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.

Without the diversion, zutils would violate the rule that the same file can't be installed from more than one package. It's exceptional enough for you to be warned that it's happening, but particularly because the default behaviour will be changing at some point. Anyway, it's expected behaviour. Cheers, David.

Re: where to find wifi card info in linux-doc
Thank David! i want info about wifi adapters supported by kernel without using non-free firmware. i haven't been able to find such info in linux-doc yes, search for such info isn't easy, i give up many web pages have stories of linux users' success with wifi adapter but they might use non-free firmware BTW both opensuse and fedora include non-free firmware in their official images they r so serious about open source that they don't include mp3 player (you have to use 3rd party repositories) i think debian shall re-consider its policy on non-free firmware

Your original question was about wifi cards, then corrected to adapters. Generally, the kernel docs deal with chipsets, and are fairly uninterested in which hardware they are embedded. This can be frustrating when you want to purchase a suitable device, as even the same model name (on the box) can have different chipsets inside from one instance to another, particularly with cheap ones. So it might help to clarify from which viewpoint you seek the info, and any particular cards/adapters/chipsets involved. Cheers, David.

This actually works recursively with the zgrep command from the zutils package, thank you! The installation of it throws interesting warnings on testing...

It is always better to use the original source cd linux-4.19.190/Documentation grep -r -i wireless . sorry for not mentioning that and I wonder how it is possible that the Documentation directory has different content and notice -i wireless (means ignore case for wireless) , while -r is to do recursive grep -- FCD6 3719 0FFB F1BF 38EA 4727 5348 5F1F DCFE BCB0

sorry, i use wrong word i mean wifi adapter, not wifi card in Chinese, it's called wireless card, though it's really USB wifi adapter
