I have 8 AP's right now, plan to add several more over the next few months.
I double-checked to make sure I was connected to the controller. I did not have the controller ip address in the browser, but I never had before. I always have used the first IP address on the 1st AP I installed and it has always worked fine. However, when you asked me if I put in the address of the controller, I checked that IP and pulled it up and it appears to be working ok now. Yet, if I put in an IP address of a AP, it still does the same thing. Weird
