Where can I access eduroam on campus?
eduroam is available on all three campuses. Access is prioritised for teaching and learning spaces, including lecture theatres and IT labs. eduroam is also available in some staff offices and student social spaces.
eduroam is not available in halls of residence (but the student halls network is), although some rooms may receive a weak signal if close to other university buildings where eduroam is present.
To report a weak eduroam signal on campus, please contact the IT Service Desk with details of the building and room number so a survey can be arranged. Please be aware that the installation of access points in some of our buildings is subject to approval by English Heritage, so may not always be possible.

What is eduroam?
eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community. It is the recommended way for staff and students to access Wi-Fi on campus.
Is eduroam safe?
eduroam is based on the most secure encryption and authentication standards available today. It is far more secure than the average hotspot found in shopping centres, coffee shops and home Wi-Fi setups.
eduroam uses TLS (Transport Layer Security) encryption for authentication, which provides secure communication over the Internet. In line with best practices security recommendation we only use TLS v1.2. Your device must support this to connect. Please ensure that all of your devices have the most up to date OS and patches.
Can I setup more than one device on the eduroam wireless network?
Yes, either set up manually or use the geteduroam app to configure your laptop, phone, tablet etc.
Can I connect without using the app?
Yes - you can install an eduroam setup file, known as a CAT file, on your device. The CAT file will make all the changes your device needs to connect to eduroam at the university.
You can . The website will automatically detect your operating system and give you a link to download the configuration tool.
Use the 'Choose another installer to download' link to find configurations for alternative operating systems.
To connect without the CAT file:
Some newer operating systems have a feature that scrambles the device MAC when on Wi-Fi. This feature must be turned off to connect the device to eduroam. If it is enabled, access to eduroam will drop out if you move between Wi-Fi access points on campus.

Why should I use eduroam instead of my mobile data?
We have Wi-Fi access points across all of our buildings in areas where your mobile data signal may not reach, such as basements and historic buildings with thick walls.
Setting eduroam up before you arrive on campus means that you don't have to rely on a mobile data signal to get connected to our network.
