Mach3r Posted August 29 Share Posted August 29 I can’t get this bufferbloat under control for the life of me with this router. I keep tweaking the congestion and it doesn’t seem to get any better. Is there a setting that might help? Link to comment Share on other sites More sharing options...
iOrcus Posted August 29 Share Posted August 29 what helps me the most is by capping my bandwidth iniside the R3. for an example i have 1gb fiber and look how i capped my speed below for the BEST bufferbloat and the LOWEST jitter possible. the congestion controll % i always use is between 70% 65% 50%. @Mach3r Link to comment Share on other sites More sharing options...
iOrcus Posted August 29 Share Posted August 29 this is how it looks like with no tweaks Link to comment Share on other sites More sharing options...

Administrators Netduma Fraser Posted August 29 Administrators Share Posted August 29 What is the model of the modem/router the R3 is connected to and how have you set that to ensure all traffic flows to the R3? E.g. R3 in its DMZ, modem/bridge mode. Are ALL devices connected to the router? Link to comment Share on other sites More sharing options...

The modem is an Arris surfboard SB8200. I have to be honest I am ignorant with DMZ, bridge mode. But I did set my devices up in priorities.

Administrators Netduma Fraser Posted August 29 Administrators Share Posted August 29 Thanks! No worries, so if you access the Arris interface, can you find an option for DMZ? This could be in WAN Settings or Security potentially, if you find it, copy the WAN IP from the R3 WAN page and then paste that into the DMZ on the Arris. Make sure all devices are connected to the R3 then try the tests again. Link to comment Share on other sites More sharing options...

I am not having any luck getting to an Arris interface that allows you to change settings Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 30 Administrators Share Posted August 30 Looks like it can't be access but I'm sure I saw that it provides WiFi, is that correct? Link to comment Share on other sites More sharing options...

They said there is not a DMZ setting that I can change on a cable modem. They said that is a router setting. Link to comment Share on other sites More sharing options...

If not that makes sense, if it does that is quite confusing. Assuming it is just a pure modem, I'd suggest testing with downloads while following: https://bit.ly/bufferbloat-test start with a high value e.g 95%, test, decrease 10%, test, decrease 10% etc, until you get to a value that is pretty good, then try 5% either side of that value to see if it can be improved. Important to note that Download/Upload on CC don't have to be the same value & you may have a better experience with differing values. This is more of a real world test as you're actually doing traffic you would normally do. Link to comment Share on other sites More sharing options...

The best I have ever seen is like 20ms on download and it fluctuates back up. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 30 Administrators Share Posted August 30 Is that using PingPlotter or just the waveform test? Link to comment Share on other sites More sharing options...

Administrators Netduma Fraser Posted August 30 Administrators Share Posted August 30 Do PingPlotter as described above as it'll be a better test Link to comment Share on other sites More sharing options...
