Using Arduino UNO and WIZ550io - crashes when using ethernet.begin(macData)

Using Arduino UNO and WIZ550io - crashes when using ethernet.begin(macData). Using ethernetreadwritestring example. Can not ping WIZ550io. Connected to switch along with PC and connected to cable modem. Trying to send data to exosite site. If I comment this out, the serial monitor will display: Connecting to Exosite...Connected Error: HTTP Response Timeout Error Communicating with Exosite

Post the code or a link to that example code.

Jabraham, that example is for the Ethernet shield. Is that module interchangeable with an Ethernet shield?

This is the example: https://github.com/exosite-garage/arduino_exosite_library/tree/master/examples/EthernetReadWriteString

Had wire for MOSI and MISO crossed.

In the program revised: Ethernet.begin();

Works ok now...
