Ok, so I ended up setting the N55U as the DMZ target from the TG, which seems to have resolved the issues with double-NAT and various other port-related issues (as expected). Also seem to be, for now at least, syncing faster, very pleased!

Just if wondering his is vdsl connection and was forunate enough to be place on 17a profile as these speeds arent achievable on 8a profile . Something for all you telecom user to think about.
Other reason why you wont get it on telecom is that they use some line compacity to drive their pot phone line off. Sip overcome his issue and give more fequencies on line to achieve things with. Piror to profile change I was getting 34.5meg/bit by 10meg.bit. So change profile has improve things lot but I can tell you DLM isnt able be done by request it will only change if DLM thinks you going gain something from it , so unless you got very good line it very unlikely to see what ive got here.

An update on my troubles with getting VDSL installed in an apartment. First off the problem has not been resolved. After Friday's fiasco of having a tech supposedly turn up and not even bothering to ring me or come to the apartment to check the install, I rang Visionstream and complained. They organised a tech for the next day (Sat).

I was called about 2pm by Peter from Chorus, I explained the situation, and we arranged to meet at my place. He turned up early (and remember this is the FIRST person I have actually seen since the original install 5 days ago) and was excellent. His knowledge was outstanding (he has been doing this work since Post Office says), and it seems the underlying problem is that I am simply too far from the exchange.

Some interesting notes:

He re-wired the splitter in the apartment just to make sure that was done correctly

He tested from the comms room and got the same result as the apartment, meaning the cabling from the comms room to the apartment is fine

He then tried 3 different pairs from the exchange to the comms room (which involved driving back and forth each time)

Ultimately he said the attenuation indicated I was 1.49Km from the exchange, which is the limit of VDSL

He said the original install should have never been done as it was too far, but the install tech's get paid for it so do installs in borderline cases

He also said that he wouldn't get paid for the work he did, even though he was on the job for 3 hours, as Chorus only pays for 'successful' jobs, and as he couldn't get VDSL going it wasn't successful

He also commented on the fact that Chorus are seeing a huge number of VDSL installs that just don't work, and that the vibe amongst the techs is that they wont touch it now, as they wont get paid for the jobs if it cannot be made to work.

So it STILL doesn't work, although I do have slightly better sync rates.

The next stage is to revert back to ADSL and hope that the service change will result in a working connection. I will be calling Telecom tomorrow to arrange this, which ironically will involve another tech to go out to the exchange. After that its seeking a credit for the time the connection has not been working.

How long are profile changes meant to take? My VDSL modem had no connection for about 15 hours starting from 9pm last night. I rang the call center this morning and it started working again not long after that. The call center guy gave a follow-up call after having a chat with the techs so I assume they did some manual changes to get my internet working again. It is also syncing at a higher speed than before. They are still going to send a technician out tomorrow morning to check my line as my VDSL connection was only installed last Thursday.

Other than that, I have been absolutely loving my new connection when it is working!

you find it will alter every 24hr generally speaking. Most DLM change occur in early hrs of morning to avoid user interruption and also it when generally the local loop is less stress with others using it. Other thing your telecom techy wouldnt of told is dont turn ya modem / router of in attempt to try speed it up as that will actually just make it think ya line is unstable and will extend time it takes to do it dlm tuning :)

Hi Simon, I remember you were posting on our Facebook page regarding this sort of thing. Please note, Telecom and Snap are selling the same wholesale product from Chorus so speed should not differ as you say it is. I don't understand your motives by posting that Snaps services are better than Telecom's but this all comes under personal preference from the customer. If you want to continue these discussions this is not the topic to do it in.

DLM is based on error count therefore if your line is showing higher errors DLM will lower the real-world speed of your line, I don't think you understand this, our customers know about DLM and the importance of not turning off your modem.

Wow... looks like you live next to a cabinet or exchange. Would you mind to post your line stats from your modem? And when was the VDSL2 connection installed (so that we can tell how far you are in the 10 day training period)?

I'm very jealous of all you people, especially Inphinity :P Those are some excellent line speeds!

I don't quite understand exactly what you're trying to say here but if you're inferring that sync speeds of Telecom VDSL2 with POTS on is different from other ISP's offering Naked services because they have POTS off you're incorrect. Every ISP in NZ uses the same profile for 8b and 17a because they're all using the identical wholesale product.

haha! Thanks for your help getting things sorted :)

I'll be very interested to see what sort of real-world speed difference I notice... I still wonder whether the way I have the TG & N55U setup is going to cause any bottlenecking, but will wait a bit longer before I fiddle too much more.

Oh, hey, any plans for Telecom to host a Steam content mirror (and maybe even make it exempt from data caps haha)?
