First, the Pi does not connect itself to the internet without SW telling it to do so. Generally, folks run the desktop and use one of the available programs like Netsurf or Midori. It does sound like your ethernet is not getting an IP address from your router. If you are using Raspbian Wheezy, you can edit file "/etc/network/interfaces" to set up the ethernet connection. It's possible that the current setup looks like this:
If so, try replacing the "manual" with "dhcp". If it is already set to "dhcp", then you may need to set a static IP address for the Pi. You will need to know the base address of your router (usually something like 192.168.1.1). Then you can set eth0 as follows:
Code: Select all
iface eth0 inet static
address 192.168.1.66
netmask 255.255.255.0
gateway 192.168.1.1
The "gateway" is the base address of your router and the "address" is the same except for a different last number.
