Its not even supplemental, lol.Natoma said:MAC filtering would be crappy by itself. Stacked on top of WPA, or AES if you have one of the newer routers/cards, it's just another level of protection.
WEP is crap because it's your first line of defense encryption wise, and it can be hacked within minutes. MAC filtering was never designed to be your first line of defense. Merely a supplemental.
If anyone can crack your WPA or WEP, MAC filtering is not going to do SHIT.
It is the same level of protection as not broadcasting the SSID or turning of DHCP - in other words, almost none.
WPA is good pretection.
WEP is poor protection
MAC filtering, DHCP off, and no SSID broadcast is a mere annoyance. More work for you, and no real extra effort for a hacker. Waste of time.
