Public Access "Hotspot"

I have a couple of 133/R52s used as open public access points in businesses, one in a showroom and one in a cafe.

Is there a way to display a web page for 5 seconds or so (an ad) upon a customer connecting before going to their home page without configuring Hotspot?

Or, if Hotspot needs to be configured and directs them to the customized internal login page, can they be logged in automatically without supplying any username or password, maybe just clicking on a login box? Could you use the “trial” method of logon for this?

Any help would be appreciated.

Having the same issue i was able to configure the page but it displays and disappears very quickly.

This login page is a good place to present an AUP, and rename the login button accept.

This would require hotspot.
