Verizon Fios G3100 Router Setup Guide: Activate, Install, Change WiFi & Bridge Mode
  • The Verizon Fios G3100 is a tri-band WiFi 6 router that connects via coax or Ethernet to your Verizon ONT. Setup takes about 15 minutes, and activation happens automatically through your web browser after connecting the hardware.
  • You can change your WiFi name (SSID) and password through the router's admin panel at 192.168.1.1 or through the My Verizon app. You should change both from the factory defaults as soon as possible to secure your network.
  • The G3100 does not have a dedicated bridge mode toggle, but you can configure IP Passthrough or disable its routing features manually to use your own third-party router. If you have Fios TV, keep the G3100 active for MoCA connectivity to your set-top boxes.

The Verizon Fios Home Router G3100 is a tri-band WiFi 6 router designed for Verizon's fiber optic internet service. It supports connections over coaxial cable, Ethernet, and WiFi, and it is compatible with Verizon's Fios Extender (E3200) for whole-home mesh coverage. Whether you are setting up a brand-new Fios connection or replacing an older Verizon router, this guide walks you through every step from unboxing to advanced configuration.

How to Install the Verizon Fios G3100 Router

What Is in the Box

The G3100 package includes the router itself, a white power adapter, a three-meter Ethernet cable, and a quick-start insert. You will also need the coaxial cable already installed in your home by Verizon (connected to your ONT), or an Ethernet cable if your ONT has an active Ethernet output.

Step-by-Step Hardware Installation

Step 1: If you are replacing an older router, unplug the power cord and disconnect the coaxial and/or Ethernet cables from your old router first.

Step 2: Locate the coaxial cable coming from your Verizon ONT (the box installed by Verizon, usually in your basement, garage, or utility closet). Connect it to the Coax WAN port on the back of the G3100.

Step 3: If your ONT has an active Ethernet output (common for Gigabit plans), connect an Ethernet cable from the ONT's Ethernet port to the Ethernet WAN port on the G3100 instead of, or in addition to, the coax connection.

Step 4: Plug the power adapter into the G3100 and connect it to a wall outlet. The front LED will begin blinking white, which means the router is booting up.

Step 5: Wait approximately two to three minutes. When the front LED turns solid white, the router is online and connected to the internet.

Placement Tip: Position the G3100 in a central, elevated location in your home for best WiFi coverage. Avoid placing it inside cabinets, behind TVs, or near microwaves and cordless phones, which can interfere with the wireless signal.

How to Activate the Verizon Fios G3100

The G3100 is designed to be plug-and-play. In most cases, activation happens automatically once the router connects to the Verizon network. However, if you are a new customer or the auto-activation does not trigger, follow these steps:

Step 1: Connect a computer or phone to the G3100. You can use WiFi (the default network name and password are printed on the label on the back of the router) or connect directly with the included Ethernet cable.

Step 2: Open a web browser and go to mynetworksettings.com. You can also type 192.168.1.1 into the address bar. If you see a security warning about the connection not being private, click Advanced, then click Proceed to 192.168.1.1.

Step 3: The Easy Setup Wizard should appear automatically the first time. If it does, follow the on-screen prompts. You will be asked to log in with the Admin Password printed on the label on the back of the router (this is different from the WiFi password).

Step 4: If prompted for activation, enter your Verizon account number or phone number and your billing zip code. The system will verify your account and associate the router with your Fios service.

Step 5: Once activation completes, you can personalize your WiFi network name and password through the wizard, or do it later from the settings panel.

Not Seeing the Activation Prompt? Clear your browser cache or try a different browser. Make sure you are connected to the G3100's network (not mobile data). You can also try the My Verizon app on your phone to complete activation.

How to Change the WiFi Password and SSID (Network Name) on the G3100

Changing your WiFi name and password from the factory defaults is one of the most important steps you can take to secure your home network. The default credentials are printed on a label on the back of the router, which means anyone who can see the label can access your network.

Method 1: Through the Router Admin Panel

Step 1: Connect a device to the G3100 via WiFi or Ethernet.

Step 2: Open a web browser and go to 192.168.1.1 (or mynetworksettings.com).

