@PhilipDAth Thanks, I suspect then that with 8 devices, the system could not find 3 channels that worked for all 8. I have now turned on 6 of the 8 APs and left 2 of them off. I had to force 1 AP to go to channel 6 to get the separation I wanted (no circles on the same channel overlapping) and then I set it back to auto and clicked on update auto channels and it keeps wanting to put that AP on 11 which causes the overlap of circles with another AP on 11 very near by. So for now I forced that 1 AP to channel 6 and it seems to be working, no overlapping and no high utilization.
