I can't find a way to turn the wifi off at certain times using parental controls. I have set a custom filter for sites I don't want access to but would like to set times where there is no wifi access at all. Under parental controls timings you can remove the filter at certain times and set homework time (where there is no social networking) but you can not do this overnight (it complains that the start time is before the end time) and you can not set differences for week days and weekends. Please help...it is driving me crazy. Thanks!
