5 persons with each their PC/Phone/Tablet besides that also Media Player, TV, Setupbox, BluRay, printer, XBox. All mostly working without any problem.
But my son and daughter found out how to download music and film and play games which use an enourmous bandwidth.

So what I'd like to do is set a specific MINIMUM bandwidth for the computers in our house. This just for the PC's. So seprated by IP or better by MAC.
My idea is to set each PC/Laptop (no other devices) to a minimum of i.e. 5 Mbps. And what's left over can be used in common.
is this possible and if so... how can this be done?
