This is how to set up a Nanostation. However, here is my experience of using this across Europe and helping other people I have come across struggling with their sometimes expensive solutions.
The main use for a boost system is on campsites or Fon. I have connected to open access points but usually found these to be dog slow. I do connect the nano to a router. This allows multiple connections to the SSID without paying for each connection. You can get a router from about £15. I use a ubiquiti one, cost £30.
I also have an unlocked huawei Mifi unit. This can also be configured to access to a wireless lan as well as 3/4g. I use this when I can get cheap data deals in countries. However the Wlan aerial I have is useless try a ws320 booster aerial. but is OK for multiple connections on a campsite and needs no power, plugs into a USB. Your last solution is to sit in a cafe. For £2 you can download a heap of stuff. So my advice is look at your needs of when and where you want to access the net and chose the best fit. I certainly would not spend a heap of dosh buying a motorhome specific one as they are rebadged ubiquiti kit that you can buy for half the price on the web. Do not under any circumstances buy anything with an omni directional aerial. A Mifi device could be the best solution, and with roaming charges disappearing will offer a better roadmap to the future. 4G will give far better performance than wifi also going forward. But buy an unlocked one from Huawei or ZTE. do not buy a NetGear one and make sure it has Wifi Lan access built in. Or sit in a cafe when you need it.
These are the settings to set up an Ubiquiti Wifi boosting station. You only have to do this once. After initial set-up all you need to do is select the SSID by selecting the best network available from the SELECT button on the Wireless Tab.
