The university has two Wi-Fi networks: LUWA and eduroam.

Leiden University Wireless Access netwerk (LUWA) 

The Leiden University Wireless Access (LUWA) network is intended for temporary access to wireless internet. Data sent via the LUWA network is not encrypted. You also need to re-log in every five days.​

Eduroam netwerk

With eduroam, you don't need to re-log in. It's also safer as all data is encrypted. Eduroam allows you to access Wi-Fi in almost all universities and universities of applied sciences in the Netherlands, Europe and further afield. Choose your device from the table below to open the corresponding manual.


PLEASE NOTE: different username

With eduroam you use your regular ULCN user name - i.e. your student number - followed by @leidenuniv.nl (this may look like an email address but it is not). With the addition @leidenuniv.nl you can automatically connect to eduroam from numerous educational institutions worldwide. Example: if your ULCN name is 's1234567', use 's1234567@leidenuniv.nl' as your identity/user name.  

Safe use of public Wi-Fi networks: eduVPN

When using public Wi-Fi networks, for example in a train or café, your personal data is often not secure. eduVPN offers protection against prying eyes and enables you to securely access protected services from outside Leiden University's network.
