What devices are using those MAC addresses? Your own PCs or something else?

You can see your own device MAC addresses, on windows, using 'ipconfig /all'
from the cmd line. Look for the line labelled 'Physical Address'. If
you're on a linux or Macintosh you could use 'ifconfig' and look for
'HWaddr'. For other stuff like printers and such you may have to look on
their labels to find the address (presuming they're networkable, of course!)

If it's not a MAC address of one of your own devices than it's something
else trying to get connected. There's not much you can do to "stop" them
from trying. But if you're got your WPA setup then they just won't make the
connection.

But if you're really concerned about being 'secure' then using wireless
isn't the way to get it. Sure, it can be made pretty resistant to casual
attempts, and WPA is currently as good as it's going to get for fending off
unwanted connections. But it wouldn't prevent someone from staging denial
of service or other attacks bent on slowing the network down so much as to
become useless. For that you ought to be using an actual wired connection.

So it all depends on just how 'secure' your situation requires.
