Check network settings

For SSHnet your computer should be configured with ‘obtain IP address = automatic’ and ‘obtain DNS address = automatic’ (these settings are known as ‘DHCP’). An IP address ‘0.0.0.0’ or beginning with ‘169.254.’ indicates that your computer has no connection.
This may be caused by incorrect network settings.
 

Make sure that your computer is configured for use in a LAN, not for ‘dial up’ or ‘broadband’.
