Currently using Telecom Total Broadband.

I checked the Chorus migration schedule a week or so ago, our cabinet ETM/BU was due to be migrated to ADSL2, today the 8th April.

I noticed that we lost internet connectivity around 10am, but reconnected shortly afterwards. Chorus vans and a tent surround the phone cabinet at the end of our street.

Modem still connects at ADSL1 line speed, using multimode selected. Unable to connect using ADSL2 or ADSL2+ options.

I am assuming that as our modem is unable to connect using ADSL2, that our cabinet is still in the process of being migrated, and was hoping that someone would be able to shed some light on how long this process takes?

Hi, I would say a few days, but what is important just now is what the line attenuation is saying.

cyril7: Hi, I would say a few days, but what is important just now is what the line attenuation is saying.


Our DSL Modem reports:

DSL Noise Margin: Down 22.8dB Up 13.0dB
DSL Attenuation: Down 6dB Up 4dB 
DSL Transmit Power: Down 11.8dBm Up 12.3dBm

Does this provide any further indication?

Current linestream rate:
UP: 832Kbps
DOWN: 7616Kbps

Hi, yep at 6dB down attenuation you most definitely have been moved to a line thats around 400-500m long and you are syncing at maximum ADSL1 speed, so give it a few days and see what transpires.

But its quite normal that the migration is done in steps and with lots of cabinets cued to change over it takes time.

Oh and what modem are you using.

OK, so now 6 days since we were apparently migrated to ADSL2+, but still getting ADSL1 speeds.

Cabinet is ETM/BU East Tamaki Auckland.

I contacted Telecom who advised that our line is definitely connected to a ADSL2+ cabinet.

The Telecom ADSL2+ availability register, advises that our address is already connected to ADSL2+.

We are using a linksys WAG160N ADSL2+ wireless router, the DSL modulation tab is set to 'MultiMode'.
When I select ADSL2+ or ADSL2, the modem resets but does not re-connect. DSL connection shows as down.

Only connects when 'MultiMode' is selected, and connects at 7616Kbps down and 832Kbps up.

The Telecom helpdesk advise that it is likely there is a fault with my modem, however I am suspicious given that the representative I spoke to sounded like she had no idea what I was talking about.

Would the fact that our cabinet was possibly only migrated around the 8th April, could this migration still be pending even though all telecom sites state that ADSL2+ is already available on our line?

Happy to purchase a new modem if necessary, but reluctant to until I can get some better advice. 

Can anyone with some inside info shed any light on our situation?

Check for newer firmware for your modem

Chorus has spent $1.4 billion on making their ADSL broadband network faster. Why not spend a couple of hundred to make sure you are getting the most out of your connection?
Geekzone special price: $150* for master splitter install, normally $200+ through your ISP. Auckland and Waikato areas.
*Travel charges may apply. Additional costs may apply for complex installs.
I install - Naked DSL, DSL Master Splitters, VoIP, RBI Rural Broadband. Also a dealer for WorldxChange.

Hi, the WAG modems are notorious for firmware issues that prevent them from achieving correct DSL speeds, so dont be suspicious, only of your modem. I would run a mile form a WAG modem, but hey YMMV.

The modem has been fantastic until now, seems to sync at full line ADSL1 speed.

I am suspicious of spending a large amount on another modem until I can get some sort of confirmation that ETM/BU has actually been migrated across to ADSL2+.

Have upgraded to the latest firmware V1.00.16, but still no DSL connection when ADSL2+ is selected, only connects when multimode selected and connects at ADSL1 speeds 7616Kbps, 832Kbps.

I am on similar situation.

I am with Xnet, connected to the ETM/BS cabinet also in East Tamaki, the Chorus website said ADSL2+ upgrade completed April 2011 but further enquiry through my ISP to Chorus/Telecom wholesale, they said there is not upgrade done at the cabinet and I am still connected on ADSL1 gear (Alcatel 7300 DSLAM). If that is true, then the info on the Telecom wholesale ADSL2+ availability map tool is misleading.

I suspect if you ask others in your street you will find that they are all still on ADSL1.  The ADSL2+ migration takes place sometime after the physical work is completed.  I'm not 100% sure how long it usually takes but I would not be replacing modem just yet.  Pretty soon your connection speed will be doubled.

It will take up to 3 months to see changes. As stated here

Dates provided are when end-users are expected to benefit from upgrades. This may be up to 90 days after Chorus equipment installation dates.


The Telecom tool is just to get you an idea of when they will install the equipment, but its really just to hype you up on how quickly its gonna arrive. My cabinet wont be updated until the end of this year which sucks when I'm in south Auckland. So be grateful that your cabinet is updated

gmball: The modem has been fantastic until now, seems to sync at full line ADSL1 speed.


It may have worked fine on the old DSLAM, but there have been a number of issues with modems not connecting correctly to the new Ikanos chipsets that are being used in the new VDSL line cards.

Pick up another router off trademe then. Plenty of used ones when people sell the old one and want something new with N or USB or whatever. Got one for the uncle for $10 a while back to replace their dynalink.
