Can you help me configure my device?
Unfortunately, we don’t have the resources to provide individual assistance and feedback on device compatibility with eduroam or your local wireless setup.
The eduroam in University of Ruse is self serviceable – this means that configuration of your device (laptop, tablet, mobile phone, etc.) is your responsibility.
