Self taught Noobe here. Just recently switching to Fiber from cable. Reading that my GT-AX1100 should be able to replace their router. As far as I can tell I need to have the PPPoE credentials and swap VLAN tagging. I have found where to setup the VLAN but not to switch from DHCP to PPPoE. The ISP is Kinetic which I believe is like CenturyLink. I have the most recent Merlin uploaded on the main and node (RT-AC88U) hardwired. Any help would be greatly appreciated.
