Hi, I've currently got an ADSL2+ line by Snap which performs fine. It's dropped around 3-4MBPS (had a splitter originally, that died and now on new splitter and no difference to figures) over the past 6 months for some reason and is now sitting ok with the figures in the attached screengrab: Now, looking at the line stats, would VDSL be much of an upgrade? Am I likely to get any benefit over the dsl I have now. Cheers, Chris

Highly unlikely. If you ask Snap they'll be able to do a prequal for you and give you an answer. *Need help configuring your Linksys ATA or IP Phones for New Zealand? Check my blog post

My stats are pretty much identical to yours, and I've also been tempted by VDSL. Keep us updated if you decide to make the switch!

Max attenuation for VDSL2 is 10.8dB Your stats are a bit meaningless without knowing if you have a master filter installed, so it's best to ask your ISP who can do a prequal. it literally only takes 30 seconds to do one. *Need help configuring your Linksys ATA or IP Phones for New Zealand?

AviZ: if you aint got pots then you wont need a master filter.... If you want to disconnect all your other wiring and have the modem plugged directly from the demarc, then no you won't need a filter. If you have multiple jackpoints and wiring in the house you need a master filter for the best performance, regardless of whether you have naked or clothed DSL. *Need help configuring your Linksys ATA or IP Phones for New Zealand?

im on VDSL with Snap and i had the almost same stats you have when i switched and at the moment i get 18000Kb down and 5800 Kb up but that is only due to Telecom 15 tears ago putting in wiring from the exchange/ cabinet that is to narrow for broadband (.4 when .6 is now the smallest used) if it was the right size i would be getting 22000 to 24000Kb down and 7-8000KB up but you would never get more than that. And im on the naked / voip plan.

AviZ: if you aint got pots then you wont need a master filter.... I see this (or similar) comments made fairly frequently. My understanding is the master filter has two roles: 1) Acts as a low pass filter to cut out the xDSL noise from the POTS (if POTS is in use). 2) Provide a direct line from the ETP to the xDSL modem that is free from line stubs, taps and generally dodgy internal wiring that cause unreliability or lower negotiated sync rates for the xDSL signal from reflections and the like. I would suggest that the only time there is no need for a master filter/splitter would be when there is both a naked xDSL connection (no POTS) and only a single modem outlet with no other daisy chained or unused outlets at all. Just because POTS is no longer being delivered to the premises doesn't mean that there is no dodgy existing wiring which would benefit from being isolated.

The biggest issue is reflections caused by multiple jackpoints in a daisy chain configuration, ie your average NZ house. The DSL signal keeps travelling along the cable and reflected back from all these jackpoints and causes performance degredation. I think a lot of people make the comment about naked DSL because plug in filters aren't necessary since there is no POTS service and get confused thinking the filter is only required to split the voice and data, when infact it serves two critical roles. IMHO a master filter should be a mandatory part of every DSL install in NZ, and if I were Chorus I'd quite frankly refuse to investigate the vast majority of "my internet keeps dropping out" calls until the homeowner has a master filter installed. *Need help configuring your Linksys ATA or IP Phones for New Zealand?

Chorus still uses .4 cable these days - .63 cable is ever only used rurally due to the fact that there is more interfernce out there - plus phone and broadband can be sent alot further distance
