We have a 2106 that was configured by a former employee. No one left in the company is qualified to configure it. The wireless guest access used to work fine. We'd configure a guest user account. They would connect to the guest wireless, open a web browser and login. For some reason now there is no prompt for login. People can connect to it and get an IP address, but that's it. No login prompt or anything else from there.
User Login Policies was set to 0 and I put it to 8. That didn't do anything. Under Web Auth > Web Login Page it's set to Internal (Default). I don't know where else to check. Anyone have any ideas?

Check to see if the certificate is expired. If when it was working, you didn't get a certificate error prior to the splash page, then there was a certificate installed. If so, you will have to get a new certificate.

On the CLI of the WLC you can issue a show certificate summary and that will tell you if you have a 3rd party certificate. On the GUI you can go to Security tab, WebAuth, then certificate to see the certificate used if any.

Yep, that was it! Thanks!
We did redo our network infrastructer about 6 months ago, and we changed the DNS settings in the WLC except for guest access.
