Basically, I have the netduma R3 and my ping has recently gone under a lot of spikes. I used to score an A+ on waveform buffer-bloat test, now I'm struggling to even get a C+ (a lot of the time it tends to be an F). I've used the ping optimizer multiple times, tried different congestion controls and it seems to not do anything, it states my ping is stable yet doesn't improve it, last test I ran I had an upload ping of around 400ms and my download would be at 6.9 (which I will take). So it obviously came to my conclusion somethings wrong with the upload.
I've done a lot of looking and honestly am super demotivated. The image attached is a score of what I got when I had the R3 the day I got it after running it's ping optimizer (which was August 2024), and this random ping spike / stutter / increase at times only recently started to happen.
So I'm on my knees here.
The images I've attached show an A+ result of bufferbloat when I had got my R3 back in August 2024, and the F result is today. I've also attached my speed test (I know, I live in London in a bad area where my speeds aren't good). The last image shows my conversation with Fraser, it was only the beginning so there wasn't much depth that we got into solving my issue. So here I am opening up a topic so I can get the help I need.
