Android Disconnects from WiFi

Problem

Android keeps disconnecting and/or reverts to EUI-WiFi instead.

Solution 

1. Android will connect to the wireless service only when it is available and required - so if you find at times you don't have a connection, it maybe because Android has decided it has no use for it at the time.
2. Android also tries to use the best available wireless source in terms of signal thus may revert to EUI-WiFi (above all if it has been configured to automatically connect to it whenever available) unless manually forced to stick to eduroam.
