Hi Tchernyavsky. This sounds like a common problem with the early ethernet shields. See http://forum.arduino.cc/index.php?topic=25634.0
Hi ThomasF5,The key you've provided in the above example is only 31 characters, but should be 32 characters. Your problem was likely caused by a simple copy/paste error. I would recommend you register for a new key because the one you've displayed above is now public knowledge on the internet :)
Hi noel.kuck,This would be the expected behaviour if you hadn't restarted the Arduino software after installed the library. Hope that helps!
Hi Bladder777,I'm currently testing a version of the sketch for wifi. I'll get in touch with you to help you out.
