Appreciate any advice.

Shifted to a new suburb in Dundin and in additional to sticking with Orcon for broadband went for a complete homeline package. Before we shifted was getting around 3-5Mbs downloads with Orcon and Telecom home ine.

Here is what I am getting now !

Modem Statistics

Line Rate
131 Kbps downstream
156 Kbps upstream

Attainable Line Rate
300 Kbps downstream
200 Kbps upstream

Noise Margin
12.6 dB downstream
14.5 dB upstream

Line Attenuation
82.0 dB downstream
41.1 dB upstream

Out of 3 modems that worked at prior address, 2 will not pick up adsl signal at all.
No faster in non peak times.

I went door knocking along the street to discover houses about 8-10 away on either side of us are getting around 4 Mbs.

Complained to Orcon but getting nowhere fast.

Requested their report from Telecom.

Your Telecom Problem Number is SDXXXXX.
TCNZ COMPLETED XX-XX-2010 XX:XX:XX Port has been reset and profile has been changed to long reach profile, however speed did not change much, checked attenuation is very high 82.5/37.7, suspect user is more than 5km from exch, user may need to change plan as they are out of the range that Telecom can provide high speed internet service, thanks.

qd.parameter.actual.bitrate kb/s 148.0 156.0
lqd.parameter.attainable.bitrate kb/s 320.0 176.0
lqd.parameter.rel.capacity.occupation % 57.0 89.0
lqd.parameter.attenuation dB 81.0 37.5
lqd.parameter.noise.margin dB 12.5 15.1
lqd.parameter.actual.psd dBm/Hz -41.0 -38.0
lqd.parameter.power dBm 10.5 8.8
lqd.atm.traffic.rate.title octets 4.64693241E8 6.9977384E7

All Im getting from Orcon is that as my line attenuation rate is so high I must be a long way from the exchange.

To quote them "We've had your line investigated by our supplier and found that the cause for your slow speeds is due to your line distance from your phone exchange. Your line stats indicate that you are more than 5km away from your phone exchange and the service is basically borderline operable and near its limits"

Well my immediate neighbours in either direction must be even further away from the exchange but they are not borderline operable!

Is there any thing I can do?
Requested a technician but one week later still waiting for a reply.

Yeah that line attenuation is off the chart.

What exchange/cabinet are you on?

Orcon will not sent out a technician to check the house wiring as its all about the line.

Advised me that cabling in my area from the 1940s and could be looping all around the place before getting to the exchange.

Told to go with a wireless provider if I want better speed.

Will check attentuation of the neighbours though.

sounds like dodgy house wiring.
get a tech to check the line speed at the grey telecom pole. and also the actual speed your getting in your house.
That will instantly tell you if the problem lines on your own property in your wiring, or in their network.
Also just to make sure - you dont have anything plugged into a wall socket with no ASDL filter? sky, fax, phone, etc etc?
I had 76db noise and basically no internet, turned out to be bad house wiring.
good luck
