I have an AirPort Extreme, we have 3 kids 6, 8, and 10. All our computers are in general space, and we manage their viewing content. 2 weeks ago we started hosting a 15 year old boy from Spain as foreign exchange student, he will be here 10 months and graduate 10th grade from our High school. Our "teenager in training". He's a really great kid, loves sports, is social, etc. Trouble is he has a iPod Touch he uses all the time for texting/facebook/etc. I'm ok with all that, what I'd like to do is simply turn off WiFi 11pm - 6am, automatically. His "downtime", sleep, etc. Can that be done with existing Apple software I have Mac OS X 10.7.4?
