Please notice that the application (since it is not a driver after all) are only required to configure the device and set the SSID specs.
So I got this VAP11G at ebay for $17 to try it out. This can be usefull for devices like TVs, Xbox, Ethernet only printers, old ethernet computers, or even for OS/2-eComStation when you don't have a wifi adapter driver for it. So, if you have a device that do not have Wifi and only have Ethernet, you can use one of this to connect this device to a Wifi access point. This is a wifi network interface that connects to the Ethernetport. I always wanted to try one of this adapters.
