A:Answeractually it won't. you stated RV park and open wifi. the answer should not be answered with yes, but maybe, Less people better quality, more people the worse quality. The adapter will give you a better signal, yes, but your issue is not signal, its wifi saturation. As users get onto the wifi, especially in a RV park/Hotel or airport, the router pushing out bandwidth will distribute the bandwidth equally until all bandwidth is gone. So at some point you will not have enough bandwidth at your device, regardless of signal strength. You can even have your PC right next to the Wifi and you will get the same amount of bandwidth. Your best bet, if wifi is critical, is to have your own paid for Wifi dongle and use it when the local Wifi gets over saturated. hope this helps to explain.
A:AnswerYes it can. For best results, ASUS Repeater needs to be within range of a strong and stable router signal, and should be placed between the router and the location where you need better wireless coverage.
A:AnswerAs long as it's within Range of it's assigned source service router and WiFi source! I do not suggest exposing it to direct sunlight, rain, or snow, due to obvious reasons of damage caused by either condition!
A:AnswerIt should, if You are getting a good 2.4 GHz to 5 GHz signal from the provider. I would contact my provider first, for advise on whether or not using this device would be a benefit to you.
