To fix internet access for Kodi on Batocera.linux there is a very simple thing to do !
Go to your
Settings/Services -> SMB client
And change its two parameters
Minimum protocol version : Maximum protocol version :
Minimum protocol version : SMBv2 Maximum protocol version : SMBv3
Minimum protocol version
Set the minimum SMB protocol version to negotiate when making connections. Forcing SMBv2 may be required to prevent SMBv1 use on some OS. Please be aware, that we do not recommend to use SMBv1 at all for security reasons as it's known vulnarable. So please enable SMBv1 only if you know what you are doing.
Maximum protocol version
Set the maximum SMB protocol version to negotiate when making connections. Forcing SMBv2 or SMBv1 compatibility may be required with older NAS and Windows shares. Please make sure if the SMB server you want to connect to supports at least SMBv2 and do required changes on the server side (and also for the shares) before enabling SMBv1.
Specific cases Some NAS vendors support only older versions of SMB. Known examples are:
