Wi-Fi Frequently Asked Questions (FAQs)

What is eduroam?

eduroam is a JANET Roaming Service (JRS) that provides an infrastructure for a user to use their UCL credentials (e.g. ucxxzano@ucl.ac.uk) to access the Internet from UCL or any participating Institution. The instructions for connecting are the same regardless of location. However, it is recommended you (a) check eduroam works here at UCL and (b) check the JRS eduroam web site for details on the status of eduroam at participating institutions.

How do I connect to eduroam?

eduroam is supported on any Wi-Fi enabled device. View our connection guides for instructions on how to set eduroam up on your device.

How do I connect to eduroam at other institutions?

You use the same connection instructions and UCL userid and password at other Institutions as you do here at UCL. We (UCL) are currently at JRS Tier-2 - this allows the Institution to support either WPA/TKIP or WPA2/AES encryption (or both) - UCL supports both. Support at other Institutions may differ. It is therefore recommended you (a) check eduroam works here at UCL and (b) check the JRS eduroam web site for details on the status of eduroam at participating Institutions.

All users of the network must be aware of and abide by the UCL Computing Regulations and the JANET Acceptable Use Policy » when connecting to any UCL Network. Traffic, per se, is not actively monitored. However, logging is in place to uniquely identify individual users if a breach of regulations is reported or malicious activity detected.
