Why 'iw dev' does not show wireless device?

Why 'iw dev' does not show wireless device?

[znavko]

Hello! I want to install the latest Guix 1.0.1 x86_84 on Acer Aspire 3 A315-42-R1JJ, AMD Ryzen 3 3200U/AMD Radeon Vega 6.
I've deleted from grub 'modprobe.blacklist=radeon' and added 'nomodeset' cause I have radeon and without 'nomodeset' option boot just freezes.

But I cannot see wifi. I've unblocked it with
# rfkill list
0: acer-wireless: Wireless LAN
 Soft blocked: yes
 Hard blocked: no
...
# rfkill unblock wifi
# rfkill list
0: acer-wireless: Wireless LAN
 Soft blocked: no
 Hard blocked: no
...

But iw does not see wireless device:
# iw dev
#

# ip link
1: lo:...
2: enp3s0
#

# lspci -vvnn > wifi
# nano wifi
...
Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter
...
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
Please, what to do? I cannot get the name of the network device.

All ath10k devices of which I'm aware require proprietary firmware 
blobs that Guix won't ship and Linux-Libre won't load.  Even 
though the kernel driver is loaded, I suspect you'll find some 
firmware-related errors in dmesg.

I'm sorry,

(Double). Yes, Tobias, I've dug this finally. This wifi card is not supported by LinuxLibre.

Please, would you give me advice, what to choose from mass-market ( in Russia dns-shop.ru )
for LinuxLibre and Guix in price under 540 euro ( 40.000 Roubles ) ???

I found this https://certification.ubuntu.com/desktop
But not sure it will exactly work with LinuxLibre. Also h-node lack some contemporary models.

You could try finding a device certified by the FSF's Respect Your
Freedom (RYF) program, see: https://www.fsf.org/resources/hw.

FWIW, I'm using one such device [0], and it works great.  Alternatively,
you could purchase a device using a supported chipset (the device linked
uses the Atheros AR9271 chipset); the hardware vendor shouldn't matter
much if the kernel has free drivers (and/or firmware) for the chip used
by it.

HTH,

Maxim
