Additional Notes

This driver is Microsoft signed for WinXP, used with the Inventel UR054g Wireless USB adapter (and it should work with any other adapter based on the Conexant Prism chipset). Unpack the zipped folder to a location on your machine (desktop works fine) then plug in the adapter.

When Windows asks for a driver, give it the location of the folder you unzipped to. And then you are DONE! Once installed you may delete the folder you unzipped. :)
