How to Use Your Own Router with Google Fiber (1G, 2G & 5G Plans)

Updated 2026-10-09 • By Elena Rostova, CCNP (Network Infrastructure Architect)

On all modern Google Fiber 1G, 2G, 5G, and 8G plans, you can connect any third-party router directly to the wall-mounted Google Fiber Jack (ONT) using a Cat6/Cat6a Ethernet cable and standard untagged Dynamic DHCP—no VLAN ID 2 or 802.1p QoS tagging is required. Alternatively, you can place the Google Fiber Wi-Fi 6E Router (GFEX310/GRAX210T) into Bridge Mode at fiber.google.com.

1. Direct Connection to the Google Fiber Jack (1G, 2G, 5G & 8G ONTs)

Google Fiber (GFiber) is one of the most third-party-router-friendly ISPs in the United States. The small white or silver box mounted on your interior wall is the Google Fiber Jack, which is a full Optical Network Terminal (ONT). Depending on your speed tier, you will have one of two Fiber Jack generations:

• 1 Gig Fiber Jack (Models GFLT110, GFLT300, GOGP220C): Outputs a standard 1GbE RJ45 handoff. Note that older GFLT110 jacks can be powered either by a Micro-USB / USB-C 5V wall adapter OR by 802.3af PoE over the Ethernet cable. Make sure the Fiber Jack's USB power cord is plugged into an AC outlet before removing a PoE-supplying Google router.
• Multi-Gig XGS-PON Fiber Jack (Models GFOJ100, GoXP330C for 2G / 5G / 8G): Features a dedicated barrel DC power adapter and a 10GbE silver RJ45 port that auto-negotiates at 1GbE, 2.5GbE, 5GbE, or 10GbE.

Simply unplug the Ethernet cable from the Google-supplied router, connect it directly to the WAN port on your own router, and reboot the Fiber Jack for 30 seconds.

2. Why You No Longer Need VLAN ID 2 or 802.1p Priority Tagging

If you search older networking forums from 2015–2020, you will see complex guides warning that replacing the black GFRG200 / GFRG210 Google Fiber Network Box requires a managed switch or custom scripts setting 802.1Q VLAN ID 2 and 802.1p CoS Priority 3 on the WAN interface (otherwise upload speeds were throttled to 10 Mbps).

Do not enable VLAN ID 2 on a modern Google Fiber account. Beginning with the rollout of the Google Wifi / Nest Wifi pucks and the Wi-Fi 6E Multi-Gig router, Google migrated its entire residential OLT architecture to standard untagged Ethernet frames:

• WAN Connection Type: Automatic IP / Dynamic IP (DHCP).
• 802.1Q VLAN Tagging: Disabled / Untagged (enabling VLAN 2 on a migrated account will cause a total WAN DHCP failure!).
• IPv6 Configuration: Enable Native / DHCPv6 with Prefix Delegation enabled and prefix length set to 56 (Google Fiber delegates a static-style 2605:a601:...::/56 block to every residential customer).

3. How to Enable Bridge Mode on the Google Fiber Wi-Fi 6E Router (GFEX310)

What if you have an older Technicolor GFRG300 (where the SFP+ fiber transceiver plugs directly into the router chassis instead of a separate wall Fiber Jack), or you simply prefer to leave the Google Fiber Wi-Fi 6E Router (`GFEX310` / `GRAX210T`) physically mounted on the wall as a media converter in front of your own router?

Because the Google Fiber Wi-Fi 6E router is cloud-managed, you toggle Bridge Mode from your Google Fiber account portal rather than a local 192.168.1.1 page:

• Step 1: Sign in at https://fiber.google.com (or open the Google Fiber mobile app) using the Google account associated with your service.
• Step 2: Select Network from the left navigation menu, then click Edit Network Settings → Advanced Network Settings.
• Step 3: Check or toggle Enable Bridge Mode and click Save. The GFEX310 will reboot for 2 minutes, turn off its internal WiFi radios and DHCP server, and pass the public WAN IP directly through its silver 10G LAN port to your third-party router.

