If you are using commercial access points they usually are designed to run from a central controller. You can push patches, filter policies whatever. I assume since you are asking you have consumer grade equipment and so you either write you own controller script or you do it manually.
Mac address filtering is a joke, it will take you more time to configure than it does to bypass.
You want to use WPA with certificates if possible. WPA with preshared key is ok but it does not take long for the key to get around in public environment. It is also possible to use a radius/ad server with WPA rather than using certificates.
I am a Compute Tech for a school and we are about toi switch policies of internet security to Mac Adress filtering. I was wondering if there is any way to push Mac Adresses to the Mac Address Filtering on all 9 wireless routers throughout the school instead of me individually adding each Mac Address on each Wireless Router?
