VDSL UK High Latency

[Jack9127]

Hi there,

I haven't noticed any performance issues until recently. Lately I have noticed a latency increase with my broadband service at certain times. I've restarted my router and can confirm nothing else is causing the spikes, no big downloads, and like tonight just myself using it. I noticed this when playing online games and I normally see a 24ms ping time, and it prompted me to do some testing. I did various traceroutes and ping tests and they ranged between 56-98ms.

Sample traceroute tonight to BBC:

Tracing route to bbc.co.uk [151.101.0.81]
over a maximum of 30 hops:

1 2 ms 2 ms 2 ms vodafone.connect [192.168.1.1]

8 55 ms 56 ms 56 ms 149.11.166.202
9 64 ms 62 ms 62 ms 151.101.0.81

It looks to be this where there is some sort of congestion?

I'm posting an update here aimed at Vodafone, just to prove there is an issue with certain aspects of the Vodafone broadband network that needs to be taken seriously and fixed. I answered all the questions on this thread but I was not helped, nor was I on Live Chat. My high latency issue turned into very slow speeds, and since I left these have instantly gone. Please see the below of what it turned into on Vodafone, compared to what I get now with the new provider. 

*The same exact equipment - no changes within the household as stated even when I was still on Vodafone

*Screenshot of the Vodafone router showing healthy sync speeds with low SNR

*Speedtest of Vodafone even on a sync profile of 79912 downstream and 19999 upstream, get less than 1Mb and high latency.

*Screenshot of the new service on a lower speed package, but still get more than the 79Mb profile I was on Vodafone with. Also note the excellent standard latency.

I can see on the forum a few others are having issues and whilst some people are no doubt fine, the slow speed and latency was not just isolated to me. I would hope this is an insight that more needs to be done for users showing clear issues here, the service I got with Vodafone was an absolute disgrace and all my leg work trying to show this was disregarded. I written a complaint about this higher up the chain, you failed me as a customer where clear issues were present. I can only hope this does not happen to other users, your network needs fixing and someone needs to acknowledge this.

This is what I get on a 38mbps VDSL Vodafone connection:

Because you're not using host-212-158-250-32.dslgb.com as the host connection

For me everything was fixed when I changed routers last year, on two of theirs I had dropouts, slow speeds and would get stuck on Interleved path rather than fast path, which doubles your ping, hence why changing routers sorted the ping as well as the speed.

I can't speak for congestion or other factors, but as far as im aware the ISP only really handles the authentication, everything else is literally handled by openreach, the line is openreach as is the modems at the cabinet and as far as I know the exchange.

The path beyond the exchange is determine by Vodafone. If it is not big enough the end users suffer from congestion.  Unfortunately Vodafone are slow to increase the capacity which is why so many users complain. Increases to capacity no doubt cost money but the bad publicity must make it more difficult for Vodafone to build up market share.

I am glad to hear that you router is able to connect to the cabinet better than the Vodafone one does. Which router do you use?
