Hi all. I'm wondering if anyone knows of a software program that would allow me to control access by individual computers to our home Airport Extreme wireless network at the Airport level? I would like to be able to turn off access to the Airport connection after midnight and turn it back on in the morning. (I have teenagers that don't want to watch Hulu.com all night!). Is this possible? I would rather be able to control this at the Airport level than to use parental controls at each of the computers in the house. Thanks for any input.
