Thanks . It worked for me.
- I had the IP address but no internet connection
- The LAN port was active
- I had assigned static IP address
My /etc/network/interfaces
had the following content:
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
iface enp4s8 inet static
address 192.168.2.251
netmask 255.255.255.0
network 192.168.2.0
I was having ifconfig
output as (this is manual edit - it was somewhat like this)
~$ ifconfig
enp4s8 Link encap:Ethernet HWaddr 00:19:d1:73:b7:11

I changed the /etc/network/interfaces
to:
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto enp4s8
#iface enp4s8 inet dhcp
#iface enp4s8 inet static
#address 192.168.2.251
#netmask 255.255.255.0
#network 192.168.2.0
#broadcast 192.168.2.255
#gateway 192.168.2.1
#dns-nameservers 192.168.2.1
Then I followed the steps included in the answer above:
sudo service network-manager stop
sudo ifconfig enp4s8 up
sudo dhclient enp4s8
sudo service network-manager start
This is when I got the connection to the network, these steps worked.
FYI - The Live CD also had internet connection. I did not copy the files from Live CD.
/etc/network/interfaces
file?
