I have configured a Cisco 2100 WLC. I have configured two WLANs, one of them with Web-Authentication. When I connect to it, I get an IP address, and if I open the browser, I was redirected to the authentication page (in the browser toolbar appears "http://126.96.36.199/login.html", I understand that it works correctly), but doesn't load the page, as if not found (I.E. doesn't find).
I searched the Cisco configuration examples, and in this forum, but haven't found any similar problem.
I got it try this
go to virtual interface wich u created 188.8.131.52 in wlc in controller>interfaces>virtual
remove the dns name if any, inside the virtual interface
it will work
