Hello. I changed the length of the LAN cable that goes to the Ethernet Shield with 50 cm to 10 m. It is also changed all the wires that go to the Ethernet. Could it like that affect the way that the MAC address has become zero and the server is not available? Diodes, relays connected to the Ethernet works. But Page 192.168.0.33 (page server) is unavailable and the MAC address 00:00:00:00:00.
It still works if you use a 50cm cab;e, but fails with the longer cable? Are you certain the cable isn't faulty? Which Wiznet IC does your shield have? Is the new longer cable a crossover cable?
Where are you seeing a mac of 00:00:00:00:00? Maybe you should post your code.
UTP cabel, link Патч-корд UTP кат.5e 10м Серый — купить в городе РЯЗАНЬ Sorry, but the site is in Russian. About crossover nothing written. Null MAC address I can see in the router settings, displaying connected to the router device. What Wiznet IC? With short cable working all. And with the cable I bought did not do?
Then I don't know what to tell you. If it works with a short cable, but fails with the long cable, then it must be the long cable at fault.

I understand, to connect the Ethernet Shield with a router need a crossover cable? It turns out that the short cable crossover?
Not normally. It depends on the router though. If you connect the shield directly to a computer, you may need a crossover cable. That depends on the capability of the computer's ethernet card.

I connect the cable directly to the router and the Ethernet Shield. A short cable works, a long cable not working. Which one is the Crossover?
I don't know about that, but I can tell you one thing.
The short cable works.
The long cable doesn't work.
edit: Can you see the wires where they enter the connector at each end of the cables? If the wire colors are in the same order on both ends, it is a standard cable. If they are not, it is a crossover cable.
The colors are arranged in the same order. Why, then, does not work? Long cable only yesterday bought. Left long cable, the right short.
Are they the same on each end? Check both ends of each cable.
Both cables are the same at both ends. Maybe it's in the length of the cable?
Could be the length, or a bad connection or short in the long cable.
Thanks for the help.
