Neori: I would say it is the line adjusting itself, especially if you are still within the initial 10 days of installation.

2nd day in for me. Hoping my DLM profile changes. Haven't had any CRC errors at all which is nice.


Where does one see the current profile?



I don't think you can see your profile. It's more of a self observation/monitoring of the connection. Basically "feeling" and seeing the changes. Have a read on the below VDSL performance thread in the SNAP area. It's really informative.

http://www.geekzone.co.nz/forums.asp?forumid=90&topicid=105744

Main thing I'm looking at are the below;

SamF:

Profile

This is the Bandplan profile that your connection is currently using.  This will be either 8b (50mbit max) or 17a (70mbit max).  At this point it appears that Chorus will not manually change your Bandplan profile and the only way to get to a 17a profile is if DLM determines that it is appropriate to do so. *4  According to Chorus VDSL documentation, line attenuation must be less than 2.75db (in other words; you are less than approximately 200m from the cabinet) for 17a to be activated, however attenuation figures as high as 7 have been observed prior to some lines being swapped to 17a.  Note that this is different to your DLM Profile (see below).


SamF:

DLM Profiles
 
There are 9 different DLM profiles which may be used on your line. *3  In the list below, the first item is the name of the profile, the second item is the latency introduced by Interleaving on the profile, and the third item is the INP (Impulse Noise Protection) figure. 

 

DLM-1     1ms  0INP 

DLM-2     8ms  0INP 
DLM-4     8ms  1INP *9
DLM-6     8ms  2INP 

DLM-3   16ms  0INP 
DLM-5   16ms  1INP 
DLM-7   16ms  2INP 
DLM-8   16ms  4INP 

There are also 2 Target Noise Margin (TNM) settings per profile: 9 & 12, but apparently the 9db TNM is only active when on the 17a profile. 

 



Profiles are only changed one level at a time, you won't for instance, go from DLM-1 to DLM-4 in one step.  So either TNM will be changed or INP and/or Interleaving latency will be changed as a result of a profile change.] - Note that while this used to be the official policy, it appears that this has recently changed and some new connections are connecting directly at DLM-1 and in some cases even 17a!

Note that the DLM profile is different from the Bandplan Profile which determines the maximum attainable sync speed for your line (see above).  Sync rates are not directly managed by DLM.

Mine's been fine - no reliability issues and pretty consistent download speeds.

Slightly higher latency when gaming, but not show-stopping and the router is only "ok" (what did I expect for $20!?) - my download speeds are noticeably decreased over the WiFi compared to wired, but I will be replacing it sooner or later.

Netflix etc still working well with Global mode on.

I suppose I am very slightly disappointed that my speeds weren't better as I am fairly close to the cabinet, but 30/9 is nothing to sneeze at and obviously a huge increase over my previous ADSL.

Lower latency (than AYCE ADSL2+) by 9ms.
Torrents are faster downloading, as is everything really.

Very stable.

Speed tests generally report about 25/5 for me (which to be honest, I was a little disappointed in). My service appears to spike (example, my speed tests looks like a saw blade rather than a flat curve) - in reality I don't notice this in watching streams / gaming etc.

However, the major reason I got VDSL was to improve upload speed for work related VPNs and software license sharing over said VPN. The upgrade has lead to a huge improvement in these areas.

The technician who did the master splitter install was excellent.

Overall: Really happy with the upgrade

Speeds are great both ways. Stability is also excellent. Been a happy chap for the past 3 weeks.

I think I may be beating a bit of a dead horse on this but.. I'm on Slingshot unlimited naked ADSL, and I forked out to buy an ATA for the free iTalk phone line.

I really need the better upstream speed so at this point in time I have three real options:

a) Get a VDSL2 connection via Slingshot, change my phone number (iTalk number is for another region), and put the ATA back in its box
b) Same as above but pay an extra $12 a month for an iTalk line to retain my smartphone features, Wellington phone number and make use of the ATA
c) Move to Orcon out of spite for all the lack of information coming out of Slingshot for this entire VDSL2 rollout.


If they just hurried and released a naked VDSL2 plan with free iTalk, even at $119 like the clothed plan I'd jump on it. But these vague "soon" type answers just drive me insane.

This may have been asked many times already but I cannot find the answer . . .

I just signed up for the Slingshot Unlimited Plus VDSL and I was wondering for those who have it what modem they got with it? For $30 I'm a little worried it will be terrible

This one! More details here.

;)

It is surprisingly decent for the price IME so far - reliable and robust, though the DL speeds on WiFi are slightly worse than wired and I haven't seen quite the speeds I was hoping for, though whether that is the unit or my cabling, I don't know.

That said, I still aim to replace it soonish - probably with a DSLN66u as I prefer all in one and I have got on very well with the Asus gear in the past.

More questions!

What sort of error statistics are people getting with their VB104W and the Slingshot VDSL?

I will post mine when home tonight, but my CEC errors are in the many, many thousands and the others are pretty high too.

I am still getting a reasonable 30Mb/s down and just under 10 up with the line syncing at 35 according to the router stats...

Should I be concerned? Is this an indication that my theoretical max speeds are being hampered by line issues or is this a red herring?

Thanks a lot! People seem to be fairly positive about it which I'm pretty surprised about because for 30 dollars I was expecting something dreadful.
