WCS RF Calibration - Client not detected

[td3tsu]

I'm using WCS 3.2.51.0 controlling a WiSM with the controllers at 4.0.155.5.

I'm trying to use the mapping features and create a RF calibration model. However when I go to add data points then enter the wireless MAC of an associated client and then pick the building and floor from the list I receive the message:

"<MAC> is not detected as a Client on the Chosen Floor. But it seems to be on Floor :"

However I can go to Monitor => Devices => Clients => Floor Area and then select the same floor and I'll see the MAC address listed on an AP that is assigned to the floor I'm trying to calibrate.

Any ideas?

This issue is called the MAC spoofing. This can be removed by creating the DNS hopping technique. This Probelm arise due to soem Rogue APs near the access points.
