Hello,
On my RPI 1'st gen, samba not working after device reboot.
Then I login from Windows 10 TH2 or Ubuntu 18.04 I have error message with windows network diagnostics, or on Ubuntu not connecting without any error.
PS: I have polish system.
PSS: LibreELEC config tile not working fine, refreshing screen after few minutes and I must wait few minutes for load config wizard.
