Nothing of the sort. Without Windows Installer CD (because Linux system) functioned both routers immediately. In addition, this model is much quicker than my old. Also very good: The WLAN can be switched off by pushing a button. The reception quality is good. Have I gained this model for wireless Internet connection in the garden. I am very pleased. At a repeater I can do without, fortunately.
Can recommend any beginner and advanced, this affordable device. The price-performance ratio was unique.
