I have a Lifebook E751 with Win 7 Professional. My WiFi Adapter is a Centrino Advanced-N 6205 with the latest driver (220.127.116.11).
My router (AVM Fritz!Box 7270) has 802.11n enabled.
My E751, however, only connects at 54MBit/s.
When I check my Centrino´s properties, under the tab "Advanced", the property "802.11n Mode" is Enabled.
The available values for the property "Wireless Mode" are as follows:
Now where do I find the 802.11n Mode???
Any help would be much appreciated!
