I just put in 2 AP305c's in my building & keep getting . wifi0: A high interference alert was raised alarms randomly on both. I noticed that several were getting same error on the 250's as well. Is this a known issue? Im on latest firmware.

Thank you for that tech data. I'm seeing a high CRC failure rate for both wifi0 (32%) and wifi1 (72%). That means that 32% of the wifi0 traffic and 72% of the wifi1 traffic is too damaged to read and had to be resent at least once (likely more than once) before the receiving radio could read the packets and move on to the next. CRC failures in particular are usually caused by environmental factors. Could you send me pictures of a few problematic APs so I can check for environmental factors that may be interfering with your signal?

I am attaching tech data for this question.

This guide reviews how to identify if your network has a high level of Radio Frequency Interference: https://thehivecommunity.aerohive.com/s/article/Radio-Frequency-Interference-NG

If you'd like to send tech data from an AP having this issue to me at communityhelp@aerohive.com, I can review the data for you to let you know what I find.
