I have an Cisco 3504 WLC, But my 9120 shows 0 in the Air Quality counter(Check pictures), but my 3802 is showing 98 in the Air Quality counter(Check pictures), what could be wrong?

Hi @ChristianSchmidtJosiassen

Air Quality is taken by the CleanAir feature. Make sure you have it enable for this AP.

Configuring Cisco CleanAir on the Controller

Configuring Cisco CleanAir on Controller (GUI)

Procedure

Step 1

Choose Wireless > 802.11a/n/ac/ax or 802.11b/g/n/ax > CleanAir to open the 802.11a (or 802.11b) > CleanAir page.

Step 2

Check the CleanAir check box to enable Cisco CleanAir functionality on the 802.11a/n or 802.11b/g/n network, or uncheck it to prevent the controller from detecting spectrum interference. By default, this feature is in disabled state.

Step 3

Check the Report Interferers check box to enable the Cisco CleanAir system to report any detected sources of interference, or uncheck it to prevent the controller from reporting interferers. By default, this feature is in enabled state.

Note

Device Security alarms, Event Driven RRM, and the Persistence Device Avoidance algorithm do not work if Report Interferers are disabled.

Step 4

Check the Persistent Device Propagation check box to enable propagation of information about persistent devices that can be detected by CleanAir. Persistent device propagation enables you to propagate information about persistent devices to the neighboring APs connected to the same controller. Persistent interferers are present at the location and interfere with the WLAN operations even if they are not detectable at all times.

Step 5

Ensure that any sources of interference that need to be detected and reported by the Cisco CleanAir system appear in the Interferences to Detect box and any that do not need to be detected appear in the Interferences to Ignore box. By default, all interference sources are detected. The possible sources of interference that you can choose are as follows:

Bluetooth Paging Inquiry—A Bluetooth discovery (802.11b/g/n only)
Bluetooth Sco Acl—A Bluetooth link (802.11b/g/n only)
Generic DECT—A digital enhanced cordless communication (DECT)-compatible phone
Generic TDD—A time division duplex (TDD) transmitter
Generic Waveform—A continuous transmitter
Jammer—A jamming device
Microwave—A microwave oven (802.11b/g/n only)
Canopy—A canopy bridge device
Spectrum 802.11 FH—An 802.11 frequency-hopping device (802.11b/g/n only)
Spectrum 802.11 inverted—A device using spectrally inverted Wi-Fi signals
Spectrum 802.11 non std channel—A device using nonstandard Wi-Fi channels
Spectrum 802.11 SuperG—An 802.11 SuperAG device
Spectrum 802.15.4—An 802.15.4 device (802.11b/g/n only)
Video Camera—An analog video camera
WiMAX Fixed—A WiMAX fixed device (802.11a/n/ac only)
WiMAX Mobile—A WiMAX mobile device (802.11a/n/ac only)
XBox—A Microsoft Xbox (802.11b/g/n only)

What version of AireOS are you using on the WLC?

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd21996
Fixed in 8.10.185.0 - but if you're updating then use 8.10.185.3 (link below)

Sorry for the late reply.

The 3504 is running: 8.10.185.0 - should i upgrade to 8.10.185.3?

Hmmm well that probably won't fix your air quality issue because 8.10.185.0 already has the fix for the CleanAir bug I referenced but you should plan an upgrade to 8.10.185.3 anyway because DFS is broken on 3802 in 8.10.185.0 so the APs are not currently legally compliant with the DFS regulations. You might get lucky and your air quality problem gets solved by the upgrade. It could also be a cosmetic issue.

Have you checked whether CleanAir is running on the radio on those APs?

Upgraded to 8.10.185.3, but the 9120 is still showing 0 in the Air Quality counter.

Cleanair is enabled on the 5ghz radio.

Then it's probably a cosmetic bug on the GUI.
