suggestion 1 --->
you can load Unleashed software for R500 on your R500 AP which will give it controller based features and then you can use guest WLAN feature where you can allow users to just accept terms and move on to get access..
No webdesigning login page and setting radius server...etc
BUT it will NOT capture email address..
suggestion 2 --->
Again you can load Unleashed software for R500 on your R500 AP which will give
it controller based features and then you can use guest WLAN feature
where some one need to create guest passes manually and in that process capturing email + phone + name etc and then give it to guest.
No simple login page and radius server...
BUT someone got to create them manually either in SILO or batches..
hope this helps..
