iMX233-OLinuXino-MINI-WiFi: wireless module doesn't work

[83dani83]

I bought 2 cards iMX233-OLinuXino-MINI-WiFi, with two-iMX233 OLinuXino-SD.
Nevertheless, The WiFi module does not work and is not detected between devices.
Also, are only two of the three serial, one of which is for debugging.
I bought this card for Wi-Fi and to have at least two serial ports, how can I do to solve these problems?

Thanks!