4. Selecting Hardware for 2 Gig, 5 Gig, and 8 Gig Symmetrical Tiers

When connecting your own router directly to the 10GbE Multi-Gig Fiber Jack (GoXP330C), make sure your router's port architecture matches your subscribed symmetrical speed tier:

• For 1 Gig ($70/mo): Any modern WiFi 6/6E/7 router with a 1GbE or 2.5GbE WAN port (such as an ASUS RT-AX86U Pro, GL.iNet Flint 2, or Ubiquiti UniFi Express / UCG-Ultra) will easily sustain 940/940 Mbps with sub-2 ms ping.
• For 2 Gig ($100/mo): Avoid routers that have a single 2.5GbE port (which caps all wired LAN ports to 1GbE). Choose a router with dual 2.5GbE ports (1x 2.5G WAN + 1x 2.5G LAN), such as the Ubiquiti Cloud Gateway Max (UCG-Max), GL.iNet Flint 2 (GL-MT6000), or TP-Link Archer BE550 / GE800.
• For 5 Gig & 8 Gig ($125–$150/mo): Require a router with dual 10GbE RJ45 or SFP+ ports and hardware NAT offloading, such as the Ubiquiti Dream Machine Pro Max (UDM-Pro-Max), Cloud Gateway Fiber, ASUS RT-BE96U / GT-BE98 Pro, or MikroTik CCR2004.

Google Fiber Own-Router Installation Checklist

1. Verified the wall-mounted Google Fiber Jack (ONT) has its dedicated USB or DC barrel power adapter plugged into a working outlet.
2. Unplugged the Google-supplied router and connected a Cat6 or Cat6a patch cord directly from the Fiber Jack to your router's WAN port.
3. Confirmed 802.1Q VLAN Tagging (VLAN ID 2) is DISABLED on your router's WAN interface.
4. Configured WAN for Dynamic IP (DHCP) and enabled Native IPv6 (DHCPv6 with a /56 Prefix Delegation size).
5. Verified your router's WAN interface negotiated at 1000 Mbps, 2.5 Gbps, or 10 Gbps matching your Google Fiber plan.
6. Stored the Google-supplied router and mesh extenders safely in a box (or returned them to a GFiber Space) in case of future return.

Frequently Asked Questions

If I still have a black Google Fiber Network Box (GFRG200) requiring VLAN ID 2, how do I get rid of it?

Log into your account at fiber.google.com, open customer support chat, and request to switch your account to the 'Use Your Own Router' (BYOR) profile. Google Fiber support will remotely update your OLT port profile in under 5 minutes to remove the legacy VLAN 2 requirement so any standard router works directly on the Fiber Jack.

Why did the LED on my 1 Gig Google Fiber Jack turn off when I unplugged the Google router?

Older GFLT110 Fiber Jacks were often powered via 48V 802.3af Power over Ethernet (PoE) from the Google Network Box's WAN port. Either plug a standard 5V/2A Micro-USB phone charger into the bottom of the GFLT110 Fiber Jack, or insert a $15 Gigabit 802.3af PoE injector between the Fiber Jack and your new router.

Can I use the free Google Nest Wifi Pro pucks as wired access points behind my own router?

While you can set a single Google Nest Wifi Pro puck to Bridge Mode inside the Google Home app, Google's firmware disables wireless mesh networking between multiple Nest Wifi Pro units when the primary puck is placed in Bridge Mode. For multi-node wired backhaul behind a custom firewall, third-party APs (like Ubiquiti UniFi or TP-Link Deco in AP mode) work much better.

What if my home has the Technicolor GFRG300 where the fiber optic line plugs directly into the router with no wall Fiber Jack?

Early 2 Gig installations used the GFRG300 with an internal SFP+ optical stick instead of a separate wall ONT. You can either enable Bridge Mode at fiber.google.com, or contact Google Fiber support to schedule a free technician visit to replace the GFRG300 with a standalone 10GbE XGS-PON Fiber Jack (GoXP330C).
