Seems that when I am on Slingshot I got a much slower sync speed/Max rate from Telecom/Spark. And a thing looks like exchange just two houses away, I have master filter installed and an N66U modem and the max rate I get now are 11Mb/990Kb? So looks like I am connected to different exchange quite further away?

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.

Might of been connected to the wholesale network and now moved to unbundled and copper lines don't always run direct to the hardware, The copper will still be running to the same location

Thanks Johnr, how do I check for that, I know the Chorus Map, but that only covers Chorus map, otherwise on that map I am on the >20Mb zone.

Hey OP, I can take a look if you like. Flick me a message with your account number and we'll see what's up

Pretty straight forward - Spark's hardware is run with a SNR of 12dB, whereas Callplus' LLU hardware is run with a SNR of 5dB. This means that the hardware can use a higher range of frequencies before it hits the "too noisy" margin set in the hardware. The end result is that on LLU gear you'll generally hit a higher sync speed than on Wholesale gear, but with the trade of of your line being easier to drop than a wholesale line due to noise interference.

Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

Except the OP has seen the opposite - a sync drop when (possibly) moving to ULL. From memory they run 6dB noise margin. A possibility is mid span injection where ULL gear is connected through a Chorus cabinet, meaning a longer physical line and higher crosstalk, but this isn't seen terribly often any more.

Best to wait and see what SS diagnose.

Except the OP is complaining about sync being lower on slingshot than spark - which makes it more likely they may be on LLU gear in the exchange vs a cabinet with wholesale...

EDIT: lol, beaten to it.

Heh, sorry, right you guys are - skim reading doesn't always help.

In which case I'd say yeah, you guys are probably spot on, and whoever put in the service order probably didn't notice the broadband enabled cabinet in the middle of the run, instead provisioning it via LLU.

Lower speeds can also be put down to lack of interleave on a poor line and modem interoperability in general.
Does the OP have any actual before/after figures to evaluate?

Midspan injection problems only affected early UCLL connections back when there was no provision for UCLFS.

Not with any numbers with Spark / Telecom unfortunately, but I remember it was like 17-18 down and 1Mb up.

But I have a screen shot right before I moved from Slingshot to Spark from Feb/2014, using a TP-Link TD-8840 :

Then there is another right after I moved from Spark to Flp Apr/2015 with a Telecom supplied Modem :

Both are OK speed for ADSL 2+, but now I think I am using a much better Modem (DSL-N66U), but get a much lower speed when moved back to SlingShot (taken today):

I'd suggest trying the other modem again to prove the Asus is okay.

Probably a good idea, this modem does seems had a few issues during last couple of weeks and I have to restart it a couple of times to get internet working.

After simple restart the modem, I got better speed:

I have a similar question. When I got ADSL installed Chorus accidentally connected me to Spark and connection was great with no errors. When I discovered Slingshot Global mode wasn't working was when I worked out I was on Spark and not Slingshot. Now I'm on Slingshot connection is OKish, but I do have heaps of errors on the line that I didn't see when on Spark.

Just wondering why it would be different Spark vs Slingshot?

Cheers
