I have a headless Raspberry Pi using Debian Wheezy.
I have a wifi dongle and if I connect my Raspberry using it, everything works fine: I can connect to the Internet, I can ping, I can update.
However, if I get down my wifi and set up the lan interface, I lost my internet connection.
I still can connect to it locally, using my laptop, but the connection doesn't exit (ie ping is not working).
Some useful info:

well, I think that's all... Any ideas?
I checked EVERYTHING and finally I found the reason: my electrician created TWO separated LAN without telling me. I was plugging the cable in the wrong plug. Now I know how to workaround on it (and do a little talk with my electrician...) – tampe125 – 2013-07-05T10:03:18.703
