I take it, the dkms debian driver didn't work?
No suitable device was found. The issue is with the driver not working/wrong/ or not installed correctly/ or with the device permissions i/e Network Manager permissions to the device. Network Manager seems to be working properly though.You can check your /etc/network/interfaces file for eth configuration though I expect all is already there properly.https://wiki.debian.org/NetworkConfiguration#Setting_up_an_Ethernet_Interface

Here's what I got:Code: [Select]DEVICE TYPE STATE CONNECTION wlp2s0 wifi connected FiOS-QW2C2 enp0s25 ethernet unavailable -- lo loopback unmanaged -- Thank you. I feel confident we'll get it this weekend.

sudo ifdown enp0s25then sudo ifup enp0s25
run: nmcli dev statusThis will show if the correct logical name 'enp0s25' of your device is listed as up.
If all this is correct and there is still no connection make sure your firewall is configured correctly. Perhaps you changed it at some point and forgot about it.
If all is well there and you are still not connected you can try changing the ifupdown plugin configuration in your /etc/NetworkManager/NetworkManager.conf file from false to true.
Some report a fix by having the latest BIOS installed.
Also, output please of:Code: [Select]sudo lshw -C net

Network Manager can be quirky with things that involve changing some drivers not in a repository kernel version.
run the following: Code: [Select]nmcli connection show
nmcli connection show

And then run: nmcli connection up 'Wired connection 1' (or whichever you wish to activate)
Error: Connection activation failed: No suitable device found for this connection.
Try changing the wire itself and/or the port in the switch/router it's connected too.
Even easier, install the dkms deb package - https://github.com/koljah-de/e1000e-dkms-debian/releases
