Re: Latitude E6400, Intel Wifi Link 5300 AGN Drops Connections

FWIW, the Intel 5300 in my M4400 (same card as yours) supports WPA2.

I'm using WPA2 to connect to a "g" 2-wire 2701 router, and though I prefer TKIP (less intrusive polling) it connects fine with AES as well.

Default settings of Power Management - Highest, Roaming Aggressiveness - Medium, and Power Saving Mode - Off.

Latest Dell driver ( but I uninstalled the included PROSet software.

You might try installing the Vista SP1 Wireless Feature Pack from the Dell downloads page for your system + OS; it seemed to help the stability of my WiFi as well as my BlueTooth connections.

I'm running a fresh install of Vista Business x64.
