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 Software14.0.2.0SoftwareHOWFW0413DDriver14.0.2.2OS 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

Hello SHD, welcome to Intel Communities.
I'm sorry for the inconvenience that you have faced with your Laptop and the network adapter.
I would like to know if you are able to connected when security is disable, or without security?
There is a new driver version available, you may want to uninstall the current one and restart the system.
Finally install Intel® PROSet/Wireless Software version 15.8.0

Thanks for the reply Sylvia
I have not tried without security
As i say, i have 2 laptops....a Dell and an IBM
The IBM laptop works perfectly at home and at work using the wireless
The Dell also i do not recall having an issue at work running wireless but at home, some days it works ok, but other it will drop, reconnect, drop, reconnect, and then sometimes require a reboot just to let it start working again
Other devices (wifes andriod and our google nexus have never had an issue)
I have just checked the link you supplied but noticed there is a driver only and complete software option also :
Drivers only: Wireless_15.8.0_Dx32.exe
Intel PROSet/Wireless WiFi Software (includes Drivers): Wireless_15.8.0_x32.exe
Can you advise is it driver only or the complete software bundle and can you give a few instructions please of the steps to go through ?
Thanks again for the reply Sylvia
