Update to university Wi-Fi – action required

August 26th, 2022

On Tuesday 6 September at 12am, Digital and Technology Services (DTS) will be updating the eduroam wireless security certificates to maintain a secure wireless network for all users.

Following the update, all eduroam users will see a warning on their device stating that their connection “may not be secure”.

You may be prompted to log in to eduroam again to accept the new certificate and ensure a secure internet connection via eduroam.

In order to reconnect to university Wi-Fi after the update, you will need to:

  1. Accept the new certificate when prompted OR
  2. Re-connect using the eduroam Configuration Assistance Tool (CAT) or Geteduroam
  3. Failing that, forget the eduroam wireless network and re-connect to it – instructions on how to do this can be found on the IT Services website

Reminder – for eduroam, your username is your university email address. For example:

  • Undergraduate and Postgraduate Taught students: ‘username@nottingham.ac.uk’
  • Postgraduate Researchers, Staff and Associates*: ‘firstname.lastname@nottingham.ac.uk’

*Associates without a university email address should use: ‘username@nottingham.ac.uk’

University-managed Windows devices should automatically update if they are connected to the Virtual Private Network whilst being off-campus.

If the update needs to be started manually, go to Start > UoN Network > Eduroam Setup 2022.09 which will load a screen to take you through each step (or search for “Eduroam Setup 2022.09” after you click on the Windows icon).

Although you may be able to connect to the eduroam wireless network without validating the server certificate, your connection will not be secure, and your data may be at risk.

Certificate security information

After the update, you may experience a security or certificate warning when first connecting to eduroam. To ensure your safety, check that the certificate you are presented with matches the following information:

You can also install the certificate yourself before connecting by using the CAT tool.
