Estou tentando fazer com que o meu Beaglebone Black se conecte à Internet usando um cabo ethernet conectado diretamente ao meu roteador Netgear. Eu tentei muitas coisas, mas nada funcionou até agora.
Aqui estão alguns resultados relevantes.
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

Eu não tenho ideia de como consertar isso. Começou a trabalhar ontem quando comecei a escrever esta pergunta e começou a trabalhar misteriosamente. Eu reiniciei esta manhã e não está funcionando novamente.
Vá para /etc/network/interfaces e adicione:
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
Após a reinicialização, o Beaglebone pinga o Google com sucesso.
