We have a number of WiFi devices (laptops, cellphones and some iThis and iThat) at home. I want to monitor which device, when, the length of time spent and the sites visited everyday by my children. A log at the end of the day is fine as long as it is in human readable form. I am less concerned with the content that they access than with when and for how long. All devices access the internet through a Linksys E4200 router. I have named all devices using the Linksys software (on the windows side of my dual boot). I may be missing a trick, but the router appears NOT to have the capability that I am seeking. I block WiFi access when I need to but that is not the best solution for me.
Any suggestions? Any readily available tools or something that I can hack together as long as it is simple.
