We’ve confirmed an issue affecting Linux wireless clients using wpa_supplicant version 2.10, which includes the already-released Ubuntu 22.04. These clients are unable to connect to both eduroam and EECS-Secure due to an incompatibility in TLS negotiation methods.
We are working with our vendor to see if the eduroam and EECS-Secure authentication servers can be updated to comply with the relevant RFC. Some Linux distributions, including Ubuntu 22.04 and Fedora 36, are working on patches to address this issue from the client side.
Until a fix is deployed for your distro or our software, we suggest those affected by this issue employ the fix described in this link:
Our thanks to Alex Reinking, a member of the EECS community, who first reported this issue and also provided the fix linked above.
