Hello, sorry for my poor English.
I recently encountered a problem. There are now several people connected to my wi-fi. They are very actively using it. Is there a way to control their traffic speed?
My internet download speed is about : 224.54 Mbps
I have a D-link Model Name: DIR-882. Hardware Version: A1. Firmware Version: 1.11.
Firmware Externel Version V1.11
Firmware Internal Version: V1.11B01
Date: 2018-07-03 20:10:01
I enjoy playing video games and because of them downloading stuff, my internet connection is really slow at times. I would like them being able to use wi-fi but also I would like to get a piece of that cake

It started on the day they connected to the wi-fi, so I don't think it's a provider problem.
Open to any suggestions. Thanks you!
P.S. first time here, down know if same question has ever been asked before therefore I am truly sorry if it was.
Cheers,
