Extracted from the Guix Reference Manual:

§ 3.2 Hardware Considerations

GNU Guix focuses on respecting the user’s computing freedom. It builds
around the kernel Linux-libre, which means that only hardware for
which free software drivers and firmware exist is supported. Nowadays,
a wide range of off-the-shelf hardware is supported on
GNU/Linux-libre—from keyboards to graphics cards to scanners and
Ethernet controllers.  Unfortunately, there are still areas where
hardware vendors deny users control over their own computing, and such
hardware is not supported on Guix System.

   One of the main areas where free drivers or firmware are lacking is
WiFi devices. WiFi devices known to work include those using Atheros
chips (AR9271 and AR7010), which corresponds to the ath9k Linux-libre
driver, and those using Broadcom/AirForce chips (BCM43xx with
Wireless-Core Revision 5), which corresponds to the b43-open
Linux-libre driver. Free firmware exists for both and is available
out-of-the-box on Guix System, as part of %base-firmware (see Section
10.2 [operating-system Reference], page 193).

   The Free Software Foundation (https://www.fsf.org/) runs Respects
Your Freedom (https://www.fsf.org/ryf) (RYF), a certification
program for hardware products that respect your freedom and your
privacy and ensure that you have control over your device. We
encourage you to check the list of RYF-certified devices.

   Another useful resource is the H-Node (https://www.h-node.org/)
web site. It contains a catalog of hardware devices with information
about their support in GNU/Linux.

Cheers,
David.