Step 3: Log in using the username admin and the Admin Password from the label on the back of the router.

Step 4: In the left-hand menu, click Wi-Fi. Then click Basic Settings in the top menu.

Step 5: In the SSID field, delete the current network name and type your new preferred name.

Step 6: In the Password field, enter your new WiFi password. Make sure the security type is set to WPA2 (or WPA2/WPA3 if available).

Step 7: Click Apply Changes to save.

After saving, any devices currently connected via WiFi will be disconnected. You will need to reconnect each device using the new network name and password.

Method 2: Through the My Verizon App

Step 1: Download and open the My Verizon app on your phone.

Step 2: Log in with your Verizon account credentials.

Step 3: Navigate to Internet or My Network.

Step 4: Select the network you want to edit and tap Manage.

Step 5: Enter your new WiFi name and/or password, then tap Save Changes.

Strong Password Tip: Use at least 12 characters with a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using personal information like your name, address, or birthday.

How to Set Up Bridge Mode on the Verizon Fios G3100

Bridge mode allows you to use your own third-party router (such as an ASUS, Netgear, or TP-Link router) to handle all of your network's routing, firewall, and WiFi duties while the G3100 simply passes the internet connection through.

Important: The G3100 Does Not Have a One-Click Bridge Mode

Unlike some other routers, the Verizon G3100 does not have a simple toggle to switch into bridge mode. Instead, you need to manually configure it by either enabling IP Passthrough or by disabling its DHCP server and changing its LAN IP address. The method you choose depends on whether or not you also have Fios TV service.

If You Do NOT Have Fios TV (Internet Only)

This is the simplest scenario. You can bypass the G3100 entirely by connecting your own router directly to the ONT via Ethernet.

Step 1: Connect an Ethernet cable from your ONT's Ethernet port directly to the WAN port on your third-party router.

Step 2: Power on your third-party router and follow its setup instructions.

Step 3: Return the G3100 to Verizon if you are renting it, or store it as a backup.

If your ONT only has a coax output and no active Ethernet, you may need to call Verizon and ask them to enable the Ethernet port on your ONT.

If You Have Fios TV (TV + Internet)

The G3100 uses MoCA (Multimedia over Coax Alliance) to communicate with Fios TV set-top boxes. If you remove the G3100 completely, your TV guide, Video on Demand (VOD), and voice remote features will stop working. Here is how to use your own router while keeping Fios TV functional:

Step 1: Connect the ONT to your third-party router via Ethernet (ONT Ethernet port to your router's WAN port). This router will handle your internet.

Step 2: Connect a LAN port on your third-party router to the Ethernet WAN port on the G3100 using an Ethernet cable.

Step 3: Log in to the G3100 admin panel at 192.168.1.1.

Step 4: Navigate to Advanced, then Network Settings, then IPv4 Address Distribution.

Step 5: Change the DHCP start address (for example, change it to start at 192.168.1.3), then click Apply.

Step 6: Disable the IPv4 Address Distribution (DHCP server) and click Apply.

Step 7: Go to Network Connections, select Network (Home/Office), click Settings, and change the G3100's IP address to something like 192.168.1.2 (so it does not conflict with your main router). Click Save Changes.

Step 8: Disable the G3100's WiFi radios to avoid interference. Navigate to Wi-Fi, then Basic Settings, and turn off all wireless bands.

Step 9: Reboot your Fios TV set-top boxes. They should pull IP addresses from your main router and continue to function normally for TV guide, VOD, and remote features via the G3100's MoCA connection.

Warning: This configuration results in a double NAT setup, which is generally fine for everyday browsing, streaming, and gaming. However, it can cause issues with hosting servers, some VPN configurations, or peer-to-peer applications. If you experience problems, you may need to set up port forwarding rules on both routers.

Alternative: IP Passthrough Method

Some G3100 firmware versions support IP Passthrough, which passes your public IP address directly to a connected device (your third-party router) without double NAT.

Step 1: Log in to the G3100 at 192.168.1.1.

Step 2: Navigate to Advanced Settings, then Network Settings, then Broadband Connection.

Step 3: Look for an option labeled IP Passthrough, DHCP Passthrough, or DMZ. If available, enable it and assign it to the MAC address of your third-party router.

