Broadband installed on Friday afternoon.
I came in on Saturday and tested: no dial tone/adsl.
tech comes back out monday afternoon and now testing tuesday morning I finally have services.
My broadband performance is unusable.  

Sync rates from modem:

real world national speed:

real world international speed:

real world international speed:

wow - what a shocker! totally unusable.
I used to sync at 16-18Mbps with Orcon a year ago at the same location and consistently get real world international download speeds between 12 and 16Mbps down.
The soft phone was a bit flakey, but hardly used it.

Getting a call back tomorrow from the throughput team, so I hope they can work some magic otherwise I will be forced to quit and try Orcon.
I am 1.7km from the Airedale St exchange so I reckon I should be getting around 12Mbps sync minimum.

This is disappointing, I was psyched for the new double data plans!

What annoys me too is that there's a VDSL2 cabinet about 75m away but Chorus said it's not feasible to connect me. That sucks, I would dig the trench or pay for it to be dug!

UFB is too far away, ugh!!

What modem are you using?

Post the line stats from the modem admin eg: line attenuation, noise margin etc.

Possible your area has been cabinetized and you are getting I think its called midpoint injection (check sbiddles post). Otherwise it could be packet loss. Lol you need to start working the problem before straight off saying you will switch providers.....

I couldn't see where the line stats were, I am away from home right now. I turned on remote admin but forgot to write down my IP doh!

You are right, but the level one person started to tell me my speeds were great (!)
Then put me on hold for 5 mins to find the speedtest tool.
No mention of midpoint injection from them, but I guess that is not to be expected.
I will search for the sbiddle post. Hopefully an easy fix!

Will the line attenuation and noise margin figures reveal if it's midpoint injection?

What will Telecom do if it is?
Are they up front and admit that midpoint injection exists?

Midplan injection can't occur with Telecom as your ISP since Telecom only use wholesale services from Chorus, they don't have their own ISAM's.

Assuming you are within a 10Mbps zone according to the Chorus SAT your internal wiring is the first place to look.

who can check my internal wiring? the throughput team?

I wasn't asked if I wanted 'wiring and maintenance' when I joined :S

are my line stats showing anything of interest? - don't know how to read them/what to look for.

WHAT?! Are you saying old wiring could be to blame? Well I never....

But seriously, coffeebaron is the man to PM

edit: 29db would put your line around 2km-ish I would guess, but you say you are closer. So check for bad joints, old jacks etc.

With 29dB downstream line attenuation you would normally expect to be getting around a 16Mbit down line rate like you got on Orcon.

Like the others have mentioned it could be an issue with the phone wiring in your home.

However, you say a you had a tech come out to reconnect the line? It's possible the tech muffed the connection of the line to the house, so it's not connected 100% properly or maybe bad connection at the exchange/cabinet end.

I would have another go at getting Telecom to book a Chorus tech to come out as test/fix it.

If that doesn't work bring in the big gun: Coffeebaron!

trakman: thanks chevrolux, I need to make the coffee baron an Ethiopian Single Origin Syphon filter ;)

Yea, that might earn a discount; thought beware, a bad coffee and I double my price :)
Hit my email but if you would like some further help and read my signature below.


Coffee Syphon:

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?
I install - Naked DSL, DSL Master Splitters, VoIP, data cabling and general computer support for home and small business.
