[App_rpt-users] RPi 3 controller problem

[Steve Zingman]

Bill,
Thanks for a complete description of your system, that helps a lot.
I did see Bryan's response about Wifi. I would say it's possible. Maybe 
a sustained ping to see if it's dropping packets.
Do the dropouts happen on inbound network transmissions or receiver 
input or both?
Since you are running SNMP, how is the CPU load?
Which channel driver are you running?
