I bought the Fritz! WLAN stick because I have shipped my PC in another room where there is no LAN connection !! right at the beginning there were problems because the driver of the on the stick and the CD was not available was 7 x64 bit compatible with WIN! But the problem I could by a driver from the manufacturer's website fix (after a few installation problems, I had to install the drivers manually from the Device Manager as the assistant had him installed incorrectly!) After that, I was only times well and without any problems surfing. After some time, however, caught the connection to constantly tear, which I can only recover by I put the stick out and in again or completely reboot the computer. I suspect that this is due to compatibility issues with our "T-Com Speedport 700V" wireless router and an immature x64 drivers because I now can no longer switch to Mircrosoft wireless mode. I have tried everything. Have encryption disabled, the router several times new gestarten and and and. On the Internet, I find, unfortunately, nothing. The stick will probably run on x86 systems without problems or with a Fritz! Box as a remote but I'm not satisfied with my situation with this product. Hope the new driver will fix the (PS: My connection may be disturbed by anything, the problems also occur regularly on)
