My brand new ZyXEL XMG3927-B50A are coming to my house tomorrow all thanks to Shaun from A&A ISP after pay it by my debit card. But, they told me they will not support to set it up for me for G.fast service unless I order the service from them. But, I told him that I will use this new router for FTTC for now until my contract has expired in October with PN. Then will order G.fast with Zen Internet and will use this new ZyXEL XMG3927-B50A for G.fast.
But until later, I might need you (re0) to help me what the correct settings for FTTC & G.fast like PTM, VPI, VCI, Encapsulation, VLAN ID etc and where to put username / password from ISP for broadband account.
