WiFi Manager 3.0.6 by Kostya Vasilyev, Android 5.0.1. The Mbps numbers are all over the place from minute-to-minute.... same WAP - e.g. 6 Mbps one minute, 81Mbps a few minutes later..... maybe 400 some other time. Would the app be using the API of the same name? Is that degree of variation to be expected? Do the app's numbers reflect reality?
