Inconsistent Latency

[eggsmell]

Hello, I'm fully aware this could be a problem solely with my ISP's routing, but I'm interested to see if this is a known issue.

I got my Netduma R3 a couple of days ago, and left it on 4.0.21 for the first day. I did a bufferbloat test, and got the results below.

 

Still much better than my old router, (cut the download/upload active MS in half) so I didn't think anything of it until I did some searching the following day and found the 4.0.23 update.

After the update, I did more bufferbloat tests and saw the results drastically different.

As shown, the tests were consistently 27-30ms unloaded, between +3-10ms with download active and +1-5ms with upload active.
I live in New England, and with this update my ping to New York servers (speed tests, gaming, etc.) went from 45-50ms to 30-35ms. I thought it was great, and a more accurate ping for where I live. (~300 miles away.)

I played all night with the lower ping, consistent on any New York area server I connected to, and on any speed tests I tried. When I woke up this morning, I went to check the ping heatmap - only to find my ping to New York was back up in the 45-50 range. Speedtest pings are now also back up by ~10ms. I came back to the forums, and found the 4.0.41 update, hoping that might give me back the lower ping I had last night after updating to 4.0.23, but it actually stayed the same and just made my bufferbloat much, much worse.

Now on 4.0.41, I have the same high ping as 4.0.21, but my bufferbloat is significantly worse. The latency under load is consistently +60-150 for both download and upload. 

I'm going to attempt to downgrade to 4.0.23 to see if it fixes the bufferbloat and hopefully lowers my ping again, will report back soon.

After downgrading back to 4.0.23, the bufferbloat noticeably improved from 4.0.41 but is still very bad. Not sure why, but the upload active latency is consistently down to around +10ms yet download active latency barely changed.

@eggsmellif you go into ping optimiser have you unticked the box to disable on speeds test? You can also put your QOS setting on to always on when detected which does improve it.

 

i don’t use wave forum I use speedtest.net much more reliable I found wave forum jitter and latency is always all over the place and never reliable.

I do have the speed test disable box unticked, yea. Good call on the 'always on' setting, that seemed to have fixed my bufferbloat. Seems like I must have had something open in the background during my previous tests that was causing the router to use congestion control while I was running them.

Will update to 4.0.41 again later to confirm that fully fixed the problem.

Now if only I could figure out why my ping was 10ms lower the night after I went from 4.0.21 -> 4.0.23 and if it's possible to get that low ping back.

the best bufferbloat results for me have been with the 4.0.170 early access firmware. I get A+ results now. With 4.0.23, i would never even get an A. I have a feeling it is going to be different results for everyone because of their ISP and where they live with each different firmware.

Currently waiting to be given access to the Early Access part of the forums but will definitely give it a try once I can, thanks for the recommendation.

@eggsmellGlad the always on fixed the issue and should be fine on .041 happy gaming and may you dominate em

Great results with 4.0.41, although it might be slightly better than usual since it's late at night.
