hello guys i got a big problem i got a arduino uno and a Ethernet shield for the same when i plug the arduino uno and the shield together then when i plug the ethernet cable from my router only the FULLD led is blinking and there is no lights in the Ethernet port side of the auduino as shown in the images please help is there a problem in my arduino or there is a problem in my shield
Excuse me but the shield on the photos is not an Arduino Ethernet Shield but some Chinese copy. Many of these are not properly working, sometimes because of bad soldering, sometimes because of fake chips. This is probably not a problem of your Arduino but of your Ethernet shield.
I have a chinese clone ethernet shield (with chipset w5100) and have managed to get it working using a powerline homeplug. It does not work successfully with gigabit switches or many routers. It should also work well with an older type of ethernet switch (10/100) which you may be able to get secondhand on ebay. If you google the problem you will find a lot of articles on the problem.
AssaultKing:
there is no lights in the Ethernet port side
While your post is more or less unreadable, the above might suggest the lights in the RJ socket, which I believe only come on when the port is active. In that event, there may be nothing wrong with the Ethernet shield, and quite a lot wrong with your code.
You are presenting us with very little information.
Is it a R3 uno and a R3 ethenet shield or ????
Lets see your code and maybe the serial output if any.
BTW: Don't be afraid of chinese clone shields. I have been using several without any problems.
