I've been asked to join a group of game streamers so I rang 2Degrees to see if anything could be done about my poor upload speeds. They tried some line refreshes as I was told on my VDSL plan I should be averaging about 3-5mbps. However nothing worked, and was advised that due to my very poor line attenuation (due to how far away from the exchange I am) I'm getting about 0.5. She told me that if I downgraded my connection to ADSL that my line attenuation would be better (?), and I may get a similar download speed while likely getting an improvement in upload. She couldn't explain exactly why any of that was the case, and I don't quite understand it, so was hoping one of you might be able to?

I'm also wondering how exactly to find out how far away from the exchange I am. I live in Featherston but it seems to be quite difficult to track down that info.

EDIT: Forgot to mention. It's a wired connection directly from the modem, no master filters or splitters used.

Thanks in advance.

Have you got a master filter installed? PM me your address and I can take a look.

Edit: Yep needs a master filter. Approx. 1.5km from the serving exchange and a couple of his neighbors are syncing at 30Mbit.

Definitely go down the splitter route.

Low upstream is often a sign of internal wiring within the adsl bands.

At your distance, if you can clean up the line, may get about 1mbit in US0 and maybe pickup an extra mbit in US1.

Just remember it is all in theory, nobody can promise a splitter will improve speeds. We can always be sure it will ensure things are in the best way to your ETP though.

Hey,

I'm new to the VDSL discussion. My current home has UFB but we've sold and moving to a new place. We were told VDSL was available but now that we're actually going through the move of services I'm told that VDSL isn't available because the property is too far from the cabinet. So we should make do with ADSL. Eeek! My teenage son is still reeling from the shock, my wife is worried about how this will hit Netflix, and I can't believe I'm going back to what I had 8 years ago.

What I've been told is that we're 900m from the cabinet and that attenuation is 14-15db and based on that VDSL speeds would likely be slower than ADSL.

Here is a copy of the Chorus stats my ISP provided me

michaelmurphy - in your reply you mentioned someone that is 1.5km and getting 30mb speeds

The main VDSL tuning thread suggests that speeds > 30mb should be achievable with 15db, as does some of the online calculators I've played around with.

(thanks for pointing out the number was in the original screenshot - now removed :-))

I'm open to any advice as to what is possible, and what I should be asking for.

help!?

cheers
Phil

Looking at that line.

Connection is sitting at 15/1.2, older technicolour which isn't quite syncing at it's best.

6db/6db snr,

i'd expect to see about 20-30mbit on that line, upload 1-2mbit. (low balling)

Checking current copper speeds on chorus's end, Not seeing any VDSL looking lines near unfortunately to get a good idea for copper quality.

i would probably remove the phone number from that screenshot...

Thanks - I've removed the number now - I missed that first time around.

I could put in a new master filter (splitter) for you if you need, its normally minimum requirement for VDSL.

I got a letter from Vodafone last week telling me they were automaically upgrading me from ADSL to VDSL and would be sending me a new modem/router soon. No mention was made about a master filter, and I know I don't have one fitted. Advice?

Vodafone much like most providers these days do chrous's recommended install process, Connection only. Master filters where required for speed, stability etc.

For longer distances, we tend to still do splitter installs.

I too never heard about master filters. My download speeds are pretty good ~20mbs but upload is less than 1mb. I'll have a look at the snr and check the box for a filter
