Also university wifi eduroam doesn’t work on Fedora for me because legacy TLS connection is not supported in Fedora (at least I couldn’t get it to work).
When the WiFi relies on insecure encryption, the problem will only be delayed on Mint because Mint’s underlying Ubuntu core is just older. Once a newer security policy comes to Mint, it will have exactly the same problem. The actual solution is for you university to update the WiFi encryption. In the meantime, according to fedoraproject.org/wiki/…/StrongCryptoSettings2#Up… the security defaults of Fedora can be rolled back to an earlier level quite easily.
