Your WiFi Speed Test Results Mean Less Than You Think

You run a speed test and it says 250 Mbps download. Your ISP plan says "up to 300 Mbps." So you are getting 83% of what you pay for. Is that good? It depends on what you are actually testing. Most people interpret speed test results as "the speed of my internet." What they are actually measuring is "the speed between my device and a specific server, at this moment, through my WiFi, my router, my modem, my ISP's network, and the peering between my ISP and the test server." Every link in that chain is a potential bottleneck. What speed tests actually measure Download speed. How fast you can pull data from a server. Measured by downloading a large file (or multiple files) and calculating the throughput. Reported in Mbps (megabits per second). Upload speed. How fast you can push data to a server. Usually much slower than download for residential connections (asymmetric). Important for video calls, file uploads, and streaming. Latency (ping). The round-trip time for a small packet to reach
