Google Fiber operates in a select but growing number of US cities including Kansas City, Austin, Nashville, Salt Lake City, Charlotte, and others. Every Google Fiber plan is symmetric fiber-to-the-home, with no data caps and straightforward pricing. The 1 Gig plan is the most common entry point, but the 2 Gig plan has become widely available in Google Fiber markets, and a 5 Gig plan is rolling out to select addresses. These multi-gig plans change router selection significantly — most consumer routers cannot route 2+ Gbps.
Google Fiber installs an ONT at your home and provides a Network Box gateway that connects to the ONT and handles Google Fiber authentication. The Network Box doubles as a Wi-Fi router, and for many homes it performs adequately on the 1 Gig plan. However, for customers who want more advanced controls, better Wi-Fi coverage, or are on the 2 Gig or 5 Gig plan, using your own router in passthrough mode is the right move.

Setting Up Passthrough Mode on Google Fiber's Network Box
Google Fiber's Network Box supports a passthrough mode called "DMZ" that forwards all traffic to a designated device — your own router. To enable it, log into the Network Box admin interface (typically at 192.168.86.1), navigate to the advanced network settings, and configure DMZ or IP passthrough pointing to your router's MAC address. Once set, your router receives Google Fiber's public IP and handles all routing, NAT, DHCP, and firewall functions. The Network Box stays online for ONT management and Google Fiber authentication but does not actively route your traffic.
One important hardware detail: Google Fiber's Network Box for 2 Gig and 5 Gig plans includes a 10G Ethernet port alongside standard 1G ports. When running your own router in passthrough mode on a multi-gig plan, you must cable your router to the Network Box's 10G port using Cat 6 or Cat 6A cable. Using a standard 1G port on the Network Box side caps your entire connection at under 940 Mbps, negating the multi-gig plan entirely.
Why Google Fiber 2 Gig Changes Everything
Most consumer router advice is written for homes with 1 Gbps or slower internet. Google Fiber's 2 Gig plan breaks those assumptions. A router that "supports gigabit" may use software NAT that tops out at 500 to 800 Mbps of actual routed throughput in real-world conditions. On a 2 Gig plan, a router that cannot hardware-accelerate NAT at 2+ Gbps will bottleneck your connection below what a slower, cheaper plan would deliver.
The ASUS ZenWiFi Pro ET12 and eero Max 7 are the two strongest consumer options for Google Fiber 2 Gig. Both use hardware NAT offloading capable of sustaining 2 Gbps+ routed throughput. The ET12's 10G WAN port connects directly to the Network Box's 10G LAN port, and wired clients on the ET12's 10G LAN port can hit close to 2 Gbps on a single TCP stream. Wireless clients, even on Wi-Fi 6E or Wi-Fi 7, will not reach 2 Gbps over the air — but multi-device aggregate throughput across many simultaneous streams benefits substantially from the extra headroom.
Google Fiber and Smart Home Integration
Because Google Fiber is a Google product, it naturally integrates well with Google Home and Nest devices. The default Network Box works with the Google Home app for basic monitoring. If you switch to your own router, you lose the Google Home integration for network management — but most third-party routers offer comparable or better device management through their own apps. The eero Max 7 is a notable exception: it integrates directly with the Amazon Alexa ecosystem rather than Google Home, which suits households already invested in Alexa-controlled smart home devices. For pure Google Home households, the Google Nest WiFi Pro is worth considering, though it lacks the multi-gig WAN hardware needed for Google Fiber 2 Gig.
The Firewalla Gold Plus takes a different approach: it is a network security and monitoring device that routes traffic and provides exceptional visibility into what every device on your network is doing. Paired with Wi-Fi access points and connected to the Network Box's 10G port, it delivers multi-gig routing with per-device traffic analytics, VPN server and client, ad blocking, and intrusion detection — capabilities no consumer mesh router matches.
Frequently Asked Questions
Does Google Fiber require their router?
No. Google Fiber provides a Network Box gateway but allows customers to use their own router in passthrough mode. You configure the Network Box to pass the public IP directly to your own router, which then handles all routing, NAT, and Wi-Fi. The Network Box continues to handle ONT communication and Google Fiber authentication in the background without interfering with your router's operation.
What speeds does Google Fiber's own router support?
Google Fiber's Network Box handles the 1 Gig plan adequately for most households. For the 2 Gig and 5 Gig plans, Google provides hardware with multi-gig ports. If you use your own router in passthrough mode on a 2 Gig or 5 Gig plan, ensure the cable from the Network Box to your router uses the 10G LAN port on the Network Box and is Cat 6 or Cat 6A.
Is a 2.5G WAN port enough for Google Fiber 2 Gig?
A 2.5G WAN port gives you significantly faster speeds than a 1G port on the 2 Gig plan, but caps throughput below 2000 Mbps. For full 2 Gig throughput on wired connections, a 10G WAN port is the right choice. Wireless clients cannot reach 2 Gbps over Wi-Fi regardless of WAN port speed — the benefit of 10G WAN shows up most clearly on wired clients with 2.5G or 10G network adapters.
Does Google Fiber have data caps?
No. Google Fiber does not impose monthly data caps on any residential plan. All plans — 1 Gig, 2 Gig, and 5 Gig — include unlimited data. This has been a consistent Google Fiber policy since launch and remains one of the service's defining advantages over cable competitors that impose 1.25 TB monthly limits.