Step 4: Save changes and reboot both routers. Your third-party router should now receive the public IP address directly from Verizon.

Note: Not all firmware versions display this option in the same location. If you do not see IP Passthrough in your settings, your firmware may not support it, and the DHCP disable method described above is your best alternative.

Troubleshooting Common Verizon Fios G3100 Issues

1. Intermittent WiFi Drops or Disconnections

This is one of the most commonly reported problems with the G3100. Devices lose WiFi connection randomly and then reconnect after a few seconds or minutes.

Fix:

  • Reboot the router by unplugging the power cord, waiting 30 seconds, and plugging it back in.
  • Log in to the admin panel and check if a firmware update is available. Verizon pushes firmware updates automatically, but you can verify the current version under System then System Status.
  • Try disabling IPv6 on the router. Go to Advanced, then Network Settings, and disable IPv6. This has resolved WiFi instability for many G3100 users, particularly after the 3.1.0.13 firmware update.
  • Change the WiFi channel manually. Go to Wi-Fi, then Advanced Settings, and select a specific channel instead of Auto. Channels 1, 6, or 11 are best for the 2.4 GHz band.

2. Slow Internet Speeds (Not Getting Speeds You Pay For)

Some users report significantly slower speeds than their plan provides, particularly on upload.

Fix:

  • Test with a wired Ethernet connection first to rule out WiFi as the cause. Connect a computer directly to one of the G3100's LAN ports and run a speed test at speedtest.net.
  • Disconnect the coaxial cable from the back of the router and test again. Noise on the coax line (from old splitters, damaged cables, or Fios TV set-top boxes) can drag down speeds.
  • Disable all WiFi radios temporarily and test only the wired connection to isolate the issue.
  • Reset the router to factory defaults by pressing and holding the red reset button on the back with a paperclip for 15 seconds. Reconfigure your settings afterward.
  • If wired speeds are also slow, contact Verizon support. The issue may be at the ONT or on the network side.

3. Cannot Access the Router Admin Page (192.168.1.1 Not Loading)

The login page does not load, shows a blank screen, or the page hangs after you enter your password.

Fix:

  • Make sure you are connected to the G3100's network, not mobile data or a different WiFi network.
  • Try a different web browser. Chrome, Firefox, and Edge all work, but some browser extensions (especially ad blockers or security extensions) can interfere.
  • If you see a "connection not private" warning, click Advanced, then Proceed to 192.168.1.1. This is normal and safe since you are connecting to your own router.
  • Temporarily disable your antivirus software, as some security programs block the router's self-signed certificate.
  • If the page loads but freezes after entering the password, try connecting via Ethernet instead of WiFi, and reboot the router before attempting to log in again.

4. Default WiFi Password Not Working

You enter the password from the label on the back of the router, but devices will not connect.

Fix:

  • Double-check that you are using the WiFi password, not the Admin password. They are different and are both printed on the same label.
  • Make sure you are entering the password with the correct capitalization. WiFi passwords are case-sensitive.
  • If someone previously changed the password and you do not know the current one, perform a factory reset by pressing and holding the red reset button on the back of the router with a paperclip for 15 seconds. This restores all settings to the defaults printed on the label.

5. Front LED Is Yellow (No Internet Connection)

A solid or blinking yellow LED on the front of the G3100 means the router does not have an internet connection.

Fix:

  • Check that the coaxial cable and/or Ethernet cable between the ONT and the G3100 are firmly connected at both ends.
  • Check the ONT itself. If the ONT's power light is off or its broadband light is red, the issue is upstream from the router. Make sure the ONT is powered on and that the battery backup (if present) is not depleted.
  • Reboot both the ONT and the G3100. Unplug the ONT first, wait 30 seconds, plug it back in, and wait for it to fully boot (about two minutes). Then reboot the G3100.
  • If the yellow LED persists after rebooting both devices, contact Verizon support. The issue is likely on Verizon's network side or the ONT needs to be reprovisioned.

6. Devices Cannot Find the WiFi Network (SSID Not Visible)

Your phone, laptop, or other device does not show the G3100's WiFi network in its list of available networks.

