The products of the company AVM great source of joy. The new AVM Fritz! WLAN USB Stick 2 is really great. In Windows XP, the installation was very simple: Unpack, plug it in, automatic recognition by XP - done. Without any further action. Driver CD is not needed. Then just enter the network key, even I was able to connect via Wi-Fi. All in all, less than two minutes. Optional can be from the CD still install the software for the configuration, which is certainly useful, but not absolutely necessary.
My recommendation: Everyone wants to set up the WLAN, this product should look carefully and try. Support (if at all because required) is also recommended on the homepage of AVM.
