Both the NOOBS and Raspbian issues suggest that you don't have a working network connection.
Do you have any reason to believe that the cable you are using and the router port you are connecting to are both in working order? (Can you check them with another system, like a laptop?)
Does the network (probably the router) have a dhcp server that will supply a valid IP address and other configuration details to a new workstation? (Have you ever connected another 'new' system and had it work without further configuration?)
[The underlying point is that an RPi running Raspbian will 'just work' if it is booted up while connected to a working network that will support dhcp.]
