So, since I got VDSL from slingshot, I've been fiddling around with my wireless router to get the best signal and recently realised that my downstream speed has gone down from 45Mbps to around 30Mbps. I reckon that might be because of the countless rebooting of the modem in the process, interfering with DLM. Is there any way to reverse that? Should I wait? How long will that take?

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?

They advise approx. 10 days for the DLM to do its work with no reboots etc.

To Fix:

1) Call slingshot.
2) Ask for a port reset at the DSLAM.
- If the CSR doesnt know what to do or will not, ask for someone else.
- Be adamant.

3) Wait.
- You should see DLM start all over again and likely you will start off on a better latency as well as speed profile.

In future be careful. :)

DLM sometimes will get stuck or take longer than 10 days.

Easier to port reset for very fast fix.

DLMs dynamic nature means you may not ever get that speed back.

you need to be careful with vdsl.

You say you moved your modem alot, do you also mean you put one of those horrid extension leads on your line....

No I just rebooted the modem. Wiring and filter installation was done by Chorus guy. My modem still says attainable rate downstream is 50Mbps. It just looks like the downstream speed is capped at 30Mbps.
