eduroam will provide you with wireless Internet access. When you are in Cambridge you can choose to connect wirelessly via either eduroam, the University of Cambridge Wireless Service (previously known as Lapwing) or, if one exists, a wireless service provided by your College or Institution. A list of institutions with Computing Service provided wireless access points is available.
If you are connecting to eduroam in Cambridge, the University Information Services offer eduroam supporting WPA2-AES, with no IPv6 support. Details of port restrictions are given on a separate page
When you are away from Cambridge, and at a site that also participates in eduroam, you will be able to connect to their eduroam service using your Cambridge eduroam credentials. This means you will be able to access most of the services you use when you are connected to the CUDN. For some local services you will need to use your Raven password as your computer will not be using a Cambridge address. If you also have a VPDN account you can use that to let your computer appear as if it were on the CUDN.
Most sites participating in eduroam use the eduroam network name. If you go to a site that does not, you should follow local instructions to connect to the correct service.
Note that when you use eduroam at another organisation you are bound by our AUP (), the Janet AUP and the AUP of the organisation you are visiting. Breach of AUP could result in disciplinary procedures.
Before you leave Cambridge
- Check whether the institution you are visiting participates in eduroam (UK institutions or elsewhere.)
- Make sure you have configured, and checked, your system. Configuration notes are currently available for a number of platforms (see below).
Configuration notes for various platforms and devices
A set of generic instructions is available. This may help users with devices not listed below.
For Windows platforms (8, 7, Vista) we use the eduroam CAT (Configuration Assistant Tool).
Before you follow the link to download the tool for your Windows version:
- You must be connected to the network fully (e.g. using the University Wireless Service (previously known as Lapwing), or an office, College or home connection).
- Make sure that you have your credentials (eduroam identifier and Network access token (username and password)) from the UCS Tokens service.
Now you need to download and then run the correct tool for your Windows version. Where the tool asks for your username you need to enter your eduroam identifier, where it asks for your password you need to enter your Network access token.
The eduroam CAT sets the configuration automatically to leave it in the state it would be in if you had gone through the steps manually. It does not leave anything else (e.g. utility, autoupdating application) on your system.
Note that the tool is automatically downloaded. Check your usual download location. You are then returned to this page.
Occasionally, McAfee may detect this file as malware. This is a false positive. Please turn off McAfee temporarily if you have this problem.
If you are having problems, for example eduroam access is still not working after following the instructions for your version of Windows, see What do I do if I'm having problems connecting to eduroam from my Windows system?
- MacOS Lion (10.7), Mountain Lion (10.8), Mavericks (10.9) and Yosemite (10.10)
- MacOS 10.6 (Snow Leopard)
- MacOS 10.5 (Leopard)
- MacOS 10.4 (Tiger)
Janet(UK)'s TERENA contract for server certificates means that the Comodo AddTrust External CA Root certificate needs to be added to the 802.1X profile. This may require you to remove the current profile and then create the profile again; see Removal of 802.1X profiles on OS X
If you are having problems, for example eduroam access is still not working after following the instructions for your version of Mac OS, see What do I do if I'm having problems connecting to eduroam from my Mac?
Linux - Ubuntu
- Ubuntu 10.04 LTS "Lucid Lynx" (openSuSE is similar)
- Android - Note prepared using a HTC Hero running Android 2.1 (Eclair). There are likely to be some differences with other Android devices.
We have had confirmation that this also works on a chromebook and on the Kindle Fire.
There are connection issues with some (but not all) Android 2.3x systems - see Problems with Android 2.3.x devices connecting to eduroam.
- iPhone and iPod Touch
- Microsoft Surface
- Windows Mobile 6.x and above
Janet(UK)'s TERENA contract for server certificates means that the Comodo AddTrust External CA Root certificate is needed. Some phones (including Nokia and Sony Ericsson) do not have this certificate in their list of Certification Authorities. We have provided instructions for converting the root CA for use on mobile devices.
