I bought this shield and plugged it on my arduino mega. I noticed some problem with the serial communication so I tried to use SPI using the library provided by WizNet (github.com/Wiznet/Arduino_WizFi250.git) which uses SPI and it has way more options and better command.
I’m asking this to the developer or designer of this board:
Why in the world did you left the MISO pin from the wiznet chip (pin 21) not connected??!!!
From the schematics it seems that the pin from the wiz chip is connected, but on the board file and in the reality it is not!! All the other pins fro SPI are connected (MOSI, SCLK and CS) but the MOSI not!!!
