Thought I'd share my VDSL2+ experience over the past two months since hooking up for anyone that is looking into getting it and providers etc.
My ISP is HD (http://hd.net.nz) and I'm currently on a normal VDSL2+ connection and get my landline from Telecom.
Anyways I signed up about a month ago for VDSL2 at my old residency. At the time we knew we were going to be moving but unsure how soon ( could've been 1 month, 3 months etc.. ).
My experience at the old location was actually a little bit poor. The house wiring really showed when switching to VDSL and our download speeds dropped from 16mbits to 8.9mbits on down speeds but our up speeds increased to 5.9mbits which was quite a nice boost. This was in the Albany area and we were 1.7km from the exchange ( no cabinet ). HD was very helpful and was ready to get Chorus to come out and install a master splitter. The cost was a bit much and considering we were going to be moving I held off.
Fast forward four weeks and we're moved into a new house that has a master splitter and Cat5e star network to every single room. HD said our VDSL2 speeds would be around 22/10 given the distance to the cabinet. Today we finally got the connection moved over due to some Chorus mess and we're actually running at 40/10 which is nearly full line speed.
So far speed tests indicate HD is really giving us 100% our attainable rate nationally and internationally we're getting about 6 down and 6 up which compared to our old ADSL2 is really great ( was normally like 2-3/0.8 on Telecom ADSL2+ ).
I think the wiring of a house REALLY begins to massively show when it comes to VDSL and encourage anyone getting the service to make sure you have a master splitter installed otherwise you're likely to reverse in speeds and go slower.
Sadly, but not really, we're not going to be on VDSL2 for long as our UFB install should be coming in the next few weeks!
