Another problem for campgrounds is the "expert" that installs the systems. After 40 years in banking working with commercial accounts I've come to the conclusion that if any electronics person brags about being an "expert" tell him to go to that warm place and kick him out.
We were at a campground a few years ago and they had paid several thousand dollars to an "expert" to setting up their WIFI system but after several months it still didn’t work. They gave up on him, and found a couple of kids that said they could fix it but wouldn’t take any pay until it worked right and in just a few days it was working A-OK.
