Spontanious Networking Problem [CLOSED]

Mar 14, 2021

Once again I have been bested by GNU/Linux.

Well, all of a sudden Ethernet broke. I hadn't configured wireless yet (my current networking card uses proprietary drivers; different problem for a different time), so on my Debian installation I don't have internet. I know this isn't a hardware problem because if I boot into windows, everything works fine. I am also unsure it's a driver issue because before, it just worked. I didn't even update anything. It's broken.

As everything is a science and there had to be a casuing factor, I did some diagnostics. When I use the cat command on /etc/network/interfaces.d/, I get this:

    auto eth0
    allow-hotplug eth0
    iface eth0 inet dhcp

Upon further research, this does seem to be a problem. No idea what to do though.

Pinging anything or using any built in networking tools just says it cannot find network.

One more thing that may be of use to anyone who is willing to help: Someone did have a similar issue here on this old StackExchange thread but did not go into detail of how they fixed it: https://unix.stackexchange.com/questions/323488/no-internet-connection-debian
