I've been trying to get my Beaglebone Black to connect to internet using an ethernet cable plugged direct into my Netgear router. I have tried many things but nothing has worked so far.

Here are some relevant outputs.

systemctl

# Yesterday, internet not working
● networking.service loaded failed failed Raise network interfaces
# Today after reflashing beaglebone, internet still not working
networking.service loaded active exited Raise network interfaces

I have no idea how to fix this. It started working yesterday when I started writing this question then it started working mysteriously. I rebooted this morning and it's not working again.

Go to /etc/network/interfaces then add:

auto eth0
iface eth0 inet static
 address 192.168.0.100 # or whatever static IP you want
 netmask 255.255.255.0
 gateway 192.168.0.1

After rebooting, the Beaglebone pings Google successfully.
