If you have FTTH (Fiber To The Home), you will have what is known as an ONT (Optical Network Terminator) in the home. These ONTs provide DHCP through a Cat5e or Cat6 cable going into the wan port on a residential gateway like the FiOS Quantum Gateway (FIOS-G1100). One can simply take this cable set Plume to Auto mode and connect the Ethernet cable coming from the ONT to the Gateway pod
You may need to keep the provided residential gateway if it is also required for additional services like Set-top boxes (STB).
Please note that this situation does not apply to Verizon FiOS customers having the service provided through DSL, DSL Pair Bonding or Cable internet service. Follow the instructions here for Verizon.
