Is there a way to use a Raspberry Pi to take a (public) WiFi Signal and create a hotspot such that devices can connect wirelessly to the internet via the Pi?
Moreover, can this be done if a network has no password set but requires a user to login with credentials?
The use of this would be to create an access point for multiple devices if a login to a network would have to be acquired separately.
Setting up an Access point as WiFi router/repeater is not a problem.
The problem is the user to login with credentials. I suppose this is done with the internet browser on a login page. You can script this login but there is no standard login procedure. Every site has its own procedure so you have to script every login separately. And it is not a simple task to script it. You have to analyze the html GETs and PUTs and send the expected pages with login data. Or you use a "browser emulator" that can handle dialogs automatically in a human way.
