Netgear R7400 QOS Issues

Hey everyone. I’m pretty new at this networking stuff, but hoping someone can help me out.

I have been using an ISP provided modem/router for a couple years with a DSL connection. I am supposed to be getting 30mbps, but all my recent tests are showing 10-15mbps. Here’s my issue:

The devices we mainly use are my gaming pc, connected via Ethernet to a Netgear switch then to the modem/router, and an Apple TV 4K (for streaming) also connected to the same switch via Ethernet. The issue over the past year has been latency issues, packet loss and lag while I am gaming online while my wife is simultaneously streaming YouTube tv via the Apple TV. There is no lag or latency issues if there is no streaming. Also, obviously, if someone sends a picture/video message on their phone via WiFi while I am online gaming it creates major lag and gaming interruption.

I decided to finally solve this issue by purchasing my own router on Black Friday, one with QOS so that I could manually manage and prioritize connections. I grabbed a Netgear R7400 from Best Buy for a good deal, finally got it set up and working with the modem, set up a QOS rule (the only rule) to have the PC set as the highest device, but it has made no difference. Packet loss, high ping, and lag is still there while simultaneous streaming is happening.

Am I doing something wrong? Did I buy the wrong router, or not a good enough router for my purpose? Any other insight of how to solve my issue? Switching internet providers is not a viable solution. I live in Alaska where I pay $90/mo for my advertised as 30mbps unlimited data connection. The other company’s unlimited plan is $180/mo and I am not paying that.

Please help if you can, thanks.

First, you don't say how the Apple TV is being viewed, is it streaming in SD,HD or 4K ???
If you are only getting 10-15mbps then you will have trouble streaming 4K.

Have you tried plugging the PC into the router directly ?

Try setting up QOS by service rather than device. (hopefully it will offer a list and you game will be on it.)

In data networking, all links are finite resources, and the more competition (it's anything but "fair") there is for use of a link, the more you start to get conflicts. It's just like the traffic on a road - the busier is it, then the more congestion you get which then effects any particular vehicle. When it's less busy, everything shuffles along together without much hassle.

QOS in your router is not necessarily the silver bullet to "fix" this as the router is not controlling any of the things upstream of it that could be causing the congestion. It's rather like standing at the end of your road and trying to fix a congestion problem by waving your arms and trying to persuade traffic at the far end to not enter the road until you are ready for them. Unfortunately, if traffic ignores your hand signals and still enters the road anyway, you still get he congestion.

QOS really only "works" if it's implemented from end-to-end (which is never going to happen on the Internet for technical reasons) or at source, such as the throttling sites like youtube etc. do to meter out their bandwidth their end.

QOS in your router works by throttling the requests from each of your local hosts to "send me the next lump of data" to give priority to one class of traffic over another or one or more hosts over the others. It can have some effect, but it's far from being a robust solution. Even in some of the best enterprise scale kit costing thousands of pounds, it is something of a black art.
