Thanks George, I'll try again, this time with Vmware if I can
get it. I wasn't aware the kernel developers needed access to
the hardware for this wifi device as I thought, from what I've
read, that the kernel driver module was actually supplied by
Mediatek.
Mediatek devs usually provide drivers tested with a specific distro
and kernel. Changes are often needed for new kernels, and the device
has to enabled in the Fedora configuration, so lots of places for
bugs to go unnoticed until some user files a report.
One way to see where a driver works is the the
LHDB <https://linux-hardware.org>, but the site has become difficult
to use -- maybe due to a combination of new linux users and AI data
scrapers.
I've installed F43 in a QEMU/KVM VM and managed to get the 6.18
kernel installed and active, and also seem to have gotten the
akmods nvidia driver compiled as well, although the nvidia server
doesn't seem to be able to communicate. I can't check whether the
kernel has an MT7927 driver embedded in it because the VM can't
detect the wifi device so it doesn't offer me the opportunity to
try to connect via wifi.
There are some places to
look. /lib/modules/6.18.1-200.fc43.x86_64/config lists configured
modules. You
check /lib/modules/6.18.1-200.fc43.x86_64/kernel/drivers/net/wireless/mediatek,
for example:
% ls
/lib/modules/6.18.1-200.fc43.x86_64/kernel/drivers/net/wireless/mediatek
mt76 mt7601u
% ls
/lib/modules/6.18.1-200.fc43.x86_64/kernel/drivers/net/wireless/mediatek/mt76
mt7603 mt76-connac-lib.ko.xz mt76-sdio.ko.xz mt76x0
mt76x02-usb.ko.xz mt7915 mt7925 mt792x-usb.ko.xz
mt7615 mt76.ko.xz mt76-usb.ko.xz mt76x02-lib.ko.xz
mt76x2 mt7921 mt792x-lib.ko.xz mt7996
% ls
/lib/modules/6.18.1-200.fc43.x86_64/kernel/drivers/net/wireless/mediatek/mt76/mt7925
mt7925-common.ko.xz mt7925e.ko.xz mt7925u.ko.xz

Note that the author list includes both mediatek and kernel devs.
Sometimes one module supports multiple chipsets, so a future
mt7925e may support newer hardware. Once you identify modules that
match part of the chipset name you can check the "alias"
line for the PCIe vendor (here: 14C3) and device (here: 0717 and
7925) ID's.

Thanks George, I checked ls
/lib/modules/6.18.1-200.fc43.x86_6kernel/drivers/net/wireless/mediatek/mt76
and that has modules for mt7925 but not for mt7927. I does have
mt792x-lib.ko.xz and my792x-usb.ko.xz but a modinfo on those doesn't
list any firmware nor does it list any alias line either.
I also checked /lib/modules/6.18.2-00.fc43.x86_64/config for the
string "mt79" (case insensitive) and that is indicating it doesn't
have support for mt7927 unless the mt792x module provides it. But
before that I need to be able to get the VM to actually see the device.
regards,
I've now install the 6.18.3-200 kernel but that kernel doesn't supply
the mt7927 driver either, as I've seen on the net from someone else, but
this issue I have is that my wifi device is not actually using the
mt7927 chipset, it is actually using the mt6639 chipset and drivers for
that chipset don't appear to be in the kernel either, but I have seen
some info that said the drivers were expected to be in the kernel in
late 2025/early 2026.
