Have to agree with others in that the WiFi at most campgrounds simply won't support any type of streaming video. They typically barely support enough data flow for browsing and email. I am fairly fluent and experienced with WiFi (not an expert by any means) and gave looked at many options but they all come down to the total bandwidth that the campground connection offers. A lot of campgrounds, in fact, block access to streaming services for just that reason.
