WlanKarte: Intel Corporation Ultimate N WiFi Link 5300
Router: FritzBox 7390
Wie beschrieben nutze ich die obige WlanKarte (MiniPciExpress) in einem Laptop. Der Router unterstützt Verbindungen bis 300Mbit/s. Allerdings komme ich nie über ~130 hinaus und die Geschwindigkeit schwankt zwischen 6 und 54Mbit. Direkt vor dem Router erreiche ich auch maximal 130.
Woran kann das liegen?
Hier noch die Infos!
