I gave up on local campground WIFI signals several years ago.
I simply just don't depend of WIFI signals from all of the various sources. I carry my VERIZON MIFI unit with me everywhere we go. This works where ever VERIZON Cell phones work and will provide a great working WIFI signal for up to five of my devices..
My 3GB monthly data plan is private and secure and more than enough to provide us with checking in with the kids, paying a few on-line bills, and do some limited surfing of the internet... This small of of DATA however will not support any down-streaming of TV signals or videos... Most of those will use around 1GB per hour when using them...
We use our BATWING antenna to pickup the NATL BROADCAST Digital HDTV signals from the local towns for our HDTV fill each night...
Never have to worry about competing with the locals at camp grounds that have weak and loaded down WIFI signals trying to provide WIFI to their customers...
ALot of the users can use their modern cell phones to do the same thing and most often have access to a larger Data Plane. Our older cell phones are not setup for this procedures.
Most of the time I can use my Verizon MIFI unit going down the road with my computer using the internet... When mobile I have my Verizon MIFI sitting in a WILSON SLEEK Cradle that uses an outside antenna.. I have a similar setup in my OFF=ROAD POPUP trailer up behind the wrap around Valance Curtain sitting in a WILSON Cradle with an outside antenna. This gives us excellent HOT SPOT service all over the campground using our tablets.
