Your Wi-Fi speed test is lying to you about the problem that matters most
Most people run a speed test the same way you check weight on a scale, as if one number tells the whole story. The number tends to look good, but it is a really narrow way to judge your connection quality. That Wi-Fi speed test has almost nothing to do with how a connection works in real conditions.
