A speed test measures one path at one moment — not your plan. A result below your subscribed speed usually has an explanation closer to the device than the network.
The common gaps
- Testing over WiFi — walls, distance and interference all take a cut
- Device limits — older laptops and phones top out below modern plan speeds
- A nearby test server flattering the result, while your real workload talks to a distant one
- Other users and devices on the LAN mid-test
- A busy server on the other end of the test
How to test fairly
Plug directly into the router with a cable, test from one device with everything else quiet, and run a few tests at different times of day. Still off after that? Contact support and we will investigate.
