Gary,
WeBoost are great, but they are only for cellphone signals.
If you are trying to do better with campground WiFi, the first thing to do is to look at the signal strength display on your device. If it is more than one bar, the booster will only serve to frustrate you. If there is signal, but no bandwidth (speed) then the system is overloaded. Most are most of the time.
If signal strength is a problem and you are not a homesteader, then look up Alfa 036(XXX) units on Ebay. They are inexpensive and very portable.
If you really need wire (internet), then you really should investigate cell service.
Do I need to say BTDT???
