The NetX can get confused if things go wrong during its configuration. Try resetting it to the factory settings by pressing and holding its Config button for 10 seconds. Then try again. In busy Wi-Fi networks it may help to shutdown other Wi-Fi devices during config. Also be sure to have the NetX physically close to the iPronto as it communicates directly with it - NOT via the Wi-Fi Access Point - during the config operation. (After config it does revert to comms via the WAP)
