I have a 526 controller and 4 521 APs on my LAN that I want to upgrade to LWAPP. I am using CCA and all the help says this should be a point-and-click type of thing. However, when I try the upgrade the CCA asks for an image I don't have and can't find in the CCA folder. The download section for the 521 doesn't have it either. Where can I get this image? Is there another way to upgrade?
Thanks in advance,
