Linksys Wireless Router :: E1200 Parental Control Device List?

I'm trying to limit my kids' access to the internet during the night, since I caught them plugging their laptops and the Xbox into the router's Ethernet ports late at night so they could circumvent the wireless guest access. The problem is, I only have 5 available control slots and the list of devices I browse to choose from is vague at best. Half of the devices listed in parental controls say "Network Device" and the other half say "iPhone" or "iPad". Isn't there an easy way to choose the correct devices to restrict, like by IP or MAC address? And if not, why is this so confusing and difficult? I have a family of 10 in my house and everyone is connecting with their own phn or 3 iPads, 2 laptops, 2 desktop PCs, 1 Xbox and 1 PS3.I tried limiting the DHCP Reservation list, but that seems to only affect the wireless access, not the 4 ethernet port connections.
