No network on 12.04 install

[Leslie Anne Chatterton]

Hi Hakan,

I would respectfully disagree. In diagnosing a problem we start at the
simplest point and work out from there.

If pinging localhost works then there is a valid IP address and the TCP/IP
stack is functioning properly. If pinging localhost doesn't return any
answer then that is where the troubleshooting has to start. There is no use
pinging anything else until this is working.

After that has been established as working correctly we move on to the LAN
and then the external sites. This checks on DNS etc.

If one jumps ahead and does the last step first and if it fails  then you
have to go back to basics anyway. Successful troubleshooting requires a
methodical and systematic method of approach. It took me years to learn
this and discipline myself to follow it consistently but it always works.
