Use of VPN in public setting
I often take my laptop to a public wi-fi for use, and I connect through my VPN.  However, I often get kicked off or disconnected, making it difficult to accomplish any real work.  I do not have this issue when I connect with my home wi-fi.  Is there a different standard of connection with public wi-fi versus the wi-fi I use at home?  Do I need to utilize another system to connect?  Thank you.
