DinoDaDog Posted March 31 Posted March 31 Hi all I hope someone can help as this is driving me crazy. I have got a Telstra smart modem 3 on 250/25 mbs plan modem firmware 21.4.0500 DomaOS version 3.3.688 My modem test gets great under load upload and download ping tests but when i do a buffer bloat test from mc pc the download is good but upload is bad over 100. I tried a direct connection to my nbn modem and i dont get the high upload and get a A+ score but thru the modem not matter what i do to internet optimiser it stays above 100ms. I have played with upload and downlaod sliders from 70% up and down. Set my computer to a computer a playstation a game console. Added pc to priority traffic with all ports and set to default. On the odd occasion i think i get it and i get a A with very low upload latency but then i run the buffer test again and boom back to 100+ms. Again remove modem go direct to nbn modem and low upload latency ping. Not sure why the modem can test under 25ms down and up or its benchmark test but my pc cant get good upload ping.
DinoDaDog Posted March 31 Author Posted March 31 i did another test just now direct to nbn and the upload ping halved
Administrators Netduma Fraser Posted March 31 Administrators Posted March 31 It'll just be a case of fine tuning the percentage for upload - as your upload speed is a lot lower it is easier to saturate and for bufferbloat to occur so you may need to be more or less agressive with the percentage for it
DinoDaDog Posted April 1 Author Posted April 1 Yes I have tried the sliders starting at 70 going up and down by 5% and testing. Tried from 50% up to 100^ for upload and nothing seems to help.
Administrators Netduma Fraser Posted April 1 Administrators Posted April 1 I'd suggest following this guide https://support.netduma.com/en/support/solutions/articles/16000074717-how-to-test-your-internet-ping while downloading/streaming etc and start with a high value for Congestion Control (set to Always), say 95% then check, decrease by 10%, check, decrease by 10% etc, until you get to a value that is pretty good and then try 5% either side of that value to see if it can be improved. It's important to note that Download & Upload on Congestion Control don't have to be the same value and that you may have a better experience with differing values. This will be a more real world test.
DinoDaDog Posted April 2 Author Posted April 2 Yes have tried this and download can be great 4ms latency but upload stays at 100+. I start from 100% and have tested every 5% under it and it does not budge. Can this be a NBN issue
Administrators Netduma Fraser Posted April 3 Administrators Posted April 3 Are you using PPPoE/VLAN or IPv6 at all?

Administrators Netduma Fraser Posted April 4 Administrators Posted April 4 Are you actually experiencing any issues with the upload at all? It may just be due to being a slower upload the test reports high bufferbloat regardless
DinoDaDog Posted April 4 Author Posted April 4 No real upload issues. I just can’t figure out how to get it consistently lower. For some reason I can get random A scores with very lower bloat but mostly it sits over 100ms
Administrators Netduma Fraser Posted April 5 Administrators Posted April 5 If you're not encountering any issues with it then you're chasing numbers on a test that wouldn't translate into a better performance for you. However you have it set for upload now will be fine
