network UNCLAIMED (Intel I219-V) --ubuntu 16.04.2LTS

[SOLVED]

I'm at a loss right now. Built new PC. Installed Win10 and everything is working fine (posting this from Win10). Got ubuntu up and running with internet working just fine. Not sure what happened but at some point lost my ethernet connection.

Booted into ubuntu no internet. Booted into ubuntu liveCD no internet. Booted into Manjaro liveCD no internet. Bunsenlabs, etc.

The only thing I did between installing ubuntu and it working just fine and ethernet connection getting borked was update my BIOS for the Asus Prime 270a. Poured through BIOS settings to try and find any LAN conflicts and reset defaults to try and fix. No go. Not sure how or why a BIOS update could screw up linux ethernet that badly though. I have not tried rolling back BIOS yet as I cannot find the original version of the BIOS I had running yet. Might try an older version soon.

Trying building Intel drivers for ethernet was a no go as well.

Not sure what to do next. What gives me pause is that I had internet up and running on ubuntu which makes me think it's fixable. But the fact that all livecd's internet connection are not working either makes me think it's hardware/BIOS problem. But again ethernet works fine in win10. I can post ethernet.txt or whatever else might be needed for assistance.

Only bonus out of this is that I really got to brush up on my terminal skills. Any help would be much appreciated.

I have exactly same problem. Except my MB is Asus ROG STRIX Z270G GAMING

Turns out this problem is quite old. Here's how I solved it.

There is an error message in dmesg:

[ 1.216090] e1000e 0000:00:1f.6: The NVM Checksum Is Not Valid

Download driver here:
https://downloadcenter.intel.com/dow...?product=71307

(I used version 3.3.5.3)


Extract & cd into e1000e-3.3.5.3/src


Edit nvm.c, function e1000e_validate_nvm_checksum_generic (line 563) to:

s32 e1000e_validate_nvm_checksum_generic(struct e1000_hw *hw)
{
    /*
    s32 ret_val;
    u16 checksum = 0;
    u16 i, nvm_data;


    for (i = 0; i < (NVM_CHECKSUM_REG + 1); i++) {
        ret_val = e1000_read_nvm(hw, i, 1, &nvm_data);
        if (ret_val) {
            e_dbg("NVM Read Error\n");
            return ret_val;
        }
        checksum += nvm_data;
    }


    if (checksum != (u16)NVM_SUM) {
        e_dbg("NVM Checksum Invalid\n");
        return -E1000_ERR_NVM;
    }
    */


    return 0;
}

Build & install

make


sudo rmmod e1000e
sudo make install
sudo modprobe e1000e

It should work now

Much love & many thanks ZhurX!!!! That worked like a charm!!!
[EDIT]
I gotta rmmod; modprobe every time I restart but whatever... it works!

Yeah, that's weird. AFAIK the change should be persistent since the make install runs depmod. Anyhow, I fixed it by running

sudo dpkg-reconfigure linux-image-$(uname -r)

Thank you so much !!
I bought a new computer and having the same issues, now works like a charm
