This article provides modem setup advice for NBN services to get you up and running in just a few simple steps;
You need to know the technology type used to supply your NBN service.
Your NBN technology type can be found in the Installation email we sent to you prior to your NBN service activation. Simply search for firstname.lastname@example.org nbn installation confirmed in your email inbox to find this email.
Please choose your NBN technology type below for Setup help for the D-Link DSL-4320L.
I have set up this router with my TPG NBN FTTN connection. For some odd reason, it works perfectly fine for the first 10-15 minutes then the download speed drops from 30mbps to around 8 instead. The upload speed is unaffected. I have tried resetting the router twice and also tried activating SRA.
Have you tried to check if there's a QoS that you can set based on your NBN plan?
If you haven't checked it, please test if it's going to resolve your issue.
