Hi Everyone,

I realise this has been covered multiple times, but I just wanted to get an opinion on what to ask before I call Spark. I'm getting 30Mbs down, but less than 1Mb up on a rural VDSL connection. I'm about 1.5km from the cabinet (as per the road). This has become a huge issue with two kids/wife/myself attempting to carry out video conferencing while in lock down. For all four of us it's essential work and school requirements. Using a Vigor 130 modem connecting to Ubiquiti wireless equipment.

Any thoughts appreciated.

Ive attached line stats below:

Thanks!

Hi, so I the speeds you are getting could be a little better for 1.5km, my guess is its more likely 2km of cable.

I take it you internal wiring has be checked, the modem should be connected to the inbound line that goes direct to the modem, no other T's, taps or phones connected, if there is a phone then all other wiring should be behind a master filter ideally sited at the ETP or direct off that. Something makes me think you have already done this.

Next option, can you move the modem closer to the cabinet and purhaps use a p2p link to drop it to the house. Without understanding your rural circumstance, maybe a neighbouring property where you can have the line moved to and a p2p installed?

Thanks for the reply. I forgot to add in my initial post..... House is a new build, about 3 months old. I have a single dedicated line coming into the garage where the modem is connected - no other phone connections in the house, my house is only about 50m off the road. I've looked at some form of p2p connection but thought I would persue the VDSL connection to start with as my download is acceptable. Do the figures sound reasonable or is something wrong? Thanks

DM me your landline number/account and address, I'll have a poke at the maps.

for a 29db connection though, it looks like you have drawn quite a nice clean pair, US0 (ADSL Upload) is only about 1mbit at VDSL Power Levels. US1 is a fair way up the bandplan which is where you will see the 'boost' in speed.

Physics defines a pretty clear drop off over distance.

Looks like it might be a vectored line, which unfortunately do tend to suffer in the upload department on longer lines due to the 17a power levels.

the bit that does interest me is the high UAS

Do you happen to have a HG659 or one with a similar Broadcom chipset? From my experience they seem to be able to squeeze out slightly better speed from longer lines while still being stable enough. They work great in bridge mode...could be worth a try just as a comparison.

Edit - as Hio says though the line does look pretty decent.

Thanks for the replies guys. hio I've PM'd you my details, much appreciated. Unfortunately I only have the Draytek which I don't think is a Broadcom chipset and an Asus modem which Ive also tried with similar results - also not a broadcom chipset. The replies are much appreciated.

Oh, and yes I'm running the vectored firmware on the Draytek.

Quic Broadband

Coatesville in Auckland, unfortunately no fibre for us in the grand plan.

Provided a more detailed response in DM, but it really is just distance based.

Vectoring is doing a ton of work on this line actually.... I'm impressed for little old coatesville!

@cyril7's math is on point as always, is correct regardless of looking at DELT or physically drawing it :)

My best advice is to play with a broadcom modem, you might find the gains worth it. PPPoE Bridges real easy.

Hi, so based on Troys confirmation re the line length, next option as mentioned is to see if you can shorten the cable length with a p2p link back to somewhere closer the cabinet, are there any options on that front that you can immediately see?

Some of our customers have bought a second ADSL or VDSL connection for the next 1-2 months. Kids / learning on connection 1, home business on connection 2.

Unfortuntaley I don't see anywhere that would be feasible, I have alot of trees around and up quite a slope to the cabinet. Most of the p2p solutions require line of sight which is quite difficult. I might just have to wait for mid frequency 5g (I can dream). Thanks for your suggestion though.
