This free Google Fiber speed test verifies your Google Fiber connection — download speed, upload speed, ping, and jitter — in under a minute.

Google Fiber plans include 1 Gig, 2 Gig, and up to 8 Gig in select cities, all with symmetric uploads. To see full gigabit speeds you need a wired connection: most Wi-Fi setups top out well below 1 Gbps in real-world conditions.

Why doesn’t my Wi-Fi hit 1 Gig?

Wi-Fi rarely delivers full gigabit speeds. Wi-Fi 6 devices in ideal conditions reach 600–900 Mbps; older Wi-Fi 5 devices often max out around 400 Mbps. This is a Wi-Fi limitation, not a Google Fiber problem.

To verify your full plan speed, connect a computer with a gigabit (or multi-gig for 2/8 Gig plans) Ethernet port directly to the Fiber Jack or router and test again.

Getting the most from Google Fiber

Use the Google Fiber app to check your network and manage the included Wi-Fi 6 router. For 2 Gig and 8 Gig plans, you need a 2.5 GbE or 10 GbE wired adapter to see the full speed — standard gigabit Ethernet caps at ~940 Mbps.

If wired speeds are far below your plan, check the Fiber Jack’s indicator light and restart the network box before contacting support.

How to run an accurate speed test

For the most accurate result, connect your computer directly to your router with an Ethernet cable if possible. If you must use Wi-Fi, stand close to the router and disconnect other devices during the test.

Close streaming apps, cloud backups, and other browser tabs before clicking Start. Run the test 2–3 times at different times of day — speeds often dip during evening peak hours (7–11 PM) when many households are online.

Understanding your results

Download speed (Mbps) controls how fast you can stream, browse, and download files. Upload speed (Mbps) affects video calls, live streaming, and cloud backups. Ping (ms) measures responsiveness — under 50 ms is good for gaming and calls. Jitter (ms) measures consistency — lower is better, especially for voice and video.

Compare your download result to your plan’s advertised speed. Most providers advertise “up to” speeds, so a result within about 20% of the advertised rate is normal.

Frequently Asked Questions

On a wired gigabit-Ethernet connection, 900+ Mbps on the 1 Gig plan is excellent. Wi-Fi results of 400–800 Mbps are normal and limited by wireless technology, not your fiber line.
