So I'm having a running argument with Compass Residential and Chorus about whether the problem is my line or Chorus's network that is the issue.  The last Chorus tech "proved" that my router (a Siemens Gigaset sx763) was at fault, so I borrowed a D-Link N750 from work and tested that.  The Gigaset would sync at full rate but frequently disconnect and refuse to either re-sync or PPP authenticate.  The D-Link retains its connection (I assume it's autoreconnecting) but syncs at half the attainable line rate and encounters frequent DSL transmission errors that cause the connection to be virtually unusable.

Standard questions:

This is naked DSL.  There is a single jackpoint to which the router is directly connected (no master splitter, no inline filter).  As no voice service is provisioned on this line, and no voice devices are connected, my understanding is that this is considered acceptable.

Six routers total have been tried.  Five of them would simply disconnect and refuse to reconnect, the Gigaset being the most reliable of these.  The sixth, the DLink, has slow speed and high transmission error rates.

A total of - from memory - seven faults have been logged with Chorus, all of which have resulted in basically nothing - a tech comes out, fiddles with things, and then blames my equipment and leaves.  I have had precisely ONE positive experience with a chap who managed to get my sync rate from 3Mb/s to 14Mb/s by replacing some jumpers/joints, but he himself said that the line is essentially buggered and needs replacing.  (Fun fact - I've had so many faults logged that I have the cellphone number of the regional manager for the area!)

Below is a dump of the statistics screen.  I assume that you'll all confirm that what I'm looking at is definitely a faulty line, but it'd be good to have some confirmation (especially from some telco type folks!) - confirmation from ChorusVan would be an exceptional bonus (beaten only by them actually fixing the blasted problem).

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?

So it was going good this morning then suddenly bang - from 11Mb/s down to 5Mb/s (with error rates that make Office voice dictation seem accurate).

I'm definitely not suffering mid-span injection (wholesale service, and that sync rate would be impossible with MSI anyway) and it's definitely not a Conklin (I wanna say MSY/A but I cant be sure since Chorus removed the actually useful info from the maps tools - thanks guys!) and having tried multiple routers I'm convinced the issue is the line.

Has the cable from demarc to jack-point, and jack-point been replaced?




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

It was only installed two-three years ago, by Chorus.
