Hi all, trusty first time poster here.

I have sort of had this issue resolved, but was hoping to have the process explained a bit better and some advice on whether I should follow the issue up in a few months time to see if i can get a better result.

On the 30th of April I arrived home from work to a message left on my answerphone advising my connection had been upgraded and changed to a new port.
On checking I found I had a broadband light but no internet.
I contacted the Chorus tech that left the answerphone message and was refereed to my ISP -Xtra.

Xtra looked into things, advised me the port had had been changed to was faulty and that they would get me placed on a different port.

This duly happened and 2 days later we had Internet again.

I have been on a broadband connection at this premises for the last 8 or so years. It has slowly improved and prior to 30th April I had a solid connection, low latency and a sync rate of 830/4.800 - 5.200 with corresponding download speeds.

On the upgraded port i i had a connection of 832 / 7.616, stable, but I will now post a list of the Telecom speedtests I did over the next few weeks while I was working with Xtra/Chorus to sort things out.

All tests done via ethernet, other PC's phones etc turned off or not here. ( we are normally a 70 to 100 Gig traffic a month family)

In the end I finally got informed of what had happened which is that I had been moved to a closer cabinet with older equipment. I asked to be moved back to the original exchange, which has now happened.

I am now getting a useable connection

The question I am coming to in my long-winded way is.

It looks like DLM is currently taking place, just had first restart in 3 days and connected faster than since I was reconnected.

So I am hopeful of slowly increasing my eventual stable connection speed.

However the connection I was put onto, to me, seems as though it would be much quicker but is currently crippled due to overloading or older equipment.

From the info pasted would it be a good idea to keep checking with Xtra as to the state of the equipment ?
Is it just overloading and I should forget it and live happily with my current connection? (I am rural..so was quite happy prior to all this)
Did we miss something during the last 2 weeks of frustration and should i revisit the closer cabinet ?

Thanks for your time.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

Hi there, mind flicking me a private message with your landline number? I'll take a look. Cheers

Looks like the port is set to ADSL rather than ADSL2+. Unless it is an older asam or something. I assume there will be some resolution from PMing michealmurfy.

The verdict is a very noisy line and 3km from the exchange:

Sounds suspect.

The OP seems to be saying his connect rate is fine, just rubbish throughput.

Is he on a Conklin?

Hi there,
Been away, but will try to clarify my OP.

Firstly, thanks for the test and I am putting a Master Splitter in this week.

However the thrust of my post was,

My connection over the last few years has been to the exchange, that is 3Km away.

I was syncing and getting transfer speeds that reflected 4.8 to 5.2 Mbps

I was changed to the Cabinet that is only 300Mts away.

After that change i synced at
DSL Type: ITU-T G.992.1
Bandwidth (Up/Down) [kbps/kbps]: 832 / 7.616

But my connection was terrible with speedtests of

Broadband Gateway/Modem:Technicolor TG582n
Connection Type: Ethernet
Download Speed (Mbps):0.81
Upload Speed (Mbps): 0.72

The speed only increased between 1.30am - 6.00am. maxing at around 2.9ish.

I was told this was due to Old Hardware and not congestion as I alluded to(neither Chorus nor Xtra liked the word congestion)

I then finally got placed back on my old connection to the distant exchange, which is slowly returning to its 4.0+Mbps.

I now wish I had found this site while still connected to the much closer cabinet, maybe I could have got a clearer idea from you folks of what the problem was :/

Anyway, thanks all for your time.

If I had to guess, I'd say that Chorus's DSLAM in the cabinet was limited in backhaul. Given your description of how bad it was, I'd be betting on a mini ASAM - which lines up with the max speed you said you ever got. By moving back to the central exchange, you've exchanged (no pun) a brilliant connect rate for better throughput. Good move given what you were experiencing.

Although the splitter can never be a bad move, it will probably have minimal effect given your current situation.

If you want confirmation, PM me your details and I can do some further digging. May take a few days though (I'm fairly flat out busy at the moment).
