Hi all. Sorry for edit i accidently click to save button. my problem is : I start a project and i can't solve this issue please help me. I have arduino and ethernet shield and i get temprature from arduino and write this value to my own server. It works very well and stable on my home internet. i want to run this project with blocked router(like routers block to enter youtube ...etc). i tried this project some blocked internet and they works fine. But i tried some router and getting me 0.0.0.0 ip and can't connect to internet. i tried everything. Change different library, set static ip, use another arduino with ethernet shield everytime arduino serial getting me this and can't work. i tried this router with my pc it works well but arduino doesn't. Any ideas or solution for this issue. Thanks for help.

Please post a link to where you bought the Ethernet Shield from. A frequent cause of problems when using the Ethernet shield is using a library that does not support the Ethernet controller chip on the shield.

OK, if the shield worked correctly on one network then the problem is definitely not caused by using an Ethernet library that does not support the Ethernet controller chip on your shield.

My problem is still continues. i tried everything again and still router don't give me an ip adress. i look internet properties in my pc i see DNS suffix adress (Ex. asdasd.com). can i give  manually DNS suffix on arduino?

Makes no sense.
i try to use this arduino like university or goverment like internet router. Router block some website like youtube, game website etc... When i tried to connect network through this router this router can't give me ip adress and for that reason i can not connect to internet and send data. In this router if i plug same ethernet cable to my pc network give me access to network and very stable. i cannot figure what's the problem. But when i connect this router from my pc i see something different in ip properties Connection-specific DNS Suffix: blablabla.com.

Different routers. Different behaviors. I suggest you read about the 511 ohm resistor pack problem with the W5100 shields.
