Well, whatever the problem was ,it did not affect the transfer of real time data between my station and the WeatherLink.exe Windows PC program fetching the data over our LAN. That stayed live through the event. Good to know, because I had feared any loss of service on Davis' end might shut everything down on my end, so far as the WeatherLinkIP dongle was concerned.
Does anyone have a mobile application (Android OS) which can show the same live data feed as the WeatherLink.exe program does from Windows? So far everything I have found and tried from Google's app store deals with showing archived data, and doesn't produce anything close to real time data.
