Troubleshooting with CleanAir
The real power of CleanAir is that a network administrator can be on one continent
while the Wi-Fi spectrum in another office on the other side of the planet can be
analyzed directly. The 3500 access points can be put in SE-Connect mode and
used as a virtual remote interface for the knowledgeable engineer, no matter
where this valuable human resource is located. By changing the role of your
CleanAir access point and connecting the Spectrum Expert 4.0 software, the
Wi-Fi network administrator can now view the environment directly. There is no
longer a need to fly expensive personnel onsite to troubleshoot physical layer
issues that are unknown and challenging and, too often, intermittent issues.

Accessing Remote CleanAir for Spectrum Connect
When the call for assistance arrives, it is almost certainly to be in a location that
does not have the knowledgeable human resources to troubleshoot, identify,
and fix the issue. Wi-Fi radios are designed to send and receive Wi-Fi signals,
but they do not have the capability to identify non-Wi-Fi radio interferers such as
microwave ovens, DECT phones, analog wireless cameras, or even radio jammers.
The specialized radios in the CleanAir radio can identify and, with triangulation,
can locate where these devices are located.

When the call comes in, it is always important to identify as many facts about
the issue to make informed decisions. The information can be the location of the
problem (for example, “the street side of the building does not have connectivity”)
and time of day (for example, “the issue is pronounced at lunch time”). With as
much information as possible from the end user, look at the radio environment
because the system shows that clients are connecting and Cisco WCS indicates
AirQuality has dropped…

Configure Spectrum Connect
The CleanAir-capable access point must be changed from either Monitor Mode
or Local Mode of operation to Spectrum Connect Mode.

Step 1:
Log into the Wireless LAN Controller
Step 2:
Navigate to WIRELESS.
Step 3:
Select the CleanAir access point that is closest to the suspected issue.
Step 4:
From the drop-down menu next to AP Mode, change to SE-Connect.
Step 5:
Click Apply and wait for the access point to reboot and reconnect to the
Wireless LAN Controller.
