I have a problem with the prepaid card on user manager..
user with 1 hour credit… works half of his time.. he logged out! the counter keeps counting… knowing that the counter is cumulative! and the user should still have the other half to expire…
Is your customer actually logging out of the hotspot (http://hotspotname/logout) ??
If not then they will never be disconnected unless you have an inactivity timeout set. This means that if the router can’t see the user for x amount of time the connection is terminated and the counters stop. If the user actually logs out properly using the command above there should be no problem.
If you are using any customised login scripts or frontend you may not still have this option, so make sure you set the inactivity timeout, very important.
