Arduino Leonadro with w5100 power problem
i useing arduino leonadro w5100. works computer usb port. when use mini usb port via 5v 1a or 2a
or dc 9v 600ma , arduino ethernet shield did not work! , leds on etherner shield seemed right,but when go router management page , can't see arduino has been connected router. use arduino server.what's problem it? how solve it?
thanks!

can tell more ?
i assume normal ethernet shield, uses 5v arduino leonardo , makes own 3.3v.
connected usb computer working ?
whap happens when use 9v power supply barrel jack of leonardo (or vin) ?
it possible use 5v power supply, first have measure if 5v. did connect usb micro connector ?
the ethernet shield requires amount of current. when have bad connector or cable thin wires or breadboard bad contacts, voltage drop. can measure 5v pin of leonardo. if 5.0v (or @ least 4.8v, perhaps 4.5v) okay.
