I have following topology: I am not a networking expert but somehow using the help of the Internet I was able to successful configure my topology so that I can access the Server remotely from any client connected to Wireless Access Point and also detect the Wireless Access Point in the controller software installed on the server. This server is Windows Server 2012.
But after installing Optical Fibre connection I am unable to do both the things together. Either I can connect to remote desktop or I can detect the access point in the AP Controller software. And sometimes the Internet stops working. I am unable to form a topology that can solve my problem.
