I do not manage to send data using the Matlab exemple for wifi. I have no problem using the Ethernet shield.
The program is correctly deployed on the arduino and the connection is working. The green led link in on and when i try to ping on the IP it works.
Using the Simulink host model: TCP/IP Host Send, when I clic on verify dress and port connectivity it says that the adresse is recognized but not the port.
Can somebody help me please.
Best regards.

Hey, I had a similar issue with the Wifi shield. After deploying the program to the Arduino, the Green LED LINK lighted up. However, when I tried pinging / verify port connectivity it would fail.
What I did was to upgrade the Firmware on the Wifi Shield: https://www.arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading and now it works fine.
