This link from Ricardo272 led to a solution (Thank you!) Has anyone else come across this problem? More importantly, do they have a fix? We've run Dell Command Update and applied all the latest BIOS and Driver updates. The problem occurs both with our corporate image and a Dell factory image. We have already verified that the BIOS/Power Management/Wireless Radio Control has both options (Control WLAN / WWAN radio) selected, just like all previous models of Latitudes we've configured. Which, unfortunately, is the normal case when users first arrive in the morning. It's only on a full shutdown/power-on (cold-boot) that the problem occurs. And if the laptop is restarted (warm-boot), it properly comes up with only the LAN connection active.

If we disconnect and reconnect the LAN cable, the Wifi disconnects and only the LAN connection remains (as expected). When cold-booting the laptop in a docking station, or with a LAN cable connected, both the Wifi and LAN show up as 'connected'. We have started to deploy Dell Latitude E7270s in our shop and have noticed a problem.
