Hi, Ray...

Here's what I do. I go to the router config, turn off access control, connect,
and when I turn access control back on, the router suggests that I add the
correct MAC address to the config. No Windows or Mac required, although they
are just fine, too.

I don't get the point.  Normally I can see any router that is within range.  Whether I can access it depends on whether it is unlocked.  I cannot see the router and it cries about it.

Neil has a small built-in safeguard against a man-in-the-middle (MTM) attack. As MAC addresses can easily be forged, creating a generic whitelist of MAC addresses is weak security, at best. By going Neil's route, *all* clients are forbidden to attach until he disables the security. At that point, he lets the client connect, adds that single MAC to the whitelist, and away he goes. Unless someone is trying to access the network at that exact moment (with *his* MAC), he should be reasonable assured that he's the only one connected.
