@hyf Thanks for your reply. For the MediaTek MT7925, I did install the kernel all modules called kmod-mt7925* and their dependencies from here. I checked multiple times and to my knowledge I don’t think I forgot anything.
In case anyone is interested, I will post some logs from the boot with a MediaTek MT7925. The reason for posting them here instead of opening a new topic is because I’m genuinely curious to find out why some Wi-Fi cards don’t work, or whether they have different root causes. I am ready to perform further tests if anyone has any ideas.
The output of dmesg does not show any error, but just “Phy link never came up” (both for the Mini PCIe that has the MediaTek MT7925, and for the empty M.2 slot). We can also see that the mt7925u driver is being loaded:

The output of lspci does not show the MediaTek MT7925 (note: the error below is unrelated, and not displayed when executing only lspci without further parameters):
root@OpenWrt:~# lspci -nnk

The output of lsusb shows that the MediaTek MT7925 is detected, so Bluetooth would work (but that’s not what I need):
root@OpenWrt:~# lsusb

The following two commands have no output:
root@OpenWrt:~# wifi config
root@OpenWrt:~# iw dev
root@OpenWrt:~#
EDIT: I forgot to mention that before buying any Wi-Fi card, I checked out whether it is fully supported by the Linux kernel (and by which kernel version) according to the documentation. Specifically for both MediaTek cards mentioned above, according to the documentation of this driver.
