My VDSL connection isn't feeling as snappy/responsive as it once did, for a lot of websites its as if DNS resolution is taking a long time. At first I thought it might be Sparks DNS servers playing up again but changing to Google's DNS servers made no difference.

Speedtest suggests I'm getting close to line speed:

I did a tracert and think I'm getting some unusual results, but am no guru.

Tracing route to nzherald.co.nz [203.99.67.67]
over a maximum of 30 hops:

1    <1 ms    <1 ms    <1 ms dsldevice.lan [192.168.1.254]

Trace complete.

The Round Trip Time on hop 2 seems a bit high to me, any ideas what might be causing this?

Modem is the stock TG589vn v2 but I'm also getting similar issues with a Draytek V130.

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?

Welcome to the wonders of DLM. Unfortunately all you can do is wait.
Hopefully it won't last too long and you get onto a better profile sooner rather than later.

The second hop is the bng and it always deprioritise icmp traffic. So that's pretty normal.

Apart from that the traceroute looks typical to me.

Got VDSL a week ago and at first I enjoyed speeds of 43Mb/s.

However, a day or so later it started dropping and now I am lucky if I reach 20Mb/s.

Are they using ASSIA for dlm and who can I speak to about this?

Please start a new thread and answer all the questions above. Your question is pretty meaningless in the context it's in without a lot more information.
