A friend has recently asked me for a solution that would disable the wireless interface on his SOHO router during the night. Two simple EEM applets later we had it working; I've also added a third applet to ensure the interface does not remain disabled after a router reload.
You can find the EEM applet code in the CT3 wiki.
