If a self-signed certificate (or any certificate from an untrusted CA) is in use, most clients will reject the connection since they cannot validate the server's identity.
For troubleshooting purposes, server certificate validation can be disabled on one or multiple clients, allowing those clients to connect regardless of the certificate in use.
WPA2-Enterprise has been around since 2004 and is still considered the gold standard for wireless network security, delivering over-the-air encryption and a high level of security.
By default, 802.1X authentication on Window 8.1/10 consists of not only client authentication, but also server authentication, which requires the server (here is the Vigor AP) to provide certificate information to the client.

In order to connect to eduroam network in future, simply bring up Wireless Network Connection window by double-clicking its icon in the tray bar , select eduroam network and click on Connect.
WPA2 is more secure than WPA because WPA2 uses Advanced Encryption Standard (AES) encryption and meets the Federal Information Processing Security (FIPS) 140-2 requirements.
To use WPA2 on a wireless network, the wireless router, the wireless network adapter and the operating system must support WPA2.
By default, Windows connects to any type of wireless network.
