If your WiFi connection drops off you will need to re-connect by logging on again (usual University username and password). It is a common measure for no passwords to be stored on any device. Your own laptop may store your username but you will have to enter your password as required.
In order to protect your own hardware and files this is an important security measure. I appreciate there is a small inconvenience in having to do this but it is not an unusual requirement and in terms of your own security it is a useful deterrent
