DinoDaDog Posted Monday at 08:42 AM Share Posted Monday at 08:42 AM 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.

Administrators Netduma Fraser Posted Monday at 02:07 PM Administrators Share Posted Monday at 02:07 PM 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 Link to comment Share on other sites More sharing options...
DinoDaDog Posted yesterday at 02:32 AM Author Share Posted yesterday at 02:32 AM 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. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted yesterday at 02:10 PM Administrators Share Posted yesterday at 02:10 PM 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. Link to comment Share on other sites More sharing options...
DinoDaDog Posted 18 hours ago Author Share Posted 18 hours ago 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 Link to comment Share on other sites More sharing options...
