I have WEP 128bit encrytpion (I know WPA is better but I have 2 DS's which don't support it). I'm also not broadcasting my SSID, and have an Access List set up to only allow MAC addresses I set to connect. Just wondering which of those 3 methods (encryption, not broadcasting SSID and MAC filtering) is most secure? Are all 3 necessary? And is there any performance decrease with any/all of them?
