I shut off the router and left Wi-Fi up and discovered Hub A continued to transmit UDP data but Hub B stopped transmitting UDP data. Once WAN was restored, Hub B started transmitting UDP data again.
Archiving RapidWind data actually does have a benefit.
You can see this in the data captured which is sorted in ascending order (newest on top for you Steeler Fans)
This confirms the previous bug where the data from devices is not sent via UDP
