Get Connect To Radius Wifi old version APK for Android
Connectez votre téléviseur à votre Android Wifi Enterprise (WPA EAP)
We wrote this app to connect our Nexus Player to the company wifi. (WPA EAP / IEEE 802.1X / WPA Enterprise / Cisco Radius Network)
We guess it could be useful for developers, companies and schools using an Android TV device in an enterprise wifi.
At this time the Nexus Player Settings in Android 5 do not show any GUI to connect to Enterprise Wifis. Nevertheless the functionality is inside the device and since API 18 can be accessed in any Android App.
It works fine for us with Identity, Password, PEAP and MSCHAPv2. (Any other configurations remain untested.)
