W5200 Ethernet Shield BUG?

Update 02-01-2014:
I was a bit to fast with my previous reaction, it is now sometimes working, and sometimes not. Sometimes it has the correct IP, and sometimes it I get the IP 255.255.255.255 of 0.0.0.0.
Is this due to the hardware bug? I'm not really happy to start breaking the connection before I have the acknowledgement, but I cannot find anything else on the internet about this hardware bug, accept on the wiki site of Seeedstudio.
Is there some one with the experience of using this shield with or within breaking the connection mentioned on the wiki site?




Update 29-12-2013:
I just found out that the ports on my modem are not working right, after replacing the modem it all works fine!
I'm still wondering if any one knows more about the BUG mentioned on the wiki site. If any one has some input about this, please let me know.

Dear all,

I have bought the W5200 Ethernet Shield on 11/11/2013. I'm trying to connect the shield via LAN. I have inserted a Mirco SD card of 2 GB, connect the lan via my router. and loaded the example from the library (Ethernet V2_0) "Web server with SD". I'm able to read the output via serial-monitor, and I get the following output via serial:

Code:

Initializing SD card...initialization done.
Writing to test.txt...done.
test.txt:
testing 1, 2, 3.
testing 1, 2, 3.
testing 1, 2, 3.
server is at 255.255.255.255

Whatever I try I keep getting the IP adres 255.255.255.255. Even though in the program it is stated:

Code:

IPAddress ip(192,168,1,100);

Can any one help me, is this due to the bug mentioned in the wiki site? http://www.seeedstudio.com/wiki/Ethernet_Shield_V2.0

Quote:

The Ethernet Shield V2.0 has a bug which makes Ethernet Shield V2.0 work not normally. We made this processing for this problem: Break the connect between the 74VHC125PW 2pin and W5200 45pin: WPDN.

I did not break the connection on my board, at this moment.

Any help is welcome!
