I assume you mean TL-WN8200ND? That device is 'interesting' in the least positive sense of the word. It seems abandoned by the manufacturer too. I have one of them but never managed to get it working, not with any driver under Linux nor Windows. TP-Link shipped a driver disc with it, but you cannot install that in any recent version of Windows because the OS ships with it's own driver for the 8192cu/8188cu series and the device uses the common USB ID. I have been meaning to see if I could find a box with Vista on it to install their driver and run a USB trace on it. > One other problem that I have found is that the debug option on module > load seems to be ignored.
