Hello, I use a config with EAP-Method=PEAP and EAP-PEAP-Phase2-Method=MSCHAPV2, which results in (random?) core-dump. [0] This happens after authentication timeout or tls_reset_handshake. [1] My system is an uptodate arch linux machine with iwd 1.2-1, Linux 5.4.2-arch1-1, glibc 2.30-3. If you need more information I am happy to provide it. There is no problem with PreSharedKey Wifis. Thank you for your time and this great tool. [0] http://sprunge.us/5Ez0pP [1] http://sprunge.us/c13AYe
