INTERNET and WiFi
NOTE:
WiFi is NOT the same as the Internet. If you have a hotspot (or use your phone as a hotspot) it will create a local WiFi network that all other devices can use to connect to like a TV, laptop, wireless printer or streaming media device. This does not mean you also have the internet connected. For internet, you need a cellular connection from the hotspot to a cellular tower. When there is no cellular connection you still have a working WiFi network and can print and stream from local sources.
You could also connect to the campground WiFi. The campground, in that case, they have a router and provide the internet connection thru that. However, most campground networks are overloaded because of users that are streaming or there is not enough bandwidth to provide everyone a workable connection.
