This is a Dell Latitude E6430. There is a setting in the bios to control this behavior and I have DISABLED it but it still happens. I am also running the latest bios.
When I plug in a network cable the wifi adapter becomes disabled. I need it to stay enabled. What else could be making this happen?
EDIT: The reason I need to do this is because with NETSH WLAN commands you can create a wifi hotspot by sharing the internet connection on the wired adapter and broadcasting a ssid on the virtual wifi nic. I do this all the time but it's not working on this laptop. I'm wondering if it's a network security thing where I am. I'm going to try from my hotel tonight and report back.

In my case the problem was a Windows service called "Wireless_AutoSwitch." I have no idea how or why it was installed but disabling it fixed the problem.
