Feature request: WiFi timers

Having searched high and low for a solution, I don't think it's currently an option to schedule WiFi to turn off and on, such as in the evening. I'm interested in toning down exposure to radiation in light of documented health effects (e.g., hormonal and fertility concerns, among others). I'd also like to encourage myself to disconnect from constantly being online. I'm aware that profiles allow devices to be disconnected, but that's not a solution to my concerns. While I can just plug the router into an external timer, I'd appreciate a more elegant solution that won't potentially cause trouble with my router...
