Most devices will connect to eduroam without problems, but occasionally devices don't have the correct wireless certificates, or need to have system settings changed.
This can be fixed by installing and running an 'eduroam CAT file'. The CAT file will make all the changes your device needs to connect to the eduroam service.
See instructions for your device (on the left) to find out how to download and use them.
CAT stands for Configuration Assistance Tool.
