[SOLVED] How do I disable my Wi-Fi and Bluetooth Adapters?

OS: Arch Linux x86_64 
Host: Inspiron 5559 
Kernel: 5.3.8-arch1-1 
Shell: bash 5.0.11 
DE: Plasma 
WM: KWin 
Terminal: konsole

Is there a method to disable my Wi-Fi and Bluetooth adapters via the terminal or GUI?

I searched the web for, "How do I disable my wifi adapter in Arch Linux?" and procured no relevant results.

Additionally, I searched the web for, "How do I disable my bluetooth adapter in Arch Linux?" and got a few links to the Arch Forum, but the solutions are not
completely relevant to my query.

I would like to learn a method to not only disable the service, but to completely disengage the hardware (Wi-Fi and Bluetooth adapters) from the OS.

Find out what modules are used by your Wi-Fi and Bluetooth, by for example, command: 'lspci -k' and blacklist it: https://wiki.archlinux.org/index.php/ke … acklisting

In all seriousness, what is the goal?  Security? Power?

While soldering was intended as a joke, if the concern is security related, then unplugging the relevant hardware would be an option to consider (no soldering needed, but opening the case often is).  Anything you do from software could be undone via software.

Certainly there are things that may need root access to be done and then (barring other significant security issues) would also need root access to undo: unloading the modules would be an example of this.  However, if these solutions are sufficient for your needs, and the issue is security, then there may be better options such as only allowing root to access these bits of hardware (which is the "default" state anyhow).

In other words, if the concern is that any process with root access could access these devices, then unloading modules will not help as those same processes could simply reload the modules.

What about using the sysctl kernel.modules_disabled=1 to stop module loading? [1]
Which I believe can not be reversed without a reboot.

Hahaha :] I wouldn't mind removing the hardware, but I may have a need for Wi-Fi and Bluetooth with my secondary OS.


I am concerned about security.

The primary reason for this concern is actually health related. If you are curious, research the topic of RF radiation as well as EMF radiation and the affects on the human body. Just a fair warning: there is a lot of disinformation regarding these topics on the web.

This is gonna be fun…
