Currently, I have no issue with POE, hence why I am cautious. When the C8's first came out there seemed to be an issue that affected POE using Unifi gear. I think as think as things unfolded it became a more generalized thing, but unifi still seemed (at the time) to be at the center of the issues PoE and the C8 (with extensive testing)
I believe the yare both upto date, neother is showing a update available.
Where is this setting at? I can't seem to find it. Though I am not sure it matters , i have a pretty solid wifi heat map across the house (the router is located in the front of that Flex Space/office off the garage).
The control Channel is 6, My Zigbee (that little I have, only 4 devices) Zigbee is channel 25. Im working on retiring the last few Zigbee devices in the next few months.
