My last installation of Ubuntu 12.04 on a machine using an ASUS Q87M-E motherboard with an Intel I217LM Ethernet controller has failed to detect the ethernet card. The only thing displayed by

ifconfig -a

is the loopback. I double-checked in the BIOS, and the controller should be online.

I'm pretty stumped at this point. This doesn't sound like a very uncommon ethernet controller and I figured it would be picked up by the system.

Does anybody have advice for how to deal with this? Anything specific I should look into to figure out what could be causing this?

Edit:

It seems that following the guide on the Intel e1000e drivers page allowed the card to start working. Is this a real fix or is there a better way?

Can you run an "ifconfig" and post the output of it? –  seanthewebber Jun 20 '13 at 4:24
    
Of course, updated the post with the output. –  Alexandr Kurilin Jun 20 '13 at 4:34
    
Oh boy.. run an "rfkill list all" and tell us the output. –  seanthewebber Jun 20 '13 at 4:38
    
Updated the post with rfkill list all! Please note that the wireless controller is just a usb dongle I'm using right now to "bypass" not being able to connect through the wire. –  Alexandr Kurilin Jun 20 '13 at 4:57
    
Mm.. Ubuntu doesn't detect it yet it does.. are there any other OS's on the machine to test the Ethernet with? –  seanthewebber Jun 20 '13 at 5:02

This appears to be a real fix.

I had the same problem today and found the explanation: support for Intel I217 is available since linux kernel 3.5 (commit). As Ubuntu 12.04.2 uses kernel 3.2.x, the Ethernet card is not recognized and cannot work.

I followed your advice and installed the e1000e driver from the Intel e1000e drivers page and it worked perfectly. From there I was able to upgrade the linux kernel.

That's awesome, thank you for investigating this further!! I was still puzzled about what was going on there until your explanation. Hopefully this is of help to people stumbling into the issue in the future. –  Alexandr Kurilin Jul 3 '13 at 18:31
    
So this ethernet I217 worked with e100e driver just fine? I cannot upgrade kernels due to software limitations, and I need to use a new system with this hardware. –  dbbd Dec 16 at 13:07
    
@dbbd Once I installed the e1000e driver from the Intel site, it worked perfectly. I could continue to use this configuration (not upgrading the kernel) but I needed to upgrade. If you follow instructions on the e1000e page to compile the driver and load it, it should work as expected without upgrading the kernel. –  cbliard Dec 16 at 14:30
