Higher Resting Latency and Jittering

Spammy2 — Wed, 13 Dec 2023 20:21:34 GMT

Quick Note:

- My PC is the ONLY device currently and ever on this broadband / installation of WIFI.

- It is connected directly to the hub via ethernet cable which is connected directly to the master socket.

- Speeds are fine, just the latency and ping.

-I have been through basic support and they have said my lines / local area is having 0 issues.

- I believe the PingPlotter proves the jittering and higher latency lies at the ISP server suggested by where the higher latency hops occur as Hop1 and the last hop have no issues (My end and the DNS being google)

Since the latest firmware update on Mon Dec 11,19:31:49, 2023 I have noticed an increase in my resting latency after around 5-10mins after I restart the hub. Originally and for the past 13months my resting latency was 7ms but now it lies between 10-13ms with jittering and causing me unable to play games competitively.

(Image 1) I'm not showing hops 1-3 but they were completely fine as I checked, but you can see this sudden increase in latency over this 10second interval graph

(Image 2) shows the same thing occurring the next day after I restarted the hub again in a 5 second interval.

(More noise and line attenuation details here)

My thoughts are it is the ISP server my router is bouncing off as I've seen it be slough . ukcore and redbus . ukcore I'm not sure if this switching is normal for traceroutes so that probably is normal.

Can anyone confirm or deny whether it is the ISP servers issue and how to resolve this problem and get back to a stable 7ms latency please !!

Does 5 or 6 ms make that much difference? If memory serves, that's about a 1/50 of human reaction times any way.

The difference in latency probably isn't the problem, I find the fact it jumps up to that consistently after I restart the hub when it used to always sit at 6-7ms. When it's always been that low its bizarre it now sits higher and is causing jittering issues

So, if I've understood your screenshot correctly, the jitter is less than 1ms? My original question stands. Does it really make that much difference?

I'll fetch some better screenshots as they were to demonstrate the jump in latency where as now testing in game (CS2) I am missing packets and latency is fluctuating. Just tried fortnite too and ping is fluctuating.

To answer your question Yes, assumed being wired directly for over a year having no issues playing the game to a high level I can immediately tell when something is off either being shots missed or slight change in movement etc... noticing this change when pinging regular DNS'.

Fair enough. I’m not a gamer myself, so I wouldn’t know but I found it difficult to believe such a small time interval makes any real difference. No offence meant.

No worries none taken, the ms response in CMD doesn't reflect 1 to 1 with in-game latency / ping as that's mostly be 30+ unless the server is in the UK it'll be around 20ms.

It's when pinging a server such as google, and the return time increases after 10mins of hub restart from what it used to be, to this new resting latency which also has introduced more practical jittering than shows in the images, it's just odd to me.

Again, I'm almost certain this began after this firmware update on Monday and believe it's out of my control, but willing to pay for an engineer to come and check the lines and for any disturbance that's all 🙂

Interesting you mention the firmware update. I see it's an incremental update on v41. That in itself suggests they've had a problem with v41.

Yeah that's what I'm thinking and I have competitive matches with time stamps and when I could tell night and day when something was off, matches the19:30 timestamp of this firmware update I was unaware was even happening

So it turns out since the night I noticed something was off (11th December) they filed a fault report for my broadband line that night and a scheduled engineer appointment for 21st December.

So from multiple calls, live chats and communications with them they have not seen this problem with all their testing and told me?

Instead... they sent a new hub to me today and I installed it and downloaded a game. After this I broadband tested through the BT website and that's where I was told there is a problem outside my control lol.

Fingers crossed they can fix the issue and thankyou for replying in the first place much love ❤️

I’ve had the exact same issue. Since the update my gameplay has been unplayable.
The download speed 75 and upload speed 19 are good, ping is good 15/20, packet loss 0 but I noticed high jitter on upload (100+).
I’ve tried everything

Hi @Hazza2107 if you are still having problems then you'd probably be better off starting a new thread detailing exactly the problem you are seeing and how you are seeing it.
What type of connection do you have?
What game is the issue appearing in - and how does it manifest?
Are you using WiFi or a wired connection?
How are you measuring the latency (as overzealous measuring can itself cause problems)?

Just had an engineer out this morning, explained to me that he's almost certain it isn't a physical issue for me after changing filters, cabling and testing my line which came back all good. He was quite as baffled as to me on what this problem could be. It was slightly out of his job role as Openreach don't deal with latency he said. However, he as much help in assuring me it isn't a physical problem.

The only tests I have remaining are christmas tree lights around my house or that firmware update I mentioned I received on my hub the same evening I felt this occur. So I suppose I wait for the next firmware update or it's the christmas tree lights LOL as that's the only thing that was changed physically around my house near when this happened 🙂

Your problem sounds similar to mine man, it's not so obvious it rings alarm bells but it sure is a problem when gaming competitively. I hope we find the fix lol but yeah make sure you try all possibilities that it could be physically such as a new hub and cabling etc... just in case your issue isn't the same as mine is all I can suggest 🙂
