How are Wireless devices remembered when they try to reconnect to a wireless Network?

I am trying to setup a new enterprise Wireless system and our Corporate Wireless Network uses Widows RADIUS Servers (Network Policy Server).  When the corporate devices connect to our Employee Network  the employee's username/password credentials are remembered the next time they login.

I have also setup a Guest WLan for employees to logon with their personal devices (BYOD) and that WLan uses WIndows RADIUS servers taht are registered to our Active Directory Domain.  The BYOD WLan is actually using the same Windows RADIUS servers as the Employee network is using and authenticatin is working for the BYOD captive portal.

The problem I am running into is that e mobile devices are not able to reconnect to the BYOD WLAN without entering a username/password every time.  Unless they are windows devices (Surface Pro. tablets)  that are not part members of the active directory domain by the way.  So our Android, Apple, linux laptops and phones need to sign in every time because their devices are not remembered.  

The current production system (HP) using different Windows RADIUS servers does remember all mobile devices the next time they try to connect; but, the new system does not.  I am wondering if I need to set a specific configuration on the Network Policy Servers to remember non-windows devices?  It should be possible because the older system can do this.  But the new Wireless Vendor has informed me that to do this I need to allow MAC address caching and that is only allowed if we purchase another appliance.

I am curious about that response.  My questions are:

1.  How do Wireless Systems remember devices when the logon from a web page/captive portal, when using RADIUS servers

2.  Do I need to configure something to enable Windows RADIUS Servers to remember non-windows devices when trying to re-connect to the SSID?

3.  What is funny is that the Windows device reconnect or are remembered easily with this specific captive portal, as long as their MAC address is still in the user table (as long as the session idle time out has not expired).

so how can I enable non-windows device to get remembered?
