I have setup hotspot and generally everything works fine.
Only question that I have is:
If a user disconnects from wifi, he needs to reenter username and password after a new connection.
Can I setup some time (and how) that would save users connection (credentials) and if he reconnects in that time he dont need to reenter them ?
Hope this is understanding 
How long are you looking to keep the user logged in after the disconnect? If you allow only one user logged in simultaneously, then that user will not be able to login from another device during that time.
I allow user to 3 parallel logins (laptop,mobile…) with one username. If he moves out of office he loses connection on mobile (4 example). I would like to enable that if he comes back in an hour he does not have to enter credentials again.
Is that posible?
thx
