Run a gFiber Internet Speed Test

Measure your network bandwidth using the gFiber App or a wired connection, understand your test results, and fix slow speeds.

To measure your network speed, open the gFiber App, select Network, and tap Run a speed test. For multi-gig connections like Core 1 Gig, Home 3 Gig, 5 Gig, or Edge 8 Gig, connect your computer directly to your router’s 10G LAN port using an Ethernet cable and run the test at gfiber.com/speedtest.

Test speed with the gFiber App

The gFiber App measures bandwidth coming into your home and wireless performance on individual devices. Before testing, download and open the gFiber App for Android or iOS.

In the gFiber App, tap Network in the bottom menu.
In the Network screen, tap Run a speed test.
Select your test type:
- Your router: Measures speed directly from the gFiber network to your router (wired speed to your home).
  
  Testing speed directly to your router provides the most accurate reflection of your overall gFiber service performance.
- This device: Measures speed between your router and your current mobile device (Wi-Fi speed to device).

Your screen will display download and upload speeds. Wi-Fi device tests will also display ping (latency) and jitter metrics.

Test speed using a wired connection

A wired Ethernet connection provides the most accurate reading for multi-gig Lifestyle Internet Products like Core 1 Gig, Home 3 Gig, 5 Gig, or Edge 8 Gig, as Wi-Fi hardware and web browsers may cap maximum bandwidth.

Preparation checklist

Connect your computer directly to a LAN port on your gFiber router using a Cat 6 or higher Ethernet cable. If using a Wi-Fi 6E Router or Multi-Gig Router, plug into the silver 10G LAN port.
Connect your computer to its power adapter.
Update your operating system and web browser to the latest version.
Open a private or incognito browser window to bypass extensions.
Close all open applications, background downloads, and extra browser tabs.

Run a wired speed test

Open a browser and go to gfiber.com/speedtest.
Select Go to start the speed test.
Alternatively, open the Ookla Speedtest desktop app on Windows or macOS for multi-gig measurements.

The test will report your direct download speed, upload speed, and ping time in milliseconds.

Understand speed test results

Metric	What it measures	Ideal range
Download speed	Rate at which data transfers from the internet to your device (streaming, downloading files).	Matches your gFiber plan (e.g., up to 1000 Mbps for 1 Gig) over a direct Ethernet cable. Over Wi-Fi, speed test results are limited by Wi-Fi standards and distance from the router, typically maxing out around 300–800 Mbps regardless of gigabit capabilities.
Upload speed	Rate at which data transfers from your device to the internet (video calls, file uploads).	Matches your gFiber plan (symmetrical speed) over a direct Ethernet cable. Over Wi-Fi, speed test results are limited by Wi-Fi standards and distance from the router, typically maxing out around 300–800 Mbps regardless of gigabit capabilities.
Ping (Latency)	Delay in milliseconds (ms) for data to travel to a server and back.	Lower is better (typically under 15 ms on fiber).
Jitter	Variance in latency over time.	Lower is better (typically under 3 ms).

Troubleshoot slow internet speeds

If your speed test results show lower bandwidth than expected, compare your router test results with your device test results to identify the cause.

Check router speed: If the "Speed to your home" test result in the gFiber App is lower than your subscribed speed, restart your gFiber router. In the gFiber App, select Network, tap Restart Router, and wait 3 minutes before testing again. Restarting your router will temporarily disconnect all wired and Wi-Fi devices from the internet for up to 3 minutes.
Check device Wi-Fi speed: If the "Speed to your home" test is fast but the "Speed to your device" test is slow, your Wi-Fi environment is restricting bandwidth. Move closer to your router or extender, clear physical obstructions, or connect high-bandwidth devices via Ethernet.
