I just received my WS-2000 yesterday and went through the setup step by step.
It is not uploading the ambientweather.net however.
I have confirmed the MAC address on both the console and the web.
I reset the tablet and rebooted my router
Upper left corner of the tablet show the WIFI Icon but not the Ambient Icon. The Ambient Icon was showing at first.
I have not tried WU yet as I have it running elsewhere.
Anything else I should try?
