This seems like a super basic question, but I've done a whole bunch of searching and haven't found anything even close to an answer.
I've noticed that whenever I have a youtube video buffering, the performance of online games severely suffers. As in, my ping jumps from 50ms to 500ms.
I've read extensively about QoS and how it can be used to re-prioritize the traffic. However, some routers do not support this, and even if they do, it's not very straightforward to configure at the very least.
I have a Motorola Surfboard, and AFAICT I can't configure QoS to prioritize the traffic to prioritize games over streaming video.
In lieu of that, is it possible for me to do implement something similar at the level of just my desktop? I have a feeling that for complicated reasons, it isn't. But I would like to know why.
