Raspberry Pi Ethernet Problem

Hi Eric,

You say you have "checked all the network items", but you don't say what these are or how you checked them.

Are you using an ehternet cable to connect the Pi into your router, or are you trying to use a USB WiFi dongle?

If you are trying to use WiFi, get an ethernet cable and use that first.

If you are using a cable are you plugging it directly into your router or into a separate switch?

What is the router you are using?

Have you tested your ethernet cable with another device, like a laptop, to make sure it works OK?

It uses a wired connection. I have ran other computers on the same hub port with the same ethernet cable and they connect to the internet without a problem. I have tried connecting the raspberry pi directly to my cable modem using the same cable that was tested with other computers and still the three network lights on the raspberry pi just blink repeatedly without connecting.  What would cause all 3 lights to blink? 

Ah, cable, do you have a separate hub connected to the cable modem? Or does the cable modem have a built-in hub?

When you connect the Pi to your hub and power it on, does the hub port light come on?

We also need the answer to Gary's question. Open a Terminal and type:

ifconfig

Then post us what the terminal replies.

You should see something like this:

I see the following when I do that:

eth0

Link encap:Ethernet HWaddr b8:27:eb:d7:43

UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

I do have a hub connected to a router connected to a modem but the same result happens when plugged in directly too.

I could not see eth0. and it is disabled since yesterday only before it was connected. How to enable this. Please help resolve this issue. Thanks in advance
