I have been trying to design a project on my R-pi for months. I have been able to work of my R-pi from my home WiFi. However when I enter my Library's public network it cannot connect to the servers. This is why I want to connect my R-pi to my laptop over an Ethernet connection so it can use the Library's WiFi connection. I'm not sure if this is even possible as I am new to R-pi some any comments will be greatful.
UPDATE with info from comment:
My Laptop and R-pi have been connected over my WiFi connection allowing me to transfer PLC programs designed on my laptop to my R-pi. However when I move away from my home WiFi I have to change the WiFi on my R-pi all the time. So I am just wondering can I connect my R-pi to my laptop over an Ethernet cable.. No the laptop isn't able to see the server as it is on the R-pi and the laptop has no communication to it. Hence I want the Laptop to be able to communicate with the R-pi when the Laptop is connected to a public WiFi source.
