Auto ping Host & In game ping differ by 30/40ms

[Piplowe]

When playing a game of Warzone the auto ping host feature normally states between 8-16ms yet the in game monitor states 40-50ms 

That can't be right though, I know the playstation is another hop from the router but an additional 30ms when the playstation on a wired connection seems odd.

Using an XR300

Warzone normally reads higher due to processing. Multiplayer is a bit closer but usually 16ms over what you read on DumaOS.

Hey, welcome to the forum!

As above! The ping the Geo-Filter shows is the one you can influence and so if that's as low as possible then you've done everything to get the best connection possible.

[Piplowe]

Thank you,

It's so frustrating,

I had Plusnet assign a static IP address and the game played perfect for two days.Then it went back to the same poor hit detection / aim assist, shoot first die first and frame rate drops. 

So I'm assuming it's a ISP issue.  

[Netduma Fraser]

It could also be server side issues so try forcing servers slightly further away and see if they play any better.

[Piplowe]

I've tried with forcing a few locations without much luck. Italy worked a few times the auto ping states around 30-40ms .
I know to change the locations before turning on the PS4. It's so intermittent and you can wait up to 5 mins just to get into a lobby. Worse results if I try and use US servers. 
The frame rate drops when I'm close to other players and people seem to teleport. 

Am I right in assuming it's all UDP traffic for Call of duty? 
 

 

[Netduma Fraser]

Are you using QoS/Traffic Prioritization at all? Yes pretty much.

[Piplowe]

Yeah QOS is set

[Piplowe]

Can The ISP or Game detect packet loss if it's UDP ??   
Is there a way to test ?  

Everything seems fine until you run into other players and then the frame rate goes all over the place.  

[Netduma Fraser]

Okay you've got far too much being done to the console there. Disable DumaOS Classified Games as you're basically trying to prioritize it twice so that will conflict. You're using 3 different forms of getting the ports open. Remove the port forwarding and leave the DMZ & UPnP on. I wouldn't be surprised if it played better after that.

[Piplowe]

Will do, over time settings get tinkered out of frustration. 
Originally just put it in the DMZ, then added forwarding and turned off DMZ, added Specific prioritisation, turned off classified games. 

 

[Piplowe]

Hi Fraser, Just to confirm was that leave the DMZ as is or remove the PS4 from the DMZ on the XR300.  I'm assuming the latter. 
Also on the plusnet router what do you think is best?  UPnP enabled and XR300 in the DMZ ?

[Netduma Fraser]

Keep the DMZ enabled for the console on the XR300 but remove the port forwarding. On the Plusnet keep the XR300 in the DMZ, disable UPnP and the WiFi and connect ALL devices to the XR300.

[Piplowe]

Hi Fraser,

I tried above but no improvement in UK & European servers. 

I've been playing on the US servers (East coast) for that last couple of days, the games with pings above 100ms seem to more playable but still having issues. As I normally have to wait for 5/10 for a game of Plunder. 

Just seems like an ISP issue, 8ms connections to a host from the XR300 should be good enough to play in the UK servers without issue, unless it's lag comp gone wrong. 

I've attached a screen shot where the experience was really bad on a US Server,  firing first & no hit markers.  I was watching the send rate whilst moving and firing my weapon but it had no effect on the graph. 

Is there anything glaring from the graphs that may point to an issue. 

 

[Netduma Fraser]

Apart from the ping being higher and the server being in another country no it looks fine. Try forcing Germany or the Netherlands, I think their servers are generally pretty good.

[Piplowe]

Hey Fraser, I tried Germany which wasn't any better, then Italy which was worse.  
I noticed that on my previous screen shots from the US, I had host tick rate but not when I played games in Germany & Italy

Germany -  seemed like I was half a second behind the play.  

Italy - Milan dedicated server - Are the spike in send and receive rate a concern. 



I know this is probably ISP related, However,  I appreciate your help and the ability to troubleshoot with the netduma
I can see the antibuffer bloat working with a speedtest to fast.com  With a Ping of 9ms and additional 3ms when loaded. When it's off it jumps to 122ms loaded.  


Do you have any other suggestions?

 

[Netduma Fraser]

Your pings are pretty decent, that does look like the server is a bit unstable though. There are some French and Spanish servers that would be worth a try.

[Piplowe]

Hey Fraser, Tried above and not much difference. 


FYI - Open reach are investigating a line fault. 

It also looks like my upload has a Retransmission High setting.  Probably adding some Delay/error checking which affects the game.  
  

[Netduma Fraser]

Ahh hopefully they'll be able to fix that then, let us know how you get on after it is fixed.

[Piplowe]

Hey Fraser, the fault was fixed but the issue is not any better.  

I think this could be down to the Retransmission set to High and Error protection off on my profile. Shown on the GEA result above. 
There doesn't seem to be any issues with download it's the upload.  Which is probably causing the issue with the game. 

When I run wire shark captures from my laptop I see lots of 
TCP DUP ACK,
TCP ACKed unseen segment
TCP Spurious Retransmission
ICMP    Time-to-live exceeded   
TCP Retransmission

Other Error
Reassembly error, protocol TCP: New fragment overlaps old data (retransmission?)

I'm not sure if the netgear can do anything to mitigate above, if so please can you let me know. 

Thanks

Here are some example Wireshark captures if anyone wants to reference.

[Netduma Fraser]

Thanks for that information, some retransmission is expected just due to the nature of TCP but you are getting quite a lot. If you connect directly to the modem do you see this same behavior? Also would you be able to test with another PC?

[Piplowe]

Thanks Fraser,

I should have said the original captures where on my mac using the plusnet modem on a wireless connection. 

I've added 4 more wiresharks to the google drive link using another PC 

Two Wireless and Two wired

If the connection is having trouble with TCP whats the UDP like ? Obviously harder to diagnose UDP issues. 



 

[Netduma Fraser]

Ahh understood. It could be the modem perhaps, do you have the ability to swap that with something else? For UDP you'd probably need to have a game running at the same time you do the test.

You aren’t alone with this. I reckon it’s got to do with too many ports being open. I am with talk talk fttc and when I test the speed on the PS4 through fast.com I see latency unloaded 4ms loaded 15ms download 67mbps upload 0.7mbps and the again if I test with iPhone same result but upload speed measures 17mbps. So without the upload speed the ping will spike. I had the same issue with o2/BE unlimited adsl2 a decade ago.
