I have used timed access to limit my kids use of the internet. I encrypt my wireless network with WPA 2. However the setting no longer work, stopped a few months ago. I have reset my Airport extream, reentered the MACs, but I can no longer limit access to the network. What can I do? Both Mac and Windows computers are in use.

Are you limiting this with Parental Controls on the Mac? Or something your are doing on the Airport Extreme? What is happening that prevents you from setting this again? Error message? Grayed out options? All set OK, but just not working?
