Installed Debian yesterday and have had a pleasant experience except for my inability to get the Wired Connection working. I have a Wireless connection that connects and allows me to access Internet. The Wired connection activates, but does not have any Internet. I installed network-manager in hopes that it would do something.
ip a (when I am connected to both wireless and wired)

Noticed that the eno1 is missing an IPv4 address.
Also tried tweaking files in
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). source /etc/network/interfaces.d/* # The loopback network interface auto lo iface lo inet loopback
cat /etc/network/interfaces.d/* auto lo iface lo inet loopback
auto eth0 iface eth0 inet dhcp
One thing that I noticed so far is that my Ethernet is called eth0 in interfaces.d, while it's called eno1 from ip a. I tried to update the etho0 to eno1 and then restart the service, but was not successful. From my understanding of network-manager, the interfaces file should be ignored now?
[main] plugins=ifupdown,keyfile [ifupdown] managed=true
Any help would be appreciated!
