eth0 - No Such Device

Postby friesian49 » Sat Oct 21, 2017 6:47 pm

All,
I have a friend's Dell computer that had malware on the Windows 7, had a heck of a time removing it and decided to wipe the drive and load Linux Mint 18 Sarah. I've used this install on my laptop with no issues. The install worked great, but I'm unable to connect to my router via ethernet. I've ran a couple of commands from the user forum and searching on Google. I'm not sure if it's a simple method of downloading the Realtek drivers or if there's more going on. We were online with the Windows 7 a day ago with no issues. This is a clean install, not a dual boot.

Ifconfig - a
Shows enp2s- and lo. eth0 is not listed.

sudo ethtool eth0
cannot get device settings: no such device
cannot get wake-on LAN; no such device.

lspci
Ethernet controller: Realtek Semiconductor Co

/etc/network/interfaces.d
this file is empty

Any thoughts? I've been working on Linux a bit, by no means am I an expert. Learn something everyday, but wasn't expecting to have issues with the dang ethernet!

The lan would be enp2s not eth0.

systemd is different with the network connections and show it as so.

All,

It was a driver issue. Updated the Realtek drivers and got connected. Thanks for the help!
