Ping Spikes / Bufferbloat at an all time high.

[h_mmy]

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.

It's going to be difficult to get better results without ALL devices being connected to the R3, that's why you felt as though adjusting Congestion Control was barely doing anything because it's only applying to 1 device out of your entire network so that's all it can control. Devices connected to the hub can do whatever they like and the R3 can't do anything to stop them so I don't know how much you're actually going to be able to improve things without doing that.

Also are you purely concerned about the test results or are you having a negative experience in game that coincides with this? Put the R3 WAN IP in the Hub DMZ.

1. What are the speeds you pay for/receive? 
2. Have you entered those speeds into the router?
3. How have you setup Congestion Control?
4. How have you setup SmartBOOST?
5. What game are you playing?
6. What platform are you playing on and how is it connected, via ethernet or WiFi?
7. How have you setup the Geo-Filter?

1. The speeds I pay for/receive are 53-73Mbps with an upload of 14-18Mbps
2. I've entered the speed into the router, yes, however speaking with the BT technician OTP said speeds lower than my advertised.
3. From the first way I set up the congestion control was it was by clicking expert, letting the download and upload to stay at 100%, whilst also letting the congestion control mode to be on auto. I ran the test in ping optimiser at expert too.
4. SmartBOOST was enabled prior to me factory reseting my R3.
5. I've been playing Valorant and OW2. I had believed it was PC issues that were causing these ping spikes as every time I loaded into Valorant my ping had shown at 200ms. It had needed "time" to "calibrate" my ping back to normal (which was 12ms) however my ping was a lot lower compared to what it was (around 7ms). Playing the game I could tell I had immense stutters and ping spikes which to a point it had to tried to stabilise the ping by doubling my ping to around 14-20ms.
6. The platform is PC, the way I have my network setup is having the BT Smart Hub 2 connected to the R3 with the R3 included ethernet cable. So it would be ethernet goes into smart hub 2 LAN port and the other end into R3's WAN port.
7. Geo-Filter is disabled as the feature doesn't benefit me at all.

I've just now connected everything to the R3 completely, all devices. I've also added it to the DMZ.
