Wireless is disabled when Ethernet is connected

Hi peter_sgc,

Thanks for the post! The Latitude E5440 systems can be configured to enable/disable connection to through a wireless network if configured in the systems BIOS.  

The setting can be found by entering your systems BIOS (Restarting the system and pressing When the Dell logo appears on screen)

Navigating to Power Management >> Wireless Radio Control

Here you can enable / disable the feature to sense the systems connection to a wired network and subsequently disable the selected wireless radios (WLAN and/or WWAN)

Thanks,

Hello Shawn,

I disabled this bios feature (Latitude E7440) but still the wireless LAN is disabled when LAN is connected

Exists a DELL power app or Wireless control App for this? (windows 7)

Thank you very much

Wireless Adapter: Intel(R) Dual Band Wireless-AC 7260

I have a E5430 this is what we use for work i would connect the lan go to the Windows 7 "Control Panel --> All Control Panel Items --> Network and Sharing Center --> Change adapter settings --> look for the wifi thats disabled or disconnected --> right click diagnose --> then click fix --> this forces the laptop to enable it even though your wifi hardware switch is on --> it's a known dell issues this is the only workaround i found that works it's a hassle but it works

Hello Peter. I had the same problem. There is a service in the Windows called "Wired AutoConfig" that you need to disable to the Wi-Fi adapter do not be automatic disabled. Do it, and enable the Wi-Fi adapter, he wont be automatic desabled again.
