I think I solved the issue. In my /etc/freeradius/radiusd.conf, I changed the daily counter.
Previously, there was : counter daily { filename = ${raddbdir}/db.daily key = User-Name count-attribute = Acct-Session-Time # reset = daily reset = 1h counter-name = Daily-Session-Time check-name = Max-Daily-Session reply-name = Session-Timeout allowed-servicetype = Framed-User cache-size = 5000 } I changed it to : counter daily { filename = ${raddbdir}/db.daily key = User-Name count-attribute = Acct-Session-Time reset = never # reset = 1h counter-name = Daily-Session-Time check-name = Max-Daily-Session reply-name = Session-Timeout allowed-servicetype = Framed-User cache-size = 5000 } And it seems to work, I passed more than an hour now without being disconnected. I don't know how this can be related to any change in NetworkManager, it's been a while since I even opened the FreeRADIUS config file. Yet, this seems to improve situation. -- Frequent Network Manager disconnections from WPA EAP-TLS network https://bugs.launchpad.net/bugs/377227 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
