Hi all.
Im in need of some help.
Just before xmas we brought a house and moved couple weeks before xmas,
I had vdsl installed,  (orcon) sorry dont have all the information from router as ive been dropped back to adsl2+ due to poor connection speed on the vdsl.
From memory it was max 18000 Attainable rate down and 2800 upstream, Attenuation 226 down and 126 up.

Here is a copy paste of adsl2 connection
im located in napier, from my house to a roadside cab it is about 300-450 meters depending on what way cable goes around road as im in a crescent, but i was told by orcon that im 4.5 kms from exchange, using google maps 4.2 kms so this is correct, this is why ive been put back to adsl2
attenuation line tests say im about 1.5 kms

Id like to know if roadside cabs have the copper going to them or not, then fibre to exchange,
Do my statistics of router look correct and good/bad, apart from Attainable Rate as i know its crap
And when chorus installed filter (crap, messy job with 15 mtrs of xtra length in cable), i rewired from filter to jack in the way i told him that he didnt follow and got length down to 10 mtrs
why after i assume he tested connection was i left on vdsl and no one advised that it was slow.

cheers for your help in advance

Are you testing speed over WiFi or LAN cable plugged into modem?

You have a downstream attenuation of 22 dB (note that your router measures in 0.1dB units), with a master filter and new Cat 6 cable.

You cannot realistically expect to get a good VDSL connection with this much attenuation, and you were wise to go back to ADSL.
Just too much line length between you and the exchange.
I had the same stats last year, with the same result when I tried VDSL. (line length 900m)

Why does the modem stats display two sync rates for both inner and outer pair or is that just a bug?

Anyway those speed tests look consistent with your sync rate which is within range of 22 dB downstream line attenuation.
I had a VDSL connection with similar stats that sync'd at 17 Mb/s down and 5 Mb/s up.
If it were me I would've asked to keep the VDSL every last bit of upload helps these days.
