Well I don't think it's such a bad idea because we have RouterBoard R52 cards and the people around here hardly know anything about computers as it is, plus we use WPA2, I'd just like to use WPA2 and MAC filtering both but I would like to do wildcards to make it easier on myself not having to login to a router each time someone does an installation. Just a pipe dream I guess.
Why bother with MAC if your network is not vulnerable? To be honest MAC filtering is not at all secure. If someone has the ability to crack you wpa then they will certainly bypass your MAC filter in no time
routing just a little bit of the world
