Raspberry Pi Ethernet Problem

In that case it seems that the network device is OK. Try manually setting the network configuration.

Use your favourite editor on /etc/network/interfaces file. Make sure it looks like this:

auto eth0

iface eth0 inet dhcp

If that works, you should be good to go. If that doesn't work then set the IP address manually, you need to know the subnet, usually 192.168.0.0 or 192.168.1.0, and your router IP address,

auto eth0

    iface eth0 inet static

        address 192.168.0.55

        netmask 255.255.255.0

        gateway 192.168.0.254

If this works you should have network connection, man interfaces should give you more information on this file should you need it.

This will test whether you can get a network configuration loaded. If you can then se if you can ping your router.

I tried both. By setting it to DHCP, upon reboot it just searched several times for an IP address but never got one. I tried to ping once it rebooted and nothng. I also tried setting a static IP as you said and nothing for a ping still. Perhaps something is physically wrong with the ethernet port?

That is possibility, but more likely it is your ethernet cable. Test that on a workimg system just to discount it.

Also try one of the other distributions or an updated copy of Raspbian from here http://www.raspberrypi.org/downloads

(you didn't say what version you were running).

Also check your router is actually sending DHCP out on the ethernet port (you didn't mention what router you had).

If you have managed to configure a static IP address properly can you post the output of ifconfig please. Also can you ensure that your chosen IP address is on the same subnet as the router (sorry if this is basic stuff, but I don't like to make assumptions about your experience level as you haven't said).

Another trick is to connect another device into the wired network and try that out. Once you have a working connection on that device try connecting to the Pi or vice versa. It would be useful if you could also post the output of ipconfig /a from any Windows device you have connected, or ifconfig from a Mac or Linux terminal session on the other device.

Ethernet ports are usually quite reliable. Mostly it is bad cables, dodgy DHCP configurations or problems with the arbitration of a connection speed with the switch/hub. On that subject what is your switch/hub (manufacturer and model)?

Please also list your IP address configuration for the internal network of your router, Pi and other wire connected computing device, just so we are clear that everything is OK.
