Internet through WiFi is a two way street. You need the power to send your request to the access point, and the power to recieve the signal coming back. The internal adaptor in our devices usually has about .02 watts of sending power and about 1Db gain on the antenna recieving the signal coming back. The Alfa is great because it adds the power on both sides. The Alfa has a full 2 watts of sending power, and about 8Db gain on the recieve side. The RV park is responsible for the bandwidth and there is nothing you can do about that side of the equation. Our internal adaptors are not designed to capture a signal from long distances like in a RV park, add the Alfa booster and you can now connect to that signal with ease. They work!
