Funkwerk's W-Client USB.11g promises a quick, easy, fast and secure connection to a WLAN for your laptop or any other mobile devices you may have lying around, all through a simple USB connection. Equipped with standard drivers for Windows 2000, XP and CE, Versions 4.2 and 5.0, you can further improve your wireless link by using an extension cable, allowing the device to work as an external antenna. It also uses PRSIM Nitro tech to triple the speed in WLAN networks with 802.11b and 802.11g clients and double in pure .11g networks. More drivers are available on request. Just $48.
