The app distinguishes router-to-internet performance from device-to-internet and device-to-router tests. Comparing these helps separate a Wi-Fi limitation from the internet connection itself. Menu names may vary with the app version.
If device-to-router performance is much lower, move closer to the router and test again. Pause large downloads, repeat measurements and record the time, device and location. Network load changes, so one slow result alone does not prove a fault.
