Forgot to add: This is on a Thinkpad X250, Fedora 26 running kernel 4.12.11-300.fc26.x86_64

Comment 3 dimitris 2017-09-14 16:40:14 UTC

Update: If I `systemctl restart ModemManager.service` I can (sometimes) connect again.  I'm adding this comment over the LTE connection.  Next time I reproduce I'll update the logs.
