-96dBm isn't too bad. If you have a -65dBm signal, you get a 31 dBm signal-to-noise which is quite good. Be aware that that is measured at the AP. If you have an interferer close to the user, it may not be visible to the AP, but it may affect the user.
Just checked another AP here, that is is -92dBm noise floor.
Do you have the equipment to do spectrum analysis? Or heatmapping near to the problem area?
The same user in a different location does not have any issues?

Subject: VC Controller with Radio Noise at -96dBm
We have a VC Controller i535 AP, with about 23 other 535 AP's on 2 floors. The Dashboard Overview of the AP's show both radios Noise (dBm) level at -96dBm.
That seems elevated to me, but I cant find any docs that say what the range should be normally.
We are fighting with a small section of the second floor that has poor reception quality with 5G signal. The serving AP is about 25 ft from the CEO's office, and a Scan shows what looks like the radio [5G] having a strong signal in one direction, unfortunately away from the CEO's office. Offices are aluminum studs, insulation and drywall, nothing special.
Are there technical docs that show Power and dBm loss best practices?
Thanks
