QoS (Enabling the Administrator to throttle or control bandwith of other users on the Network)
Community,
I have a young gamer in my home and he spends hours upon hours on his games.  He is currently connected to my network via my 5Ghz band.  He has 4 devices he can use at any given time.   I would like to be able to limit his bandwidth rather than "Blocking his devices" at a said time frame. 
 
 I have noticed recently a downgrade at certain times that my 940mbps speed on my 5Ghz band can go down to 200mbps for no reason that I can explain.
 
 I would like to be able to throttle his device speeds; limiting his game activity.  
Thanks.
