Crazy packet loss
 

Sorry for another thread on this, but whaaaaaaat is going on with NTL recently?

If it's not to my gateway, its to a lot of routers in NTL's network ... Most of them in the cosham area seem to be suffering from spouts of packet loss, and it's seriously affecting my connection :(

I've phoned up tech support twice now, and both times they told me there was work in the PO8 area (a large area, very much doubt affecting my particular UBR as he couldnt confirm that). I feel like i've been fobbed off twice, and they probably know there are issues.

Anyone in the cosham/portsmouth areas experiencing slowness as of the past few days/week? :(....

Re: Crazy packet loss
 

The slowing down and high pings are in most areas looking at complaints on these forums.

Ye, I never used to get this much PL

Re: Crazy packet loss
 

Hi,
Are you in the cosham/portsmouth area too ?

Re: Crazy packet loss
 

I am in Leigh Park, Havant just outside portsmouth .. PO9 area and daammmm i have Packet Loss .. really frustrating for me as I only just got NTL broadband and now im in a 1 year contract for somthign that don't do what it is supposed too ... how can i play online games if i wanted too with this packet loss ?? NTL is advertised as making online gaming fast but in reality what they give us is USLESS

Re: Crazy packet loss
 

Anyone want to provide any evidence of the issues with Cosham and area please? :)

Horndean uBR 2:

--- 80.3.162.194 ping statistics ---
1000 packets transmitted, 1000 packets received, 0% packet loss
round-trip min/avg/max/stddev = 7.628/8.636/28.464/1.176 ms

Cosham t2cam1-b:

--- 80.3.161.146 ping statistics ---
1000 packets transmitted, 999 packets received, 0% packet loss
round-trip min/avg/max/stddev = 7.300/7.873/28.377/0.927 ms

Cosham t2core-b

--- 62.253.188.254 ping statistics ---
1000 packets transmitted, 1000 packets received, 0% packet loss
round-trip min/avg/max/stddev = 7.269/8.138/209.141/6.479 ms

:shrug:

Complaining without showing what the problem is doesn't really help ya chaps.

Re: Crazy packet loss
 

There was some work done on the uBR about a month ago .. This appeared to cure my issue, for a week.. now ping fluctuations are back.. i havent tested for loss extensively though. The proxies appear to be misbehaving as usual, or it could just be the problem has returned since the work. The dns issues as of late haven't helped matters ;)

I don't think pinging the uBR in my instance will prove anything, as the problem seems to lie between my house and the uBR. It's being handled way high up by NTL though, hopefully! :D

Re: Crazy packet loss
 

No probs here in Southsea with pings or PL, CSS is running fine.

And James Henry! You seem to know everything! =]

Re: Crazy packet loss
 

My problem appears to lay between me and the first UBR..

Also the packet loss appears to be an inbound problem, i get almost no packet loss outbound. Outbound and Inbound seem to use different routes too :S

Here is two screenshots, 1st one is a trace from my NTL line to my ADSL line showing no problems .... 2nd is my ADSL line tracing to my NTL line which is pretty bad. I ran the tests for quite some time to see if it improves but it did not, i only ran these screenshots for a few mins as a sample.

Screen 1- http://www.nano-computers.co.uk/stuf...ELLfrmNTL1.png

Screen 2- http://www.nano-computers.co.uk/stuf...ELLfrmADSL.png

Here is also a trace using the broadbandreports.com site.

I have tried alot of things to isolate the problem but it deffiantly appears to me that it is a NTL issue, nothing in my home as i tried the modem on its own without a router, i tried the modem using the USB and Etherent, i removed the conditioning filters too ... amongst other things nothing fixes it.

Hope this helps.... thanks for the replys guys

BTW pinging does not really prove anything in my individual case .. i always get reports back saying no PL when pinging ... also doing traces from my NTL line proves nothing ... it all happens on inbound traffic.

Re: Crazy packet loss
 

I have fond memories of helping to identify and fix this last year ;)

Re: Crazy packet loss
 

You may want to hide all those email addresses in those screen shots.

Re: Crazy packet loss
 

LOL i was thinking that yesterday but not got around to it yet, I have since given all my contacts an alias so the emails do not show incase i do future screenshots when gaim is open...

Blanking out the emails now ..... Thanks for pointing it out.

So anyone agree i have some problems ? and am I correct with where the problems are ?

Thanks

Re: Crazy packet loss
 

I seem to be suffering packet loss described as an "unacceptable level" according to my BB speed test aswell.

I'm not up on what packet loss is all about. Any ideas what I should do?

I'm in the M23 area Manchester btw.

Re: Crazy packet loss
 

first thing i would do is look it up on google

- that led me to rdhw :nworthy:

Re: Crazy packet loss
 

Thanks for the link but i have been there, .... read that - nothing of help for me there lol

Hopefully it will be of help to others

I am pretty much a good boy and do as much home work myself to solve things before i seek help on forums ...

Gaming is out of the question permanently right now due to this inbound packet loss, good job i have quit clanning before all this or i would have been way upset .... :(

Re: Crazy packet loss
 

l8nc.com to help you diagnose but bear in mind their will be some loss on the graph if you doing heavy downloading.

Re: Crazy packet loss
 

You do?

Unless you're someone else I'm thinking of :-)
What was the problem last time?... I don't think it's ever been completely fixed, just improved some what..
Now it's going through a very poor period again. Definitely feels like congestion/contention.

p.s. this being based on the fact that pings are perfect right now, at 1:30am?

Re: Crazy packet loss
 

Of course the other side of the coin is that at 1:30am most people are asleep so not using RF emitting appliances.

Don't think you're congested really, you've not that long been resegmented.

The problem last time was a very weird and near enough imperceptible RF noise problem. Was fixed but I don't think we ever got to the bottom of what the exact cause was.

Re: Crazy packet loss
 

Oohh.. well yeah it's a fair point that the source of the noise could have been turned off... Where abouts along the line was the RF noise being generated last time? I wonder if its a neighbour or something.. Ive tried turning off pretty much everything at home, cant seem to find anything there. Hope its not in the box outside, as we dont have the cable TV.. heh

Re: Crazy packet loss
 

I know this will sound a noobish stupid question ........ but what i have been wondering is ........ when we talk about UBR's would the Green Box in my street be my first UBR ? - or is that just a central connection point for my street which then travels to the first UBR ?

Just wondering so i then know if the first UBR on my tracerts is the green box in my street or somewhere else - thanks

Re: Crazy packet loss
 

I'm getting slow speeds but no major packet loss in Portsmouth (Copnor, PO5).

Actually, it looks like traffic shaping. I'm not saying it is, but only usenet and BitTorrent are majorly affected, HTTP is fairly quick.

Re: Crazy packet loss
 

if possible try multiple news providers.

bittorent is harder to judge since the nature of the protocol often is slow anyway.
