Good day @vanlintchris,
Thank you for providing us your feedback.
We don't usually support third party modems besides the once that we are providing.
We will appreciate if you can share the steps and the configuration that you've done to make your own modem/router to work on TPG NBN HFC here on the community page.
The steps as documented by TP-Link technical assistance personnel are as per the attachment. What is missing from these instructions, is that the router must first be up-dated with the latest firmware. To do this, connect to the modem/router through the web interface. The necesarry steps are described there and are quite intuitive. Please note that these steps are specific for the TP-Link Archer VR600 modem/router for use with TPG HFC NBN
This very restrictive disussion group does not allow me to attach *doc files, hence I cannot post the attachment
