Ok it is really a network bridge that allows you to hook equipment that has only an ethernet jack to your wireless network (Xbox 360, PS3, Printer, DVR). I am using it to hook up to a Xerox Multifunction device 4 floors away in my house. This thing is not easy to configure. I ended up going the way of changing my computer IP address to 1.1.1.2 and Gateway to 1.1.1.1 and then using the built in web browser to configure it. Took me about 20 minutes and then when I went to move it to its new location I was not even sure it was going to work. To my glee though, it did and even got a decent speed where my laptop did not. I think it is a great piece of equipment and if you are patient it does its job with great range.
