Networking no longer working on Ubuntu.

[doctorgenesis]

Ok, first of all the computer was 'killed' (the switch to the outlet my PC is on was cut off). After that I turned it back on, alas networking no lonber works, even with ethernet. Everything online is not helping and when I go to recovery menu dpkg doesn't work as it can't connect to the net.

-mm        Produce machine-readable output (single -m for an obsolete format)
-t        Show bus tree


Display options:
-v        Be verbose (-vv for very verbose)
-k        Show kernel drivers handling each device
-x        Show hex-dump of the standard part of the config space
-xxx        Show hex-dump of the whole config space (dangerous; root only)
-xxxx        Show hex-dump of the 4096-byte extended config space (root only)

Oh PS; when entering enable networking under recovery mode it shows this in the prompt;

Grep: /etc/resolv.conf: No such file or directory

[wildmanne39]

We need to see the output of:

lspci -nnk | grep -iA2 net

please just copy and paste for accuracy.

Thanks
