers and set a WiFi network to accept only these MAC numbers?

    Setting up the MAC address filter will depend on your specific wireless router. I can give you some info on setting up a LinkSys router if you want, but other than that you should refer to the documentation provided with the router or on the companies website.

    As for finding the MAC address for each machine, you should do this. I will assume you're using some flavor of 10.3, if not, 10.2 is similar but not exactly the same.

    Open System Preferences (Applications->Utilities->System Preferences).
    Click on the Network globe under the Internet & Network section.
    This should bring up a listing of your available connections, double click Airport.
    You will then be able to see your Airport ID, which is your Airport card's MAC address.

    You would then setup your MAC address filter on your router to only allow your machines MAC's and you should be set.

    Let me know if this isn't clear or if you need any more info.

    If you happen to use a D.Link wireless access point / wired router, you need to enter both your wired and wireless computers' MAC addresses.

    On Linksys the MAC filter is only for wireless computers.

    I suppose D.Link figures someone who can physically plug into your network can't necessarily be trusted. That probably makes sense for an office setting but for the home the Linksys approach is fine.

    I use a Linksys WRT54g.
