Is there anyone from Slinshot that can help?

I have been a customer at my previous address and service/speeds were great. mI then moved in with a mate. He had Vodafone and the speeds were being throttles l;ike crazy at peak so I suggested switching to Slingshot.

The Voda line speed was 15Mbps...Not too bad - but could be better - we are 1.1 km from a cabinet and not much further from the exchange.
The switchover took a long time as the online process did not handle going from a Naked connection correctly and no one called to get the missing info till I chased up after 10 days.
Anyway...switchover occcurred and we has 13Mbps max line speed (I am refering to the modems max download link rate (Netgear D7000 and the Slingshot issued one are about the same). Gave it 15 days to 'bed in' and no speed increase so rang slingshot and they agreed to drop us back to ADSL as the speed was not good. All good I thought....cant get great speed at 1.1 km....but when the change to Slingshot ADSL occurred, the max connect speed was now only 9Mbps. Rang Slingshot and they got Chorus to check. Chorus say no issues.....even though the lines a few weeks before provided ADSLK at 1.5MBps or more?????
Was not stuck between a rock and a hard place so asked Slingshot to bump us back to VDSL...hoping to be back at 1.5MBps or better...but no...No the VDSL max rate is only 10000 kbps.

FYI....when we had the Slingshot ADSL, I tried removing the master filter incase it was faulty...no apparent change. I have tried 2 modems and both give very similar sync speeds.

Where do I go now? Slingshot support have tried to help, but now I am getting frustrated (trying not to blame Slingshot as I believe it is a Chorus issue).

All I want is internet at 1.5MBps or better so my flatmate and I can both stream at the same time....

Please help Slingshot.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

There is no way you'd get VDSL2 with such poor stats so I don't know why anybody would try.

As for sync differences it's possibly because one is a UCLL vs one being a Chorus wholesale connection.

OK...so who do we go to to get the better speeds? Who else shares the same gear as Vodafone? My flatmate wants to go to BigPipe, but that would be the same....

The other issues is we had VDSL via SlingShot only 2 weeks ago and yet now it is slower...Hopefully it will speedup a bit over the next 10 days.

I'm very confused by your post.

It's impossible for you to get better download speeds on VDSL2 than ADSL2+ with clearly such a poor connection. If you want faster download (but slower upload) move back to ADSL2+

I may sound confusing...but I asked to go back to VDSL as it did have a better speed than the ADSL (after we were on VDSL).

To me, it appears something changed during the change from VDSL to ADSL that has made the line quality worse.

I will try and sum up...

I move in to flat - we are on Voda ADSL at 1.5MBPS
Want faster speed on not in fibre area so change to VDSL
VDSL speed only 1.4MBps so as per Slingshot info ask to pay ADSL rates. They then changed us a couple nights later back to ADSL (I had no notice and only realised as modem could not sync until I ran setup and it connected via ADSL)
SlingshotADSL only 0.9-1Mbps so asked slingshot to move us back to VDSL (as speeds were a bit better and was ok paying $10 extra per month for the higher speed - even though it was low).
VDSL reconnected today but only 1.0 MBps

This has all happened over about 2 months.

Does that make sense?

All I wanted was about 1.5 MBps (more would be ideal). We left Voda as speeds dropped at peak time (suspect heavy contestion.

are your talking in Mega Bytes per second or Mega Bits per second

they are very different things

I prefer talking in MBps (Mega Bytes) but I did quote Mega bits in the opening. I am aware there are 8 bits in a byte and that there is a bit of overhead so I alway try to work on the actual download rate (in MegaBytes) is about a tenth of the modems max connection (which is reported in megabits).

i.e. my modem has a max connection speed of 11Mbps so my torrents should be able to hit 1MBps (assume good seeds etc).

FYI - I am a Sys Admin and been playing with PC since Apple ][e and PC jnr days, so I agree that many do get confused and expect speeds 10 x what they actually get.
On VDSL now I am getting a bit more than ADSL 1 max speed. On ADSL yesterday I was getting ADSL1 speeds...but I can confirm I was on ADSL2 annex A

Here are some details for the current VDSL modem...Wish I still had my old ASUS to check the noise on each frequency to see if that isolated the issue.

the problem is you are talking in a measurement that computers use, not a measurement that broadband technology uses. Internet connections are measured in Mbps (megabits per second) so it would really help if you used those.

i suspect there is nothing you can really do to improve your connection. its more than likely a combination of crosstalk and a degradation in the copper lines.

The likely issue as someone pointed out is a difference between the gear at the exchange that Vodafone used and the gear that slingshot use...

I do not think a phone line would degrade that much in 3 weeks. We were on ADSL and had 15Mbps we went to VDSL (and got 14Mbps) then back to ADSL and the ADSL speed was only 9Mbps. Now I am back on VDSL but at 11Mbps. During these changes we have had VDSL twice in a 3 week period (both times with Slingshot. 3 weeks ago it was 14Mbps...now it is 11Mbps (admittedly I have not waited the 10 days for the automatic systems to optimise the line.

The other thing I wonder is what the line quality is like in the cabinet or exchange as it seems to drop each time the change the form of DSL.

different port at the cabinet/exchange, different pair between the cabinet/exchange and your place.

port yes...different pair....not so sure unless changed out at street.

But surely since ADSL sppeds went down by almost half that should be a problem...yet Chorus say everything is fine???? Only getting 10-11Mbps is not a great speed when you are only 1.1km (cablewise) from the exchange. even the speed calculaters working from SNR and attenuation say I should be getting closer to 18Mbps.

All I can say is hurry up fibre....until the plastic starts deteriorating in a few years....

like sbiddle said if you were on vodafone gear that could explain the speed difference you are seeing now.

Now that they have a 9dB margin on VDSL it may be more tollerable on a line that is that bad, compared to the 12 that they were running. Perhaps wait till the change over to the new bandplan is complete and try vdsl again?

You need to remove the confusion with your stats - speed is always measures in Mbps or kbps.

Bits are the measurement of speed.

Bytes are the measurement of storage.
