Speed test is available in some versions of the Nokia WiFi mobile app (depending on your service provider).
Speed test measures the speed between your root WiFi point and a test server (WAN port speed).
Swipe down to the Internet Speed section in the home screen of the Nokia WiFi mobile app and tap New speed test. The app begins the speed test. The speed test result is displayed with download and upload speed in Mbps.
To perform another speed test, tap Start Test.
