I moved into this house in 12/2013 ordered my Slingshot broadband with phone line. Not a problem until Oct/Nov 2014. That was the time when Chorus changed the power poles in our street and wired the power and phone lines to it. From here on out nothing but problems.

First my phone line was dead. No dial tone. DSL still connected with a 3rd of the speed. Contacted Slingshot tech support and they had me run an isolation test. Did show nothing, so they logged a fault and sent in a Chorus tech. He went up the pole, down the pole. Phone had a dial tone again. Yay

Until a week later or so DSL started dropping and as soon as it came back on it dropped again right away. When it does connect and stays on, DSL sync speeds are half sometimes only a third of what they normally are. At this point I called Slingshot to log faults a whole 4 times and had 3 technicians here. One apparently "replaced a module in the cabinet" according to Slingshot. The drop outs are still happening.


I have two jacks in my house. One in the kitchen/dining room and one in the bed room. I have no alarm system (whether the old owner of the house had one, I do not know). I have no SKY TV. The only thing connected to the phone line is the phone and the modem router. I have tried to just plug in the modem with a line filter/splitter, as well as without the line filter/splitter. I tried my second modem. I have tried both modems with both jacks. I switched out the line filter/splitter, as well as the cables connecting the modem to the jack. 

The phone line is connected from the power pole on the street to house near the roof. I went up there to have a look if there seems to be anything wonky. The cables that I found and believe are the phone line cables seem to be fine as far as I can see. I am not a technician though.

This I would call a normal connection on a good day
Downstream/Upstream
Connection Speed 19215 kbps / 1113 kbps
Line Attenuation 5.5 db / 3.7 db
Noise Margin 12.3 db / 10.3 db


Here is an example of what I get a lot of the time
Downstream/Upstream
Connection Speed 6483 kbps / 920 kbps
Line Attenuation 7.5 db / 4.7 db
Noise Margin 11.6 db / 6.0 db

Noise margin varies greatly. The lowest number I have seen was -12, the highest number was 47.5 db. My question is where do I go from here? Is there anything else I should do to find out where the problem lies or is logging another fault with Slingshot my only option?

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?

joker97: Install a master filter?


If the problem is indeed a line fault, somewhere outside of the house will the master filter do me any good?

johnr: First step make sure inside the house is OK


I thought I did what I could with isolation tests. Using different modems, jacks, cables, filters etc.

isolation tests dont do anything about inflections between multiple jackpoints.

to do a proper isolation test you would need to connect the modem directly to the incoming wires at the ETP. which would rule out the house wiring completly

or install a master filter and dedicated jack-point which achieves the same thing

Depending on where you are (right in the middle of Oamaru?) you may even be able to get fibre.

Unfortunately Slingshot cannot provide me with Fibre. I tried.

Slingshot cannot, are you saying you have fibre available and slingshot simply dont service the area?

Lots of other providers, have you asked them? All of Oamaru township appears to be covered.

That is the case according to Slingshot.

The only ones I could find that service the area are Spark and Vodafone. 

The thing for me is that so far I have been pretty happy with Slinghot's service. If the DSL issue can be fixed I would rather stay with them. I only applied for their Fibre plan because it would have cost me as much as the ADSL plan I have. So why not upgrade. But fact of the matter is I do not need more speed. What I need is unlimited data for the lowest price possible. So far that is $89 per month with Slingshot. While more speed would be nice at times, the speed I have is good enough for me. 

Therefore switching to other providers would give me more speed (which is nice but not needed), but would also cost me more $$

In that case, I would talk to Slingshot about upgrading to VDSL. I don't know their plans, but it should be the same price as ADSL, and they install a master filter for VDSL, which should rule out any wiring issues.
