Hello,

My Dynalink RTA-1025w is connected with ADSL2+ line mode, and shows the following stats:

Statistics Downstream Upstream
Line Rate 8168 Kbps 1041 Kbps
Attainable Line Rate 10140 Kbps 1033 Kbps
Noise Margin 12.0 dB 12.9 dB
Line Attenuation 33.0 dB 17.5 dB
Output Power 18.4 dBm 12.4 dBm

My understanding is the with a line attenuation of 33.0dB I should be getting faster speeds. Could the house phone wiring be a likely issue here going by these stats, or should I be looking at a better modem? Speedtest.net shows a download speed of around 7Mbps.

ISP is Telecom. No master splitter installed. It seems we are approx 2km from the local exchange/cabinet via the map.

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?

At 33db you are doing ok for 8mb... Could be better but not a whole lot.

A Master Filter would be recommended, if you PM me your line number I can run a line test, and if you are in AKL or WLG point you to people to do it for a cheaper price than Chorus, and if you live outside those areas I would recommend talking to the Broadband helpdesk on 0800 225598 and organising to get a Master Filter / Splitter installed.
