Introduction

Connecting to the Eduroam wireless network on a fresh Ubuntu 24.04 installation can be a challenging task, especially when the university's network uses deprecated TLS protocols. In this article, we will explore the possible causes of this issue and provide a step-by-step guide to resolve the problem.

Understanding Eduroam and TLS Protocols

Eduroam is a secure wireless network service that allows students, researchers, and staff to access the internet and other network resources at participating institutions. The service uses a combination of WPA2 encryption and RADIUS authentication to provide a secure connection.

TLS (Transport Layer Security) protocols are used to encrypt data transmitted between the client and server. However, some universities may still use deprecated TLS protocols, which can cause issues with modern operating systems like Ubuntu 24.04.

Connection timeout: The connection may timeout, and you may not be able to access the network.
No internet access: You may not be able to access the internet or other network resources.

The causes of these issues can be attributed to the following factors:

Deprecated TLS protocols: As mentioned earlier, some universities may still use deprecated TLS protocols, which can cause issues with modern operating systems.
