Is there any way to put an "On and Off" timer on a device to limit the internet usage? I've heard you can set it up somewhere so that you can set the times when it can be used. Any ideas?
You can do this on the Super Hub model that you have.
The Timed Access Rules can work either via assigned LAN IP or by device MAC. Access your Hub's Advanced Settings and select Security then either MAC Filtering or IP Filtering.
Give that a try and post on here if you have any questions. Don't forget to let us know how you get on
