    Centrino 6300 not using more than 1 antenna since driver update

    Layer8

      I have a Dell Latitude E6510 with the Intel Centrino Ultimate-N 6300 and a Netgear WNDR3700 acting as an access point.  I was using a clean install of Windows 7 64-bit with the drivers off the Dell Support site and was able to connect on the 2.4 Ghz and 5 Ghz network at 300 Mbps.  The problem was maintaining the 300 Mbps on the 5 Ghz connection, the link speed would jump around almost randomly regardless if the maching was idle or copying large files over the network.

       

      I installed the PROSet v13.2.1.5 package and now when I connect I see a notification that indicates it connects at 300 Mbps but it immediately drops down to 150 Mbps on 2.4 Ghz and 90 or 120 Mbps on 5 Ghz.  It seems to be 'disabling' an antenna regardless of how I am using the network.

       

      Firmware on the WNDR3700 is V1.0.4.68NA
