Depending on the subscription chosen by the landlord, you can choose a maximum amount of devices/sessions to connect simultaneously.
In My Dashboard, you can see how many simultaneous sessions you can connect to.
When using the secured Wi-Fi SMARTEYE-Secure it is possible that 1 device uses up to 2 temporary sessions due to technical reasons. Therefore check whether you have sufficient reserve sessions left when your device appears to lose its Wi-Fi connection regularly.
Connecting more devices than the given maximum?
It is not possible to connect more devices simultaneously than the maximum amount given. You can log off other devices first and thus release sessions in order to connect new devices.
