title: Raspberry Pi Ethernet not connecting
body: <p>I have just installed Raspbian on my Raspberry Pi and I booted it up with it attached to a monitor, keyboard, and ethernet. I can successfully log in, but when I run ifconfig, it only shows the lo interface (eth0 does not show up at all). It is plugged into the router via ethernet and the lights by the ethernet outlets are on for both the router and the raspberry pi. It also does not show up as a connected device on the router admin screen.</p>
  
  <p>Since this is a new Pi, I'm not sure if the problem is hardware or software, do I need to do anything special to connect it to ethernet?</p>
