Is the G3100 Compatible with My Internet Service?

The G3100 is designed for and compatible with Verizon Fios internet service in most areas. It is the router Verizon itself supplied for Fios plans, so activation is straightforward. If you are unsure whether your specific Fios plan supports the G3100, confirm with Verizon before ordering.

The G3100 is a router, not a modem. On Fios, your fiber connection terminates at the Verizon ONT (the small box Verizon installed), and the G3100 connects to that ONT by Ethernet or coax. It is not a fit for cable internet (Xfinity, Spectrum, Cox), DSL providers, or satellite service.

Connect by Ethernet or Coax?

The G3100 can take its internet connection from the ONT two ways, and the choice matters. The Gigabit Ethernet WAN port supports full-speed Fios plans, while the MoCA 1.1 WAN over coax tops out at 100 Mbps. If your plan is faster than 100 Mbps, connect the ONT to the G3100 with Ethernet. The separate MoCA 2.5 LAN side is a different story: it runs up to 2500 Mbps over your home's existing coax lines, which is excellent for hardwiring set-top boxes or extenders in rooms without Ethernet runs.

WiFi 6 Performance

Tri-band WiFi 6 gives the G3100 a dedicated second 5 GHz band, so busy households can spread devices across three radios instead of two. All bands run 4x4 MU-MIMO for stable simultaneous streaming, gaming, and video calls, and backward compatibility means older laptops, phones, and smart home gear connect without issues.

Security and Network Features

The G3100 includes WPA3 and WPA2 wireless encryption, a customizable firewall, content filtering, and intrusion detection. It also supports static NAT, port forwarding, port triggering, MAC address filtering, access control, and WiFi Multimedia (WMM) for quality-of-service prioritization.

Management and Setup

Manage the G3100 through the My Fios app, the built-in web interface, or TR-069 remote management. The app lets you monitor connected devices, run speed tests, adjust WiFi settings, and set up parental controls from your phone. For a full walkthrough covering activation, WiFi setup, password changes, and fixes for blinking lights and connection drops, see our Verizon Fios G3100 Setup Guide.

Stop Renting Your Fios Router

Verizon charges a monthly fee to rent its router on many Fios plans, often around $18 per month, which can top $200 a year for equipment you could own. Some newer plans bundle the router, so check your bill to see what you are paying. If you are renting, this renewed G3100 typically pays for itself in under six months. If your current router is aging or dropping connections, our guide on how long modems and routers last covers the warning signs.

Verizon Fios G3100 Frequently Asked Questions

Is the G3100 compatible with Verizon Fios?

Yes. The G3100 is designed for Verizon Fios and was supplied by Verizon itself for Fios plans, so it activates smoothly in most areas. Confirm your specific plan with Verizon if you are unsure.

Is the G3100 a modem or a router?

The G3100 is a router. On Fios, the fiber connection terminates at your Verizon ONT, and the G3100 connects to that ONT by Ethernet or coax to distribute internet through your home.

Should I connect the G3100 to my ONT with Ethernet or coax?

Use Ethernet if your plan is faster than 100 Mbps. The G3100's Ethernet WAN supports Gigabit speeds, while its MoCA WAN over coax is limited to 100 Mbps. The MoCA 2.5 LAN side is separate and runs up to 2500 Mbps for in-home coax networking.

What is MoCA 2.5 and why does it matter?
