XR500 QOS speed issues

I disabled QOS a few months ago when I switched from PS5 to PC because of having speed issues with QOS when using my PC.  I thought I would try it again today and they are still there.  I've been using firmware V2.3.2.134-dumaos33-rc10 for months now.

Some information you might need is that I have a Nighthawk CM1200 modem, and Comcast is my ISP.  I've inputted 900 down and 40 up as my speeds.  When I let it auto-detect, I get 390 - 410 down and 38 - 41 up.

I use speedtest.net and internet test speed for the results.  Download is usually close but upload is usually about 50% lower on internet test speed than speedtest.net

With QOS disabled I get 930 - 960 down and 39 - 41 up

Using manual 900 down and 40 up.  I tried always, auto-enable, and never with both sliders at 100% I get 70 - 80 down and 3 - 4 up.  I changed both sliders to 50% but I got the same result as previously mentioned.

Auto-detected currently gave me 408 down and 39 up.  I tried always, auto-enable, and never with both sliders at 100% I get 30 - 40 down and 3 - 4 up.  I changed both sliders to 50% but I got the same result as previously mentioned.

I tried auto-setup with the same results posted above.

I have not changed any settings since switching from PS5 to PC except I removed my PS5 from the geo-filter and added my PC.

Can you please assist?
