Public WiFi in campgrounds can be anything from a cheap WiFi router/modem working at 56.6 mb to a "state of the art digital cable system" capable of multiple connections in the gigabyte range.

Most private campgrounds have a "barely adequate capacity with limited range" and you won't be able to get a good signal unless you're parked "next to the router" while in some of the more modern (or progressive)campgrounds, they may have multiple systems staged throughout the park and can provide the capacity to do almost anything you can do at home.

Most people don't rely on "campground WiFi" and have their own system, either a cell phone hot spot or an independent "mifi system". Ours is a Verizon Jet Pack. Cost is about the same as a cell phone plan but there are some discounts and some plans that are cheaper than others, so shop all of the options if you decide to get one. I know that AT&T has similar devices and plans, WalMart also has a "straight talk plan and device" so there are options available.

As for the campground systems, try to connect, see what you get, if you can do what you want, great, if you can't then power up your own system.
