Something has changed with BT Infinity FTTC. High Ping spikes when streaming video

I cannot say for certain when this change took place. Sometime towards Christmas last year. First noticed when the gf was watching netflix and I would try playing some online games, that they were almost unplayable. Huge lag spikes. Dota 2 shows some live network stats and I could see my ping go from 30-40 > 250-400 every couple of seconds. 

I've been tearing my hair out trying to resolve this and had BT check out line. last month. Now the BT Engineer said he found a fault at the cabinet and this has been cleared by I can still see the same issues whenever video stream is being played. 

 

In fact if I load up Twitch now on my PC (hard-wired) and do a simple ping test, I can show you what I mean. 

These 2 tests, were taken 1 minute apart. Just simply twitch stream on and twitch stream off.

What the hell is going on? What has changed with the BT connection to cause this?

Re: Latency Issue- Ping Jitter While Gaming

Just another 2 months or so and then I can leave my contract. Look at the state of this connection. 

pinging google with a single twitch stream open on a roughly 50Mbps connection. I changed the interval to 0.5 seconds about a minute into the test and then you can see the instant I close the stream. Absolutely horrific connection! 

This connection is not fit for purpose. I hope the Ombudsman hammers them with a fine if this gets investigated properly.

For comparison. I just played 1 round of pubg but with no stream on.

Re: Latency Issue- Ping Jitter While Gaming

Hi @CAI_007,

Welcome back to the community, thanks for posting.

Sorry that you've been having problems with your connection when gaming and running a steam at the same time.

Would you be able to send me in your account details so that we can look into this issue for you?

I've sent you a Private Message with details on how you can get in contact with the mod team.

Thanks

Matt

Hi @CAI_007,

It looks like the fault has been fixed by the broadband engineer who visited the property. 

Can you confirm if you are still experiencing Ping spikes?

Matt

Re: Something has changed with BT Infinity FTTC. High Ping spikes when streaming video

Just posting what I messaged Matt in PM. The issue with ping spikes is not fixed.

 

Wanted to leave it a few days so that the line would be settled. Engineer said the line is in perfect condition. He could see their was a fault for 4-5 days in the middle of August which is why the connection speed was lowered by 50%, in order to stablise it. He could not say what had caused the fault. The equipment outside is not that old, relatively new housing estate. Plus i'm about 60 second walk away from the telephone exchange. Anyway, he increased the line back to it's full potential and run speed tests. Was showing 70mbps down and 18 mbps up. 

 

This is ping plotter from a single netflix stream running in the background this evening. As you can see, jitter on the connection, ping spikes etc.

Re: Something has changed with BT Infinity FTTC. High Ping spikes when streaming video

So it looks like Matt has managed to get my connection going through a slightly different route through the BT network. 

This is a new traceroute below, while the GF is watching netflix. I also played a full match of Dota while she was streaming.

5 less hops too. Much more stable connection:

Glad to hear that the connection is looking more stable now. 

Are you happy that this fault is now resolved or would you like to leave the case open and test the connection again in a week or so?

Matt
