YAY I GOT IT WORKING! I was connecting the ethernet shield through network sharing on my mac. I ifconfigged (yes that is a word  smiley) and found out that the ip address had to be Thank you so much for your help!  smiley-lol smiley-lol smiley-lol smiley-lol smiley-lol smiley-lol smiley-lol smiley-lol Sorry about the wrong category. I saw a few other ones in this category and just assumed.

What should I do to configure my router? I'm not trying to port forward or anything. Just on the local network.

What kind of router are you connecting the Arduino to? What have you done to configure that router?
I haven't configured the router at all, but, I don't know what my router is. My router is up in the attic and I don't really want to go up there now. I tried three more ip addresses and none worked.

The web server Example:
  Web Server
 A simple web server that shows the value of the analog input pins.
 using an Arduino Wiznet Ethernet shield.
 * Ethernet shield attached to pins 10, 11, 12, 13
 * Analog inputs attached to pins A0 through A5 (optional)

The serial monitor should print client connected when I go to

I began debugging the program. Then, it stopped working. I loaded the example up (which in the new version of arduino includes the serial debugging) and on the serial it only displayed
server is at
Thanks for responding!

My near-brand new ethernet shield isn't connected to the internet. I have the basic web server running. When I go to the ip address, the server doesn't respond. The serial monitor doesn't display anything either. The link and 100M less are always on. I had it working a couple hours ago, but, suddenly, it mysteriously stopped. Thanks in advance. smiley

Here's a vid that I made on how to make a pumpkin that senses if a person puts there hand in based on the capacitance of the person's hand.
