While going great with Windows 7, but with 8.1 it crashes the computer when installing the Linksystreibers from. The Fix it is, the stick seems to work only with the supplied software, ie plug and start the search with Windows for driver works not because the stick is not even recognized! Second gripe: A stick with dimensions half Zigarettenschachttel is in a computer USB port lifted very bad because part an external stand forth like the ASUS AC 56 Thirdly, the support is quite miserable, anyway, I rummage there on the website still found after 10 minutes around no way to submit a request via email. As an alternative, I then brought my ASUS SC-56 WLAN stick.
