Hotspot + freeradius

Hi
I need some help. I have a hotspot controller based on RouterOS 5.20, and remote radius server for hotspot authentication. For now I am able to log to hotspot using a webpage. My goal is to do something like this: when one computer is logged in once, then any time this computer goes into hotspot area it will automatically connect to my hotspot without logging in. Can I use certificates and WPA2-Enterprise to achieve this goal? Or maybe you have any other ideas. Thanks in advance for any help.

Just enable cookie in the hotspot server profile and set the cookie lifetime to whatever time you desire.
