How to reliably check your internet speed

Having a fast internet connection is essential, especially when streaming content or playing online games. However, knowing whether you’re truly getting the speed you pay for is just as important. Many users fail to test their internet connection correctly, leading to inaccurate results that can obscure real issues or cause unnecessary concern.

Use a wired connection for accurate results

The most reliable way to test your internet speed is by connecting your computer directly to the router using an Ethernet cable. Wi-Fi signals are susceptible to interference from walls, other devices, and even microwaves, which can drastically alter your test results. Only with a wired connection can you eliminate these variables and get a true measure of your connection’s performance.

Close all apps and limit device usage

Before running a speed test, it’s essential to close all applications that use the internet, including browser tabs, streaming platforms, or software running in the background. Additionally, make sure no other devices—like smart TVs, smartphones, or tablets—are connected to the network. This ensures that the test reflects only your device’s internet usage, giving you more accurate data.

Choose a trustworthy testing tool

Using a reliable website like fast.com allows you to select your internet provider and the nearest server. This minimizes external factors and provides a clearer picture of your actual speed. The test typically takes about 15 seconds, evaluating both upload and download rates, and even shows your ping—a critical measure of latency for online gaming or video calls.
