recently I've installed a Cisco WCS server.In the MAPS section I have added a map (outdoor area) and I have dragged the two access point in the map(1 RAP and one MAP) to see the heat map of the signal.The problem is that for the first 2 days it worked fine but now it give me the following error:
Error: Some of the AP's RF Prediction is not yet computed. Please go to the AP placement page and place the APs properly, specify the correct antenna and then recompute the RF prediction.
I tried to do all the suggested actions but I had no changes.
My WCS version is the 220.127.116.11 and it's working on a virtual machine (that I have restarted many times) with a trial license that expires in the next 15 days.
