Noticed the Network Diagnostic bar graph on Poor (Red) with many dropped packets reported - 72% over time. Audio and signals on the pan adapter were normal. Spent a few hours diagnosing the problem - New Patch Cables - New switch and on and on - connected Wireless . Well this morning used the Maestro via Ethernet and all bars were green - So it hit me that a Windows update was installed yesterday. Update KB4015217 was in fact installed - So I uninstalled it to see how things would go. Upon reboot after uninstallation, I have 5 green bars-solid all is well. Flex may need to tweak something due to KB4015217 if they can duplicate the issue. Wanted to throw this out in case others are seeing the same issue.
