Wireless: Eduroam

The wireless network in our buildings is the international educational network Eduroam.

This is the standard Educational Roaming Network that you may already be used to. It provides secure wireless access using your ULCN account information not only at this University but in principle everywhere in the educational world. For details how to setup the Eduroam connection see wifi-and-eduroam

Of course, Eduroam accounts from other universities will be able to connect as well. For people from leiden, be sure to use your university (ULCN) account, in the format lastnameinitials@vuw.leidenuniv.nl ; for Leiden students: use your student number account (so: NOT your institute account).

Leiden's implementation of Eduroam is managed by the central IT department ISSC, so for questions, contact helpdesk@issc.leidenuniv.nl

As of February 2018, you can temporarily arrange access to the eduroam Wi-Fi network for your guests or visitors via Eduroam Visitor Access (EVA) website.

• Visit https://eva.eduroam.nl
• Select `Leiden University'
• Login with your ULCN-account
• Click on `create visitor'

Your visitor(s) will be notified via e-mail and/or SMS that a temporary account has been created. You can give access to up to 3 guests at a time per month. The access is valid for 5 days. You can decide for yourself which 5 days your visitor should have access. After 5 days, the temporary account will automatically expire.

And it will give you additional capabilities not provided by other networks such as printing on local printers of your institute. You do not need a key to connect to this network and this means that all your traffic is traveling the ether unencrypted.
