Belkin Wireless G Gaming Adapter
May be this is an alternative, cause there is no driver issue, or am i wrong?
Any wireless Ethernet bridge device should work well. Examples include Belkin F5D7330 (please note that there are two variants, one with one and one with two antennas), D-Link DWL-G810 or DWL-G820, Linksys WET54G and Netgear WGE111. Also, Linksys has introduced an N model (WGA600N), which appears to be something similar. Normally, wireless Ethernet bridge devices do not require special drivers at all, and can thus be used under almost any operating system.
The various models (or versions of a model) may or may not support WPA security. A firmware update (which, typically, has to be carried out on a PC) may be sufficient. So, check the specifications (and the firmware download sites).
