Interpreting Spectrum Analysis

Hi, I just want to make sure I am correctly understanding the readout of the spectrum analysis feature on ZD. What does a 'bad'/''good' reading look like?

Here's an example from one of our APs

Thank you!

Good/bad is subjective.  Your shot shows typcial 2.4g bandwidth utilization, channels 1 and 11 a little hotter than channel 6.
Are you having any AP reboots or client problems on this AP?

There are reports of issues at the site that this AP is deployed at, and I wanted to make sure that channel utilization wasn't an issue.

Usually you will get issue can't connect to WiFi, this is because issue channel ultilization from device is -65db or above. So recommendation is stay in 1-65db