Fix:

  • Make sure WiFi is enabled on the router. Log in to 192.168.1.1, go to Wi-Fi, then Basic Settings, and confirm all bands are turned on.
  • Check that SSID broadcast is not hidden. On the same Wi-Fi settings page, make sure the "Hide SSID" or "Broadcast SSID" option is set to broadcast (visible).
  • Restart the WiFi adapter on your device. On most devices, toggle WiFi off and back on, or toggle airplane mode on and off.
  • If only older devices cannot see the network, they may not support 5 GHz WiFi. Make sure the 2.4 GHz band is enabled in the router settings.

7. Printer or Smart Home Devices Cannot Connect

Printers, smart plugs, cameras, and other IoT devices sometimes have trouble obtaining an IP address from the G3100.

Fix:

  • Most IoT devices only support the 2.4 GHz band. Make sure 2.4 GHz WiFi is enabled on the router.
  • If the device's host name contains special characters (such as apostrophes, periods, or underscores), the G3100's DHCP server may reject it. Rename the device using only letters, numbers, and dashes.
  • Try toggling the 2.4 GHz band off and back on from the router settings to force a refresh of the DHCP lease table.
  • Reboot both the router and the device that is having trouble connecting.

Frequently Asked Questions

How do I log in to my Verizon Fios G3100 router?

Connect a device to the G3100 via WiFi or Ethernet. Open a web browser and type 192.168.1.1 or mynetworksettings.com into the address bar. Log in with the username admin and the Admin Password printed on the label on the back of the router. If you changed the password and cannot remember it, a factory reset will restore the default login credentials.

How do I reset my Verizon Fios G3100 to factory settings?

Locate the small red reset button on the back of the router. Using a paperclip or similar pointed object, press and hold the reset button for 15 seconds while the router is powered on. The LED will flash, and the router will reboot. After it restarts, all settings will be restored to the factory defaults printed on the label. You will need to reconnect all your devices using the default WiFi name and password.

Can I use my own router with Verizon Fios instead of the G3100?

Yes. If you have an internet-only plan (no Fios TV), you can connect any third-party router directly to your ONT's Ethernet port and skip the G3100 entirely. If you have Fios TV, you will need to keep the G3100 connected to provide MoCA service to your set-top boxes, but you can disable its WiFi and DHCP and let your own router handle the network. You may need to call Verizon to have the ONT's Ethernet port activated if it is not already enabled.

What do the LED lights on the Verizon G3100 mean?

A solid white LED means the router is powered on and connected to the internet normally. Blinking white means the router is booting up. Solid or blinking yellow means there is no internet connection. Slowly blinking blue means the router is in WPS pairing mode, waiting for a device to connect. Solid blue means a WPS pairing was successful. Slowly blinking red indicates a WPS pairing error.

Does the Verizon Fios G3100 support WiFi 6?

Yes. The G3100 is a tri-band WiFi 6 (802.11ax) router. It operates on one 2.4 GHz band and two separate 5 GHz bands. WiFi 6 devices connected to the G3100 will benefit from faster speeds, better performance in congested environments, and improved battery efficiency on mobile devices. Older devices that do not support WiFi 6 will still connect using older WiFi standards (such as WiFi 5 or WiFi 4) and work normally.

How do I extend the WiFi range of my Verizon Fios G3100?

Verizon's recommended solution is the Fios Extender (E3200), which pairs with the G3100 to create a mesh network using Verizon's Self-Organizing Network (SON) technology. You can pair the extender wirelessly by pressing the buttons on both devices for two seconds until they blink blue, or by connecting the extender to a coax outlet in an area with weak coverage. Third-party mesh systems and WiFi extenders also work, though they will not use Verizon's SON feature.

How many devices can the Verizon Fios G3100 support?

The G3100 can technically support up to 254 connected devices, but Verizon recommends no more than 132 connections for stable performance. In practice, most households with 20 to 50 connected devices (phones, laptops, smart TVs, smart home gadgets) will have no issues. As the number of active devices increases, available bandwidth per device decreases, so extremely device-heavy homes may benefit from adding an extender or upgrading to a higher-speed plan.
