Ethernet Not Working, Intel e1000e 82578DC rev 06

[jerryc]

Just did an LL install on a Win7 box and now we have no ethernet access. Fortunately, we have wifi working on it.

Here's what I got:

Code:

lspci | grep -i ethernet
00:19.0 Ethernet controller: Intel Corporation 82578DC Gigabit Network Connection (rev 06)

I tried googling it, but I couldn't find any simple instructions that work. Intel has a driver here:

https://downloadcenter.intel.com/downloa...duct=55351

but, even with some nix experience, I couldn't follow the instructions. They talk about building an .rpm, but I've been a .deb guy for way too many years.

I tried the instructions here:

https://www.intel.com/content/www/us/en/...ducts.html

Here's what I got:

Code:

Does anybody know a simple step by step guide to make this work on LL?

Thank you.

I've done some more digging. The driver needed is e1000e. It's supposed to be merged into the kernel already now.

I ran:

Code:

lsmod | grep e1000

and got:

Code:

e1000e                249856  0
ptp                    20480  1 e1000e

So, it appears as though I already have the proper driver. However, it's still not working.

Any ideas?

Thank you for your help on this.

More info. I ran:

Code:

lspci -nnk | grep 0200 -A3

and got:

Code:

00:19.0 Ethernet controller [0200]: Intel Corporation 82578DC Gigabit Network Connection [8086:10f0] (rev 06)
    Subsystem: Acer Incorporated [ALI] 82578DC Gigabit Network Connection [1025:8000]
    Kernel driver in use: e1000e
    Kernel modules: e1000e

My guess it's probably a simple configuration issue.

Thank you again.

Here's more:

Code:

route -n

yields:

Code:

No IP address shows for the ethernet router.

Per TC, I ran:

Code:

nmcli connection show

and got:

Code:

I also ran:

Code:

sudo ip addr show

and got:

Code:

I sure hope some of this is helping. Thank you.

Well network manager is not picking up the interface system name. Looks like the kernel is updated for the card but not network manager. Try manually creating a new wired connection in network manager to enp0s25.

I was intending to write on this subject myself, but I found this at tecmint.

Even more. The relevant output of:

Code:

inxi -Fxz:

is:

Code:

Network:   Card-1: Intel 82578DC Gigabit Network Connection
           driver: e1000e v: 3.6.0-NAPI port: e880 bus-ID: 00:19.0
           IF: enp0s25 state: down mac: <filter>

Maybe "state: down" is something I can change, like maybe to "state:up."

Try manually creating a new wired connection in network manager to enp0s25.

Tried it. It appears enp0s25 is already showing in the network manager for the wired connection as the same device:

Code:

enp0s25 (60:EB:69:DE:64:EC)

Now, I have two connections in network manager not working, wired connection 1 and ethernet collection 1.

Thanks for helping dig into this. I suspect it's something simple, just not easy to find, yet.

[jerryc]

Neither of these worked, either:

Code:

sudo ip link set dev enp0s25 up

Code:

sudo /sbin/ifconfig enp0s25 up
