I have a Cisco ASA 5505 as my home router due to work vpn connections. I am wanting to limit my step-son and nephew YouTube and streaming services on their cell phones and game consoles mainly. My step-son watches YouTube 10 - 20 hrs a day on his phone and i have found him sleeping with YouTube playing on his phone in the middle of the night.
I have already limited his data usage on the phone but with our home WiFi he is able to by pass it. I don't want to block it completely just limit how much time he uses it or maybe QoS on the ASA to limit the bandwidth. But if i do that, it does it to all devices so, when my wife wants to watch Netflix it would limit her as well so I don't think it would be a good option.
I have spare pc's that I could build a linux or windows box but I have no idea what software would work for this?
Any help or pointers would be greatly appreciated.
