I have upgraded to an ADSL 2+ modem but my download speed doesn't seem to have changed.

- Plan is with Telecom
- I do have a master splitter installed.
- Located in Dunedin.
- The Chorus map tool says I am in a 10 Mbps broadband area
- Modem is a TP-Link w8970

The sync speed seems pretty low as does the actual download speed. Is this speed normal given my SNR and attenuation? If not how can i increase it?

thanks

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?

given your attenuation, it looks about right. give or take a bit for line quality.


as you already have a filter installed, your probably already set for as fast as you can get.


i find it interesting that your on a 9db SNR however.. are you SNR tweaking?

quickymart: ADSL1 profile?

 

Def not.  The modem reports in the screenshot above that it is sync'ed to the DSLAM using ADSL2+ modulation.

 

As everyone will say in this forum it's going to be one of the things:
1) Distance from your exchange/cabinet
2) Faulty/substandard wiring in your home
3) Faulty wiring external to your home (i.e. within the Chorus network)

If you PM me your line number I'll take a peek to see what we can see from this end.
