You have something nearby that is causing interference. Try changing the channel to see if that helps, the problem could very well be coming from a neighbor.

Maybe, a diagram separating RX, TX and Interferences would help people from mis-interpreting displayed figures.

In my case, I'll change radio settings in 2.4 GHz band (selecting different channels instead of automatic, lowering TX power), the one showing a high TX figure, in nearby APs to see if RX figures significally change.

I'll repoprt my findings here.

Here, AP are about 6 to 8m away from each other, in plenum space over ceiling tiles, in straight corridors in a multi stage.

In one floor, I couldn't detect any AP from above floor so I hope little inter-stage interference.

I often alternate 2 channels in a given corridor and use a different channel pair when crossing a perpendicular corridor.

Due to lack of time, almost all AP are currently left with Auto settings.

Hi  @Chaotix 

 

The utilization displayed on this interface does not refer to the EAP's wireless utilization rate or other metrics. Specifically, it indicates the channel utilization rate of the current band's operating frequency.

This value reflects the real-time wireless environment status of this EAP, and has little correlation with the number of connected wireless clients.

We would recommend that you try to switch to other channels to see if it improves the situation.
