Internet Speed Test & Broadband Tools

Test your real download speed and compare it to FCC broadband benchmarks. No signup required.

Download Speed Test

Test Your Download Speed

Our speed test downloads data to your browser and measures real throughput. For the most accurate results, use a wired ethernet connection and close other applications.

Test your internet download speed

Methodology

How the Speed Test Works

1. Download Test Data

We download a 5 MB test file from our CDN to your browser, measuring the total transfer time.

2. Multiple Iterations

The test runs 3 times and averages the results, reducing the impact of momentary fluctuations.

3. Compare to Benchmarks

Results are compared against the FCC broadband benchmark (100 Mbps) and rated from Excellent to Very Slow.

Tips for Accurate Results

  • 01Use a wired connection. Ethernet eliminates Wi-Fi overhead and shows your true ISP speed.
  • 02Close other applications. Background downloads, streaming, and cloud sync consume bandwidth.
  • 03Test at different times. Peak hours (7-11 PM) typically show slower speeds on cable connections.
  • 04Restart your modem. A quick reboot can resolve temporary performance issues.
  • 05Try multiple tests. Use our test, Fast.com, and Speedtest.net to compare results.

FAQ

Speed Test FAQ

How accurate is this speed test?

Our speed test measures real download throughput by transferring data to your browser and timing how fast it arrives. Results are most accurate on a wired ethernet connection with other applications closed. Wi-Fi testing will show lower speeds due to wireless overhead. We run multiple iterations and average the results to reduce variance.

Why is my speed test result different from other sites?

Speed test results vary because different services use different test servers, methodologies, and data sizes. Our test uses multi-iteration averaging and measures from your browser to our CDN. Ookla Speedtest connects to a nearby ISP-peered server. Netflix Fast.com tests from Netflix servers. No single test is definitive — run several for a complete picture.

What is a good download speed?

The FCC defines broadband as 100 Mbps download. For a single user streaming in 4K, 25 Mbps is sufficient. A household of 4 with multiple streamers and remote workers should aim for 200-500 Mbps. Gigabit (1,000 Mbps) plans provide headroom for heavy use but most activities do not require it.

Why is my Wi-Fi slower than my internet plan?

Your router is likely the bottleneck. Wi-Fi 5 routers max out around 400-800 Mbps in practice. Walls, distance, and interference further reduce speed. Test with an ethernet cable plugged directly into your modem — if wired speed matches your plan, the issue is your router or Wi-Fi environment, not your ISP.

How often should I test my speed?

Test at different times of day to understand peak vs. off-peak performance. Cable internet often slows 20-40% during evening hours (7-11 PM). If you consistently get less than 80% of your plan speed on a wired connection, contact your ISP. Speed tests after a modem restart can also reveal equipment issues.
