I am stuck on chapter 10, “Arduino Ethernet Programming”. I have tried numerous things to get the Arduino to act as a server but it just won’t connect. I’m running Windows 7 on my PC and I have a Netgear router for my wireless router with 4 wired ports. I’ve plugged the RJ45 into the router and my PC and tried different IP addresses that are not taken by my router already but nothing works. I cut off the firewall once but that didn’t help. I replaced the Ethernet shield and the UNO but that didn’t help. I’m trying to run the simplest code as best I can tell which is the Monk example code 10-01 copied below for reference:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>// sketch 10-01 Simple Server Example<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>#include <SPI.h><o:p></o:p></p><p class=MsoNormal>#include <Ethernet.h><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>// MAC address just has to be unique.

I’m unplugging the USB as instructed in the book and plugging in a 9 Volt battery pack – all I have right now for power. I have a 9 Volt 1.5 Amp power supply on order to get here Friday. I’m not sure if that is a problem or not. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m running Arduino IDE 1.0.4.
