Frequently Asked Questions?


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.

What is RoamNet?

RoamNet is a Wireless and Wired service provided at UCL since 2004. As of September 2011, RoamNet Wireless was discontinued. RoamNet Wired will continue to operate until an alternative is available.

How do I connect to eduroam?

Authenticating to the eduroam SSID (Wireless Broadcast) requires a valid UCL userid and password. Your UCL userid is provided on the front of your registration slip and must be appended with @ucl.ac.uk (e.g. ucxxzano@ucl.ac.uk). It is NOT the user name @live.ucl.ac.uk! Your Operating System may require additional configuration to connect. Please refer to the Connection Guides for further information.

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.

No, we are currently working on an eduroam Wired service which uses 802.1X authentication. This will be advertised when available. In the meantime, the RoamNet Wired service is available in a number of locations throughout UCL.

What is my IP Address?

Upon successful authentication, your IP address is automatically allocated using DHCP.

For Internal users (@ucl.ac.uk), a Private IP address from 10.111.0.0/16 is allocated. When accessing resources (e.g. Internet, Email) your address will be translated to one of the following:

  • 144.82.8.0/22 (144.82.8.1 - 144.82.11.254)
  • 144.82.160.0/19 (144.82.160.1 - 144.82.191.254)
  • 144.82.240.0/21 (144.82.240.1 - 144.82.247.254)

Traffic on this subnet is presented Inside the Institutional Firewall (IFW).

For External users (not @ucl.ac.uk), an IP address from the  144.82.96.0/22 (144.82.96.1 - 144.82.99.254) subnet is allocated. Traffic on this subnet is presented Outside the Institutional Firewall (IFW).

To determine your actual IP address you can either check your adapter configuration or type "My IP Address" in your web browser search engine.

Is eduroam Traffic Monitored?

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 sa, 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.

How do I clear Cached User Credentials (Shared PC)?

On a majority of platforms (e.g. Microsoft, Apple Mac) credentials are automatically cached for reuse. This is not ideal on shared PC's. The instructions below outline how to clear cached credentials.

  • Microsoft Windows the following Microsoft article describes how to manually clear credentials. You can also create a VBS script to automate the process as highlighted in the article http://support.microsoft.com/kb/823731 »
  • Apple Mac OS X, modify the eduroam 802.1x User Profile (Airport > Advanced... button > 802.1x tab) and tick Always prompt for password.
