Constant Packet Loss On UDP Upload

EDIT: Forgot to mention my line syncs around 40/7 and I have QOS in place capping the connection at 39/6 using OpenWRT to fix buffer bloat. All other devices that connect to the net are switched off so only the PC is connected and as you can see I'm using low bandwidth limits for the tests so the router isn't loaded.

 

I've been monitoring this for about a year now since I first noticed it. Since about 2015 (was on BT Infinity back then) to present-day online gaming has felt really inconsistent like I'm always at a disadvantage due to some kind of delay/being out of sync with the server. It feels like packet loss but games always report 0% packet loss in their monitoring tools.

About a year ago though I did some UDP tests and found a constant small percentage of packet loss on the UDP upload with spikes up to 12+%. I get small pockets of time where I can run tests for a couple of minutes with 0% loss but other than that it's pretty much constant regardless of the time of day.

Here's an iperf3 showing various amounts of UDP packet loss at different upload speed.

And here's the results of a continuous UDP speed test.

Here's a couple of local runs of iperf3 showing it's not local hardware or software problem.

I'm currently on the G.Inp trials but that's only been for about 6 months. I noticed this packet loss about a year ago and I'm certain its been there for years before then even when I was with BT Infinity but never noticed it. Any help appreciated.

 

Cheers!

Re: Constant Packet Loss On UDP Upload

I've seen that having a static IP assigned to their connection has helped people with UDP packet loss in the past. Could this be helpful to me? I was just looking on my account page and cant configure a static IP even though I have been able to in the past. I have the message

Re: Constant Packet Loss On UDP Upload

Looks like I now have a static IP, can someone confirm this as I've had no notification of one being applied? my host is now reported as myusername.plus.com and after a couple of router reboots, I've kept the same IP. It hasn't fixed the upload loss though. What should UDP bandwidth be like? Is it lower than your actual connection speed or should it be the same? I can see the higher the UDP bandwidth usage the more sustained packet loss I get. At just 0.5Mbs I'm getting spikes up to almost 10% loss. For example, playing CS:GO network usage for csgo.exe is hitting 0.6Mbs so surely this is causing packet loss too even if the game isn't reporting it (the game reports average over time too, so it might always still show 0%  even though I am getting short spikes of packet loss). I don't want to report a fault just yet, id like some insight on this problem first. Im pasting some iperf3 logs below. Is this expected/normal? Why wouldn't games report packet loss even though I'm obviously getting it on the upload? Could it be routing? I know for a fact a BT engineer will do nothing about this, I've been having problems with gaming for years and had many BT engineers out but it was never fixed.

 

EDIT: I also have the pro addon so I'm guessing my UDP traffic for gaming should be prioritized.

EDIT 2: I have tested connected to the test socket, 2 modem/router setups, different network drivers and multiple rj11 and ethernet cables.

Re: Constant Packet Loss On UDP Upload

I'm also having the same issue with UDP upload loss 

Had 3 engineers out recently, twice for voice fault and one for bridge tap.   

Question #206150184 for internal plusnet reference. 

My connection is 70Mb/20Mb

Running 10 Streams for 3 second at 1Mb Bandwidth - upto 30% packet loss. 

iperf3 -c (my digital ocean server) -p 5004 -t 3 -P 10 -V -b 1M -u
