AP350. This is interface wifi1 and has very high floor noise and interfernce utilization shown as below:

Rx airtime=512.89 ms; Tx airtime=2.41 s; CRC error airtime=4.70 s;

Rx airtime percent=0.03%; Tx airtime percent=0.50%; CRC error airtime percent=0.03%;

Tx utilization=1%; Rx utilization=0%; Interference utilization=17%; Total utilization=18%;

Backhaul failover=disable;

Running average Tx CU=0%; Rx CU=0%; Interference CU=1%; Noise floor=-15dBm;

Short term means average Tx CU=1%; Rx CU=1%; Interference CU=8%; Noise floor=-41dBm;

Snapshot Tx CU=1%; Rx CU=1%; Interference CU=9%; Noise floor=-45dBm;

Would you be able to send me tech data from an AP with this issue? This guide reviews how to get tech data in ExtremeCloud IQ: https://thehivecommunity.aerohive.com/s/article/How-to-download-tech-data-in-HiveManager

If you'd like to send the data to me, please feel free to send it to communityhelp@aerohive.com.

Thank you for that tech data. I see one neighboring signal that is very loud and is not coming from an Aerohive AP. It looks to be a Netgear device with a MAC address that starts with: b039:5663:db

I would recommend finding that device and disabling it or at least turning down it's broadcast power.

Additionally you have a high rate of CRC errors on both radios. I would recommend going through the troubleshooting outlined in this guide: https://thehivecommunity.aerohive.com/s/article/Radio-Frequency-Interference-Troubleshooting
