Hi all.
I bought a mini PC with x86 N5105 CPU which I tried to install WiFi card into.
I have read that MT7921 is supported by OpenWRT in x86 so I bought MT7921K.
This card has M.2 NGFF interface so I used M.2 NGFF to Mini PCI-E adapter.
Now everything is booting fine but I cannot see the card in OpenWRT.
I have installed "kmod-mt7921-common" and "kmod-mt7921-firmware" packages which I assume were needed but can not see any "radio0" device.
ls -l /sys/class/net returns this:

Does this mean that physical PCI device is not recognized? Is there anything more I can do before I tear into hardware?
Update. I downloaded pciutils package which allowed me to run "lspci".
Apparently, I do have WiFi card attached on PCI bus. But I am not able to initialize it.

I installed "kmod-mt7921e" and I can now see the card in iw list. To be continued.

Hmm, I got the card recognized but it seems that there are no MT7921K drivers available for OpenWRT.
The nearest I could come to is installing MT7921E driver. It would turn on radio but clients will not connect.
I will continue in hardware forum.
