I was using NoMachine to access Ubuntu 11.10 when suddenly the internet on Ubuntu stopped working. Now Ubuntu doesn't recognize the internet at all (including locally).
- Doesn't recognize the fact that there is an ethernet cable attached. (I've tried switching cables, didn't work.) GUI says "No network devices available"
Can't ping external IP addresses.
Tried changing /etc/network/interfaces to eth1 instead of eth0 but it didn't work.
ifconfig provides no output relating to eth0.
When I type "/etc/init.d/networking restart" it tells me "Cannot find device 'eth0'/Failed to bring up eth0."
The network settings had used a static IP address prior to the crash. I don't know why it won't recognize the ethernet (I think this is the fundamental problem, but I might be wrong) and why it stopped working so suddenly--I haven't installed any updates lately.
Any ideas? Any more information I should provide?
lspci recognizes the Ethernet controller; netstat does not. lspci calls it "Intel Corporation Device 0000". I'm not sure what this is SUPPOSED to be, because it seems kind of generic and that might mean it's corrupted--does anyone have any experience with corrupted ethernet cards?
