And, one kid is playing games online and the other is FaceTiming friends in a marathon call.
Have you asked, bribed or manacled your kids and others to cease web activity during the sound downturn times?
There is a much better solution than cajoling your kids. Look up Quality of Service (QoS) and how to set it on your router. This will enable you to allocate bandwidth to streaming that cannot be usurped by Call of Duty or FaceTime.
You don’t need to allocate a lot to streaming. Even a hi-res 192/24 stream only uses about 10 Mbs.
