Re: [ solved ]problem when dissconnected

Did you set host name of your computer.
https://wiki.archlinux.org/index.php/Be … e#Hostname

What's the result of this command

hostname

localhost is default hostname. Properly set your hostname as described in wiki
https://wiki.archlinux.org/index.php/Be … e#Hostname

I had faced similar issue in the past, and the culprit was hostanme.
So first explictly set hostname, reboot then see if still problem persist.
