I just updated my laptop from Ubuntu 12.04 to 12.10. After the update I could no longer get to the login screen, and after a while I realized that during the update my nvidia-drivers had been uninstalled. Apparently no other graphics driver is available.
So I started a root prompt to install nvidia-current only to find out that my internet connection is gone. I did the whole update with an ethernet cable plugged in, so it obviously worked in 12.04.
I tried to run /etc/init.d/networking start
and service networking start
to no avail.
ifconfig -a
only shows the lo
interface (Local Loopback).
lspci
lists my ethernet controller:
04:00.0 Ethernet controller: Atheros Communications Inc. AR8151 v2.0 Gigabit Ethernet (rev c0)
I found some resources on the net suggesting I add
auto eth0
iface eth0 inet dhcp
to /run/network/interfaces (which didn't exist), so I did that and retried service networking start
. However, it still doesn't work.
How do I make Ubuntu 12.10 recognize the ethernet connection?
Edit: I just ran lshw -C network
which lists both my ethernet and wireless as UNCLAIMED. I heard this means there are no drivers available. I have a USB-drive with 12.04 on it, can I somehow extract the correct driver from there and install it?
