I'm pretty new to the arduino scene, so this maybe a dumb question ...
I have an Arduino running with an Ethernet shield connected.
All works well, and i can connect to it at 192.168.1.200 on my local computer (this computer also holds the usb connection to the arduino board for uploading).
However if i disconnect the USB, and use an external power supply, i can no loger connect via http !
The project also has an lcd connected to it, so i can tell it is working when i"m running on external power, just no http support.
Remark : when the USB is connected lo my local PC, I can load the http page, but when i try from a differen pc, no luck. It only works on the PC that has the USB Connection.
The power supply can give 2amps, so no problem there i think.
And also, I can only connect via the browser on the PC that holds the USB connection, Not from any other pc in our network. and no, i dont think it is a network problem
If i connect the arduino to another PC via usb, and connect the ethernet cable, i can again open the http page on the new PC, but no longer on the old PC ....
Sounds like a network problem if you can only connect to it from the same computer.
What voltage is the power supply? I had a 5V for mine the first days, and my wishield was a bit unstable with it. (recomended voltage is 6-12V) And got rock stable after putting a 6.7V power supply on.
But try checking the network again, it should work from every where.
