Please help me make sense of these VDSL Router readings. 



Previously I was on BigPipe ADSL2+ and getting 15Mbps down. Yesterday they installed Slingshot VDSL2 and my speeds dropped significantly to about 8-9Mbps. I was told by the installer that I should be getting between 50-75Mbps because I am only about 175 meters away from the cabinet. 

Can someone tell me what all these OCD errors and LCD errors are and if they would be having this effect. 

Is it normal for people to have these kind of speeds right after VDSL installation?

Is there something else that could be causing this? I have had the internal wiring checked and it is fine.

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.

[strike]your downstream attenuation is too high for VDSL, double the maximum reccomended attenuation.

Unless there is some kind of error, basically you are much too far from the cabinet to get VDSL and it shouldn't have been installed.
But if the installer told you you are only 175m, and he should know, then there probably is some kind of screw up somewhere [/strike]
ignore.
(did you just post this in another thread?)

I did but I then deleted it as it wasn't really relevant to the other persons thread and so I made a new one.

I was told that the Attenuation was only 2.5 dB since its being measured in 0.1dB by my router. Is this incorrect?

oh yes. that's right.  Pretty bizarre, but 2.5dB makes sense based on what the tech told you about your distance.

Saranis:  I have had the internal wiring checked and it is fine.


Who did you get to check it and how thorough was said check? When was the master filter installed and by whom?  Did chorus\installer by any chance measure sync rates at the road?


EDIT: I'm not suggesting it's definitely internal wiring at fault;  but there's definitely something seriously wrong with that sync rate at that attenuation.  It's extremely unlikely that DLM will fix it and is definitely unusual. And unfortunately internal wiring is really the no.1 place you need to start looking\rule out completely.  If you are 100% sure it's not internal, then log a fault with ISP, and I would be highly skeptical if they suggest DLM will fix it.

I'm sorry I don't have the information about the check, My husband dealt with that. Chorus was out here a couple times checking our ADSL2 connection and they told us the wiring was fine as well. 
Chorus did go out to the road to measure something but never told me the results.
The Master Filter was installed yesterday by Chorus.

I am skeptical, which is why I came on here, They (Slingshot) pretty much told me it was normal and that DLM would fix it in a couple days up to a week. I however have never heard of speeds this bad even with the DLM process running. I have been reading a lot about VDSL recently trying to decide if it was worth getting while we got approval to have fibre installed in our rental. We eventually went with it because Slingshot allows us to switch to Fibre mid-contract.

Oof that doesn't look great. The filter install might have been balked. If you'd like to flick me a DM with your account number I can get one of our techs to organize someone to come take a look.
