Comment 10 for bug 1418777

I confirm, issue still exists in Mint 18. I'm on a fresh install of Mint 18 64bit.
OS: Mint 18 Cinnamon 64bit
Cinnamon: 3.0.7
kernel: 4.4.0-53

Via Hidden Networks method not work for me; is present only LEAP auth, and I need PEAP authentication. I've also try using LEAP but does not work.

I've also try to edit manually /etc/NetworkManager/system-connections/*SSIDNAME* file without results. I try to connect, connection fails and is asked to me to insert password (as when during a login, is inserted a wrong password). I retry to connect but fails.
And now if I check configuration file under /etc/NetworkManager/system-connections/ is overwritten with system configuration.
