To address your immediate concerns you have nothing to worry about. The WMI hotkeys are not needed for WiFi to function.
Date of WMI updates
To address comments posted above; although your Dell-WMI compiled binaries haven’t been updated for 9 years, the source code was updated 2 years ago:
/* * Dell WMI hotkeys * * Copyright (C) 2008 Red Hat <firstname.lastname@example.org> * Copyright (C) 2014-2015 Pali Rohár <email@example.com>
The full source code can be found here.
Additionally it is compatible with kernel versions 2.6.30–2.6.39, 3.0–3.19, 4.0–4.12, 4.13-rc+HEAD according to this link.
What are Dell-WMI hot keys?
This picture shows the Dell WMI hotkeys in the top right hand corner of the picture. Three keys immediately above the keyboard:
How to tell if the driver is loaded?
Press each of the three keys in order and type in the terminal:
dmesg | tail
If the keys are undefined in Linux (as on my Dell 17R 7720 SE) you’ll see this:
[22029.994271] dell_wmi: Unknown key e0f0 pressed [22032.865727] dell_wmi: Unknown key e02a pressed [22033.153981] dell_wmi: Unknown key e02b pressed [22035.538910] atkbd serio0: Unknown key pressed (translated set 2, code 0x60 on isa0060/serio0).

If the keys were working a pop-up menu according to that keys function would appear on your screen. If they aren’t assigned, you can assign these keys as shortcuts to your everyday work functions. Personally I use a wireless backlit keyboard (Logitech K800) so never touch the laptop’s backlit keyboard and haven’t looked at these keys in years.
