When you check WiFi speed using WiFi speed tests, your client (usually a web browser) establishes multiple connections and either begins to send or receive chunks of data. But if you’re playing an online game, even a few extra milliseconds of delay can cause you to lose a match because your opponents will literary have more time to respond than you.ĭownload and upload speeds are self-explanatory measures that seldom tell the full story. If you’re just watching online videos on YouTube, you aren’t likely to notice high latencies because your web browser automatically pre-loads a portion of the video to deliver a smooth viewing experience. Latency is measured in milliseconds, and anything over 40-70ms is usually considered too high. Latency, or ping, is the time it takes a server to respond to a request sent by your web browser, a music streaming app, or operating system. Each of these test components affects the performance of your internet connection. Online WiFi speed tests usually measure latency, download speed, and upload speed.
