maybe try removing "IRQ" connection? as its not needed.

also i had the some issues, but i had my wires mixed up..

Hi mfalkvidd,

Thank you for the quick reply, appreciated the help.

Arduino Uno3 with a generic ethernet shield on it, which i picked up at local computer store. I have the Arduino powered via a 5V 2A (2000mA) switching power supply which connects directly to wall outlet.

I dont have the serial connected. As you know, i wanted the device to power via wall outlet. So I dont need to connect the USB Serial. But you are right, this would be a good step to troubleshoot issues. However i didnt want my computer plugged in for long time, as i have other projects im working on

But i can connect Serial and watch output. The only issues it i think it takes few hours before Arduino becomes unresponsive.

Hello all,

Im having some issues with my code. It works great, but only for a few hours. Then device disconnects/unresponsive. Hope someone can give me some advice on my code. I created this device to control my TV. Thank you in advanced and appreciated any advice.
