I noticed a lot of you you have your preferences on wifi extenders. Please don't kill me here. Be careful on what you are referring as an extender. There are repeaters, there are clients and there are extenders. This device referred takes a 2.4 ghz signal and then rebroadcasts it with a modified SSID. You can resecure with different encriptions or make it an open hot spot. I am referring this device as it is the simplist and also is not intrusive in an RV Park. Also it will clone the MAC address so multiple device can attach as a lot of RV parks use Tango Internet and tie the MAC address of a devices and only allows 1 device to connect unless the RV park give you multple passes to their wireless infrastructure. Just my 2 cents, we all have our preferences on how to implement technology.
