After upgrading to 13.04 I can't make wired connection work (wireless internet works fine). I checked in connection settings that it's supposed to connect automatically.

ifconfig gives:

The only solution that kind of worked for me (which I found in similar questions to previous releases) was adding to /etc/network/interfaces the following lines.

auto eth0
iface eth0 inet dhcp

But then whenever I boot without wired connection I get problems with network configuration and have to wait a long time before the system starts.

I understand that the problem is with my e1000e driver (correct?) but I'm not really sure what I could do about it. I appreciate any suggestions.

chili555, many thanks for your reply. The solution works for me. Apologies for not finding it on my own and once again thank you! –  trontrytel May 8 '13 at 17:38
    
Glad it's working! Have fun! –  chili555 May 8 '13 at 19:47

1 Answer 1

Try this

echo on | sudo tee /sys/class/net/eth0/device/power/control

This should definitely solve the whole problem...after its done, exit sudo and pull out, then plug in the ethernet cable again
