I am noticing this in one of my APs where I am having a lot of issues about some clients connected with old devices in 2.4GHz, having a poor quality:

Coverage Information
As you can see, the channel interference is at 4% bussy (AP is working in channel 6) but channel utilization is 82%, while TX and RX ispretty low. I am wondering about the reason of this, which could be the causes bechase there is a hich channel utilization while the AP is not seinding/receiving almost traffic, there is not interference detected and just 3 clients connected?
On the other hand, the interference by channel in the GUI looks pretty high in the same AP (as you can check in attached screen) so I am pretty confused about this values. Could you please help me to understand this values? Thanks!
Thanks.
