    Advanced-N 6205 keeps dropping - Dell Latitude E6420

    shd

      Hi there - first poster here !

       

      I have a Dell Latitude E6420 with an Intel Centrino Advanced-N 6205 and periodically, the wireless keeps dropping and the eventvwr shows :

       

      "Authentication failed due to incorrect security password (key) (WPA/WPA2)"

       

      it also shows :

       

      "Security mismatch with 11n. 11n is not in operation"

       

      ....but then it sorts itself out !!!

       

      Router is fine as i have an IBM laptop that runs perfectly and has never dropped

       

      Software versions show (according the Proset Help/About) as :

       

      Intel ProSet/Wireless Wifi Software14.0.2.0

       

      SoftwareHOWFW0413D
      Driver14.0.2.2

       

      OS is running :

       

      Windows XP Pro version 2002 / SP3

      32 bit

       

       

      Has anyone else experienced the same and if so, can you advise me how to resolve please as its doing my head in and seems pretty flaky !

       

      Thanks in advance
