These instructions are for configuring eduroam for Windows 8 and 10. Before you begin, make sure you're in a location where the eduroam wireless network is available and have your email address ready.

1. Go to and download the eduroam Configuration Access Tool (CAT) tool. If you are asked whether to download or run the program choose download.
2. Double click the file from the folder you have downloaded it to. This is usually your Downloads Folder
3. Where the tool asks for your username, you need to enter your RNCM email address in the format

Where it asks for your password, you need to enter your RNCM login password

A Security Warning will be displayed, asking you to confirm the installation of a certificate from RNCM eduroam service. It is strongly recommended that you check the value shown against the "Thumbprint (sha256)" is 7971BBD4 A58874AB3 5C90B049 8DCC832 8F667A99.

The eduroam CAT will then set up your eduroam connection automatically.


Internet Explorer or Edge reports that the eduroam CAT file is corrupt when I try to run the file within the web browser.

Please download and save the file, and then run it from your usual download folder instead.

A warning that Windows SmartScreen cannot be reached is displayed.

This will occur on Windows 10, if you are disconnected from the network, when you try and install the CAT.  It is recommended that you connect to the network via RNCM-General, before doing this.  If you cannot connect in another way, you should select "Run anyway".

My anti-virus software (such as McAfee) detects the file as malware.

This is a false positive. Please turn off McAfee temporarily if you encounter this problem, but don't forget to turn it back on afterwards!

I followed the instructions but eduroam still isn't working.

Try removing the non-working profile and starting again afresh. The uninstallation process varies according to the version of Windows you're running, here's an example for Windows 7:

  1. Left-click on the 'Wireless application' icon in the system tray. It looks like a series of increasing semi-circles.
  2. Click 'Open Network and Sharing Center'.
  3. Click 'Manage Wireless Networks', on the left of the window.
  4. In the 'Wireless Network Management' window, select 'eduroam' and click 'Remove' to delete the eduroam profile.

Now run through the instructions again, making sure you enter the correct user name and password.
