Intermittent Packet Loss

Hi,

 

I've just attempted to use the online chat function to talk to a technical support but after 30 odd mins, it then cancelled as I finally got to number 1 in the queue, typical.

 

I have a problem - best illustrated if I continually ping a website, such as www.google.co.uk -t, I get roughly 10 seconds of good connection, and then 2-3 seconds of lost packets/Request time outs.  Please see below an example:

And this continues in a never ending cycle - Any chance you could help??

 

I'm even struggling to have a stable enough connection to load a speedtest right now.

Re: Intermittent Packet Loss

Hello :),
Can you please post your ADSL stats by following this direct link; http://192.168.1.254/index.cgi?active_page=9116 << it only works if you have a Home Hub 2.0+ and remember to type your password in!

Also we need a speedtest just to have a look and make sure everything's okay? Use this link http://bit.ly/o8qqQ9 as it will also help you diagnose and give you a list of solutions afterwards to help you diagnose your problems if it thinks there is a problem. Could you please also copy and paste the results from the White/Black/Green pop out page including your IP profile, DSL Connection Rate and speed achieved during test.

Run a line test to determine if or not it is an external problem: http://bit.ly/tgwip

Can you also confirm if you're connected at the master socket or an extension? And what your type your master socket is according to this picture

Lastly for now, call 17070 and Press Option 2 for the Quiet Line test and where possible use a corded phone as DECT handsets can pick up electrical interference?

 

Are you connected wired or wirelessly?

Re: Intermittent Packet Loss

Hi! I tried that link and it didn't work - but found my ADSL settings

 

ADSL line status

Speed test results: 4.1mbps, estimated 8.0mbs

 

Speed doesn't appear to be the problem at all though, it's just the continuous interrupts!

 

It looks like a Non NTE5 to me and yes I'm connected via the master socket - I have been testing via a cable.

 

I can't test the line at the moment as I'm connected to the internet and have no other means of accessing the linechecker facility!

Re: Intermittent Packet Loss

Don't worry about being connected to the internet, it doesn't knock you off or have any effect on the result.

Can you also run a test at http://www.pingtest.net

Re: Intermittent Packet Loss

Pingtest:

 

http://www.pingtest.net/result/49366097.png

 

That seems to imply it's not packet loss, just hiccups of lags every 10 seconds??

 

 

Line check:

We cannot detect a problem with this line.
It may be caused by a faulty phone or equipment.

Test1 comprises of two tests

1. Best Effort Test: -provides background information.

 Download  Speed
 1163 Kbps
  
0 Kbps7150 Kbps
Max Achievable Speed

 

 Download speedachieved during the test was - 1163 Kbps
 For your connection, the acceptable range of speeds is 600-7150 Kbps.
 Additional Information:
 Your DSL Connection Rate :4544 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 3000 Kbps


2. Assured Rate Test: -provides background information.

 Download Speed
 2572 Kbps
  
0 Kbps600 Kbps
Max Achievable Speed

 

 Download speedachieved during the test was - 2572 Kbps
 For your connection, the acceptable range of speeds is 576-600 Kbps.
 Additional Information:
 Assured Rate IP profile on your line is - 600 Kbps

 

 

Well, none of those results were quite as dramatic as I was hoping for to emphasise how frustrating these hiccups are, here's a screenshot of my pinging results for a while last night if the helps - red = Request timed out.

Any thoughts? Smiley Sad

Re: Intermittent Packet Loss

Hello,

 

Your sync speed is very low for your attentuation and your SNR margin is incredibly high. Are you connected to an extension?

Re: Intermittent Packet Loss

I looked again and you're not connected to an extension. The best option would be to get BT to install a new socket. I believe that BT will fit one for free if you get an engineer round. It will give you the best speed possible.

 

You should be syncing at 8128kbps and getting around 6-6.6Mb/s downloads on your connection.

Re: Intermittent Packet Loss

Well, whilst that may be possible - this has suddenly come on from nowhere, so I'm hoping there's got to be something else that is the cause?

Re: Intermittent Packet Loss

Does the problem happen all the time or only at certain times of the day?
