Hey all,

I'm current on ADSL2 with Iconz and that's for what it is usually a very stable connection.

The current sync rates are:

Down Up
SNR (dB): 12.4 15.5
Attn(dB): 25.0 10.1
Pwr(dBm): 19.7 12.4
Max(Kbps): 15596 945
Rate (Kbps): 12474 945

I'm using a Netgear router in which I can tweak the SNR margin, so I'm aware that I could probably increase the down speeds a bit to ~13.5-14 Mbps (from past experience).

Also, the house has a master filter installed are as far as I'm aware we're on the Karori Exchange.

Now, I'm switching ISP to Mynxnet and when they ran a prequel at my address it came back with this:

lineAttenuation: 9 - 9 dB
downloadRate: ADSL2+: 14.8 - 14.8 Mb/s, VDSL2: 17.6 - 17.6 Mb/s
uploadRate: ADSL2+: 1.2 - 1.2 Mb/s, VDSL2: 7.2 - 7.2 Mb/s

So we thought we'd give VDSL a go --- being aware that the Down Attenuation I have with 25dB is quite high for a stable VDSL connection to occur. Yes, it would have been very slow VDSL, but I mostly care about an improved uplink speed anyway, even 2Mb/s upstream would have been worth it for me.

This morning the install was happening and neither my new VDSL modem nor the Tech's test gear would even handshake properly.

When he climbed up the pole he said that the wire pair I'm on is used by a bunch of other terminals and that'd probably be causing the issues with the line. My (maybe naive) question of either switch me to another wire or if it's possible to pull another separate wire up through the ducts from the exchange was pretty much responded to with "Chorus essentially doesn't invest into the copper network anymore". Fair enough, I'd have potentially even paid some money for a private cable to be pulled up the road for me to be used though.

Anyway, all was rolled back to ADSL with Iconz and Mynxnet put in an ADSL-ADSL transfer that hopefully goes through tomorrow or so.

I just thought I'd put the question out there to make sure I've checked all avenues...

a) Given my ADSL stats, does anyone see a chance that the issue could be something else but the line from here to the Exchange?
b) Why do the prequals come back with kind of "unrealistic" promises of VSDL --- even the Spark website just 10 minutes ago said I could get even Ultra VDSL --- sigh.
c) Any chance I can do anything to convince Chorus into doing _something_ (I'm not a network/telco tech, so bear with me not really knowing a lot about this) about the line quality (given that I agreeably have a very stable ADSL connection)?

Any feedback very appreciated!
