No Ethernet with Asus Prime Z270-A

[LinuXXuniL]

Hello!

I've just build a new desktop PC with Asus Prime Z270-A motherboard and I do not have internet access, looks like there is no driver for it.

Is there a way to manually install the driver for Intel I219-V Gigabit LAN?

Thanks!

The necessary driver is included in all recent Ubuntu versions by default. If it didn't load as expected, there is some other problem. Please open a terminal and run and post:

lspci -nnk | grep 0200 -A2
lsb_release -a
dmesg | grep e100

Thank you for your fast reply!

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

As you can see, the correct driver, e1000e, attempts to load, encounters an error and bails out. That's the 'something else is wrong' that I suspected.

The fix is a bit complex: http://superuser.com/questions/11045...el-ethernet-co

Before we get out the plasma cutters and go full geek mode, let's take a gamble that the newer driver in 16.10 might possibly work properly. Please download the 16.10 image, make a USB or DVD and try a live session. If the ethernet works, install it and we're done! If not, check again:

dmesg | grep e100

If you get the same message about NVM checksum, we'll install the later driver after we amend it a bit.

The code fix isn't in linux-next, in 4.4 source code look around line 7143 for the problem

Yep. I hope this will compile on the OP's 4.4 kernel. It does not on my 4.8 due to, I understand, gcc incompatibilities.

Hey, thanks for your replies!

I had a look on that discussion though it is a little too complicated for me to fully understand.

As jeremy31 pointed, the problem is not dependent of kernel, it is really an error in the NVM Checksum, very annoying and I am really interested to solve this on a hard way but I will need your help cause I really don't know where to start it.

Anyway for a fast workaround and assuming the risk I've done this using bootutil:

"chmod +x ./bootutil" "sudo ./bootutil64e -NIC 1 -defcfg"This made my LAN functional and I am able to access the internet now.

On the other hand I am interested in how to solve this in a none risky way, can you please let me know what should I do?
Do you think I should buy a new Network card as well as a backup?

Thank you in advance for your help!

Hi,

it seems we have the same problem on the German Forum:

https://forum.ubuntuusers.de/topic/k.../#post-8791278

I prepared the patched driver. Please find it attached with the amendment shown there in yellow (attached)

I'm not at all sure that the method you used is risky. After all, it is outlined on Intel's own site: http://www.intel.com/content/www/us/...000005790.html

My suggestion is to use it and not worry. I see no evidence that it is likely to revert. Hasn't it survived a few reboots?

If you feel uncomfortable, PCIe gigabit cards are relatively inexpensive, so a backup may be a good investment.

Thank you praseodym , if it ever happens again I will used the patched driver!

Hey chili555, it survived multiple reboots and is still working. Thank you for your help and advises, will put them to good use!

See you around!
