@Naviti . This iiNet article contains links to a selection of routers that should be ok for TPG. The links describe how to set VLAN ID for the different models. The list is not exhaustive.
You can search in Community for iiNet because I have referred users who have bought other models not on that list but have similar menu systems.
Thank you David.
Tried and no luck. Was on call with Netgear for approx 1.5rs doing troubleshooting.
Still have amber light on for internet on unit. They have asked to allow 24hrs and they will call back. If still not connected, advised to return router to place of purchase.
