For a modem/router to connect to the NBN, it needs to have a VDSL port, so you will need to upgrade if your current hardware is missing this port. While most plans will give you the option of bringing your own device for the connection, you’ll also have the ability to buy one directly from your NBN provider. For the everyday internet connection, these modem/routers will suffice for your connection, though you may want to consider buying better hardware if you’ve signed up for a fast NBN plan – just ensure that it’s compatible.
