I have installed Ubuntu 16.04 LTS on my Desktop, but Ethernet is not connected. My Computer uses Intel Ethernet Connection I219-LM. In my opnion, Ubuntu doesn't have installed a proposal network driver. I can't find ethernet driver.

  • The driver for your device is e1000e. Does it load without error? sudo modprobe e1000e Is there any clue in the log? dmesg | grep e1000e Welcome to Ask Ubuntu. – chili555 Aug 21 '18 at 20:08
  • I’m having the same issue. The i219 isn’t being detected. When I run those commands the e1000e driver loads and there are no errors. – Kevin Vasko Oct 31 '18 at 20:59

Same ethernet adaptor for me on my ubuntu 16.

This worked:

  • Download e1000e-3.4.2.1 (Check latest on Intel website).

  • Got the tar.gz file downloaded untar it:

    tar xfv e1000e-3.4.2.1.tar.gz
    
  • Goto src directory

    cd src
    
  • Compile and install

    sudo make install   
    
  • Reboot

This worked for me.

  • And for me too in Debian9 . Thanks! – Rfraile Jul 29 '19 at 9:59
  • This appears to have worked for me, too. Ubuntu 20.04, Thinkpad T460s w/ i219-LM. After compiling the new driver and rebooting it's been hours since I've seen my wired internet drop. Fingers crossed for more hours to come. Note: The version I downloaded was e1000e 3.8.4, which apparently was written in 2019. I'm guessing this will be the final version. – AveryFreeman Aug 13 '20 at 17:16

I met the same case that I can't see the network card on my Linux only computer which uses Intel Ethernet card. And installing the Intel driver didn't help. There's another topic about an "Wired Unmanaged" Ethernet card, that Lou Burnard suggested to:

  1. Edit the /etc/NetworkManager/NetworkManager.confand change the line managed=false to managed=true
  2. Restart network manager with sudo service network-manager restart.
    And for me I need to wait for it to work.

  • First time I've touched that file and it says managed=false already, but I did install a bridge with bridge-utils for KVM, so that might have changed it without my knowing. – AveryFreeman Aug 13 '20 at 17:20
