Connecting to eduroam

The wireless network at UK universities is called eduroam. To connect to eduroam you will need to provide your username and password. However, when typing in your username add the text - this will allow you to connect at Sheffield but if you visit another University your device will automatically connect to eduroam there too!

Using the CAT installer

  1. Open the Google Play store app
  2. Search for the "eduroamCAT" app
  3. Once the app has been located, select install and accept the download
  4. After the installation of the eduroam CAT app has completed, open it
  5. If you are on campus, the app should detect your locations and show University of Sheffield under Nearby Configs, select this option
  6. If, however, you are not on campus or away from the city, you may need to select the manual search option and enter Sheffield
  7. Select University of Sheffield, followed by install on the configuration summary file page
  8. Enter your username and password followed by and select install
  9. eduroam should then be installed on your device and you should see it connect successfully
  10. After installation, you can remove the eduroam CAT app from your device if you wish and your device will remain connected to eduroam

Please note: If you have manually configured your eduroam connection, rather than using the app, the December 2020 security update on android 11 prohibits the ability to use the 'Do Not Validate' option for security certificates. Please use the app to install certificates or follow the links below:

  • It has come to our attention that some android 11 devices may not work with the eduroam CAT app. An alternative app is now available from Play Store called geteduroam. Android 11 users should download this and follow the prompts similar to the steps above.
  • If you have previously created your eduroam profile without using one of the android apps you may need to completely remove/forget the network before running the application. If you have unsuccessfully used the CAT app on android 11 you should forget the network before attempting to use the geteduroam app.
  • Android 11 devices using the CAT tool may need to disable anonymous outer identity by unticking the option box in order for it to be successful.

Most problems with connecting phones to the wireless network are related to passwords:

  • If you have followed the instructions above and your phone does not connect, you may need to change your password to update the system. Use the link below to log into the account management page and click the option to change your password.
  • Some people are still trying to use a second password (RATS password for VPN) to connect to wireless. This will not work, use your normal University password.

Change your Passwords

If you still have trouble connecting, talk to any member of staff in the Information Commons or visit the Computing Centre. We will be happy to help.
