Game priority over Netflix streaming

[#1]

Is there a way to prioritise network traffic for my game instead of netflix streaming? Whenever I'm on counterstrike my girlfriend streams netflix and my ping spikes from 10-20 all the way to 100+ and it becomes unplayable. I don't want to make her have to stop streaming whenever I'm playing games. It happens on netflix but not youtube, that only goes to like 30 and it's more playable.

Can I not access QoS priority to throttle the traffic to netflix and prioritise my PC?

If it helps, my PC is on a wired connection while she is on wifi either from the TV or from her laptop

Hi @aniboi,
My experience on FTTC and FTTP is that applying QoS to the only upstream prevents the ping spiking when others are streaming.
I do not have to priortise one device above another or apppy QoS to tne downstream.
I am not a yamer but use QoS to make sure Teams and like work smoothly when working from home.
To implement QoS I use my own router running OpenWRT.
I do not use the Plusnet supplied router. It is in the cupboard as an spare in case my main router fails.

There is no QoS setting capability on the Hub 2. There is nothing to stop you buying a third party combined modem/router (I assume that you are on FTTC). The settings are here: https://www.plus.net/help/broadband/broadband-connection-settings/
