Hi All,

Looking for advice with respect to line speed on a Slingshot ADSL. I live in a rural area that in the last year or so had 2 new RBI cabinets installed along the main road.

When the RBI cabinets were installed, we appear to be the most unlucky in that we are roughly equally placed between them. Although we are 5.7km from one and 4.7km from the other.

Currently i get a sync speed of 2.7mbps down, and believe that probably equates to being connected to the cabinet 5.7km away, and that if connected to the one 4.7km away I could maybe expect 5mbps plus. When speeds are this low, an extra couple of mbps is everything!

We are on ADSL2, we have a master filter fitted and when I had a line fault in the past Chorus tested the line at the gate and indicated max speed there was about 3.5mpbs.

I have been speaking to Slingshot about this, and after a couple of good conversations with the tech support team, I ended up talking to the connections team. Now lets start by saying the person on the line really didn't care about my questions and desire for more speed, however I'm pretty sure what she said was wrong... can anyone comment on the following for me:

* She said we are connected to the Bombay exchange and only that will determine line speed
* When i indicated that I thought i might be on a cabinet that aws not the closest to me, she corrected me, indicating the cabinet distance made no difference
* I indicated that the chorus network capability map doesn't seem to agree with that, and basically she said, tough, chorus say you are on the closet one.
At that point I gave up!

Am i just asking for the impossible, to see if I can maximize line speed by getting connected to the closet cabinet to me? When the tech support team rain a line provision test, it indicated that 5 - 7.5mbps should be possible.

Thanks in advance for your responses!

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.

Heres a rural line, which currently bypasses the cabinet (until the RBI installation is finished) going about 4.5~5 KM to the exchange.



Your really not going to get much higher than 2~3Mbit at best there.

If a prequal is coming out at 5~7 likely the prequal is wrong, or your information is wrong on distances.


You already have a master filter installed, so your already doing your best to squeeze out what you can.
Another thing you can try is different modem chipsets will sync differently.

I have a draytek sitting here which will get 1~1.8mbit, a technicolor which will do 2.3~2.5 and a good old 604T which will squeeze a good 3~3.5mbit (although is on its last leggs and not worth using.)

at over 4~5KM, dsl will never do well. no way are you going to break 5mbit, nevermind 7mbit.


On LLU you might be able to squezze a little more out, but given Your cabinet is there, that would not be possible.


Post your line stats.

Firstly you need to absolutely confirm which cabinet / exchange you are on and how far away it is.

Secondly posting some line stats (from your modem) on here can help us diagnose your issue.




You can obtain faster line rates if you:
1) Ask for interleaving to be disabled (called "fast path"), it may however be disabled already.
- This is at the risk of stability and impact of errors.
- Interleaving when on, sacrifices sync rates and latency.

2) Install newer wiring and use a master splitter.

3) Use a more powerful and better quality modem.
- Ones with broadcom chipsets seem to work better most of the time and often have options to tweak SNRM via CLI or GUI.

To answer your main question - no, it's not possible to change cabinets. The MPF (copper) running to your property and all others nearby will follow a certain path, so changing this is physically impossible unless you've got a big budget.

You're probably within a wireless RBI area there, that's probably your ultimate solution if you want better performance.

^ This too.

But just remember OP, while wireless RBI is likely to be faster, the data caps options are depressing compared to fixed line and might not be a good alternative if you are a heavy data user.

Thanks all for the responses.

My sync stats are pretty similar to those posted by hio77 - particularly line attenuation and snr.

I do have a couple of other modems at home - so will give them a try to see what I can get out of the existing connection. I'm also going to have a good trace of the line through the roof cavity to make sure there minimal joins etc

I am quite a heavy user (200gb+ a month) - so at the moment wireless isn't really an option for me.

I guess moving house at some point in the future is my best option!

Rereading your first post, you are served off the exchange and not the cabinet it seems.

Ild double check slingshot dont have LLU gear at the exchange, you could get a profile that runs on a lower snr however other than that, tweaking around at your end is your only real option to improve things.

It is always possible that you're on ULL gear from the exchange and could be better off on a cabinet. Without further stats that PeterReader has aasked for incl sync stats it's impossible to know.

Sure - I will post all of the stats as soon as I'm at home to connect to the router.

What I can tell you for now:

- Slingshot Unlimited Broadband
- ADSL2+ Annex A
- Your modem DSL stats : TBA 
- Medhurst Road North - Bombay 
- Rural
- Slingshot said Bombay Exchange (but i know there are cabinets at the junctions of paparata / pinnacle hill road and paparata / axtens road.)

Appreciate the comments so far.

That max Width on geekzone strikes again.

are you snr tweaking there? 12/8 seems like an odd combination.

Yep sorry had a bit of trouble with the image - think its working now!

I haven't done any tweaking, in fact when talking to the slingshot tech the other night we reverted the modem to factory defaults and I only put in the basics to get connected again.

Is there something i should be looking to change?

Looking at the maps, your most likely connected to BOB/B (Pinnacle Hill road) and Not the Exchange which is a good 6 or so KM away from you.. (where Paparata and Bombayroad meet.)

Probably find your cable doesn't take the most direct route there adding a bit more distance.


generally LLU runs at 6/6, 9/9 or 12/12 (like chorus gear does.) Your line stats say 12/8 which is a tad odd, thus my querying of it.

Ild try another modem around just to double check stats there arent missreading.

Ok thanks for that - I'll try one of the other modems tonight and see what I get!
