I have wireless APs broadcasting a SSID campus-wide that is using WEB-Auth. I connect to it, open a browser and get taken to a splash screen asking for credentials. I sign in and can get out to the Internet. When I walk around campus and associate to another AP, it forces me to login again. How do I stop this from happening. I don't believe the problem is on the client has it happens on multiple clients/platforms. Using Cisco APs and WLC.
