I bought the EDIMAX to get on the internet with a RPi via WLAN. If you follow the various instructions in the nets has also determines success with this stick (three others who were with me around here it does not work). The Stcik can also be used to operate the RPi as Accespoint or router. A star deduction, because the coverage of the house is really modest. Specifically: in a "critical" point in the House have any other devices (laptops, netbooks, mobile phones, tablets ...) yet sufficiently receiving the transmission rate drops when halfway aktzeptabler data rate, the EDIMAX can still connect there with the router, but to intolerable values .... A pity, but was also due to expected design (I really wonder how an "antenna" is integrated into the device ...).
