I have a Latitude E6440 that will not automatically connect to wifi using the default settings. I must open the Dell Unified Wireless Application and manually check the "enable wireless radio" box before the system connects. Once that is done the system automatically connects between wired connections and the wifi network like it should. If the laptop is rebooted or shut off and then restarted, the auto connect feature doesn't work and you have to manually set it again. Let me provide a little background for you....we normally blow away the "dell image" of Windows 7 Professional and apply our own Windows 7 Enterprise 64-bit. That is when the problem starts. I have been unable to get the E6440's to auto connect between our wired and wireless networks unless I perform the above mentioned steps. None of our E6420 laptop exhibit this behavior and auto connects properly. It seems that Dell has removed the "disconnect on wired connection" setting in the Wifi driver like it's set up on the E6420's and added that feature to a new "Dell Unified Wireless Application" instead. I tried taking the corporate Windows 7 Enterprise image out of mix by manually installing Windows 7 Pro 64-bit and then installing all the appropriate Dell drivers using the "How to download and Install drivers in the correct order" documentation. I get the same results. The system will not automatically connect and disconnect between wired and wireless networks until I manually set the enable wireless radio" check box. If I use the "dell image" from the recovery partition, the wireless network auto connects just fine. So that tells me that Dell is applying some configuration setting or registry entry that I'm not aware of. Any suggestions? Regards, Mike Berrey Grass Valley USA, LLC IT Desktop Support
