Wi- Fi enhancers -Yes I'm new to the RV scene

The important thing to remember here is to not confuse connection speed (often limited by outbound bandwidth from the RV park to the internet) with signal strength. A booster or repeater may help a weak signal if you are located at the back of an RV park and the wifi access point antenna is at the front by the office. It will not help if the bottleneck is the outbound internet connection from the rv park to the rest of the world, which if commonly the issue.
p.s. you should use a web site like fast.com to test connection speed, you should also note that the speed will tend to vary with network congestion
