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:
ifconfigyields an entry for lo and some virtual ethernet bridges, but no eth0 nor wlan0.
NetworkManager Tool State: disconnected
auto lo iface lo inet loopback
lshw -sanitize -C networkyields:

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
[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.
