New Dell Latitude 5420 Wi-Fi problem.

Recently at work we deployed around 20 or so brand new Dell Latitude 5420 laptops to two departments. Both were set up in house, one group received Dell-WD19S docking station the other did not. For the past week or so we have been having an issue where a few people for the dock group have brought their laptop's home only to find out that they are unable to turn the Wi-Fi on on the computer. They have tried to turn it on manually through the settings menu but the switch snaps right back to off. Restarting has no effect. So far we have changed the setting in device manager to not allow the computer to turn off the wireless card off, we've changed Bios settings, and found and installed the latest drivers from intel, nothing has worked. We have also updated the drivers for the docks. The dockless group has had no Wi-Fi issues at all. The IT department is stumped. Any input would be appreciated.

TLDR; Got new Dell laptops and docking stations. For some reason the Wireless card turns off and will not turn back on even after restarting.
