When I connect my Samantha Module to my NXT, the NXT shows the wrench icon When I connect my Samantha module to my NXT, it shows the wrench icon instead of the USB icon. 

I have tried updating the firmware, to no avail. 

The blue light does not turn on. It sees the WiFi network just fine, the white light flashes, but it will not connect to the NXT. 

Any ideas?
