There seems to be a problem with my network drivers. Neither eth0 nor wlan0 are recognized, and I'm running 13.04 over the 3.8.0-27-generic kernel.

Here's some diagnostic information:

  1. ifconfig yields an entry for lo and some virtual ethernet bridges, but no eth0 nor wlan0.

  2. nm-tool yields:

    NetworkManager Tool
    
    State: disconnected
    
  3. cat /etc/network/interfaces yields:

    auto lo
    iface lo inet loopback
    
  4. lshw -sanitize -C network yields:

    PCI (sysfs)

What I've tried:

I tried to connect the NetworkManager Tool. From other sites, I've seen that it sometimes helps to change the file /etc/NetworkManager/NetworkManager.conf from:

[main]
plugins=ifupdown,keyfile
dns=dnsmasq

[ifupdown]
managed=false

To:

[main]
plugins=ifupdown,keyfile
dns=dnsmasq

[ifupdown]
managed=true

And then doing a sudo service network-manager restart and/or rebooting the machine, but that has not worked either.

Any other ideas? Many thanks.

It might help to add info about your network devices e.g. the output of sudo lshw -sanitize -C network –  steeldriver Sep 28 '13 at 23:16
    
Updated, thanks. –  Cody Sep 28 '13 at 23:54
    
What ethernet bridges? Is this running in a virtual machine? –  chili555 Sep 29 '13 at 3:37
    
No, this is in the host. I have a couple of ethernet bridges that I use for some virtual machines (using lxc). –  Cody Sep 29 '13 at 20:49
