Meph, I can hardly believe you wrote this stuff after your post
"Public Access WIFI Security". And with an email like
"dont.worry@xxxxxxx" you have got to be joking. Unfortunately the OP
might take you seriously and we don't want that, do we?

Tardus_merula, MAC filtering is not a security measure. 

Think of it like this. There are baggage locks that shy away the
occasional temptation and there are kryptonite locks that resist New
York mobsters. WEP is so fragile today that it hardly offers
resistance against tampering. It is very easy to find tools that crack
WEP, they are publicly available on the internet. All that is needed
to break in is the will.

MAC filtering is even less than WEP. Even if you never turned on your
computer (which transmits your MAC) it is easy to silently try all the
possibilities until a match is found.

Don't listen to Meph. And from this point on, neither will I.

There is no way anything can be totally secure, the only thing security mesaures do is prolong the time until you have been compromised. If you have more than one security measure (ex. WPA2 and MAC address filtering) it will take longer to crack than if you only had one of them.

BTW i'm still new at wireless security, and even the entire security field in general, so you will have to cut me a little slack.
