I'm on NBN FTTB with a vr1600v modem. I do not use my bundled phone and have no intention of ever using it. Can I replace 'turn off' the VLAN tagging so I can use google nest? Or can I replace the modem so that I don't use it? Alternatively can someone suggest what managed switch or what router to purchase to make a google nest work? Preferably a list of choices.
