And I Plugged usb wifi dongle to OpenWRT x86 server
Lastly, I checked kernel modules

root@OpenWrt:~# cat /proc/modules  | grep mt7921
mt7921u 20480 0 - Live 0xffffffffa0476000
mt7921_common 57344 1 mt7921u, Live 0xffffffffa0462000

I don't know what the problem is.
Please give me some advice

frollic · August 16, 2023, 12:59pm

it's isn't ?

what's the 3574:6211 Mediatek Inc. Wireless_Device then ?

kernel version might also be an issue.

kkyoon · August 16, 2023, 1:10pm

The kernel version is as follows

frollic · August 16, 2023, 1:11pm

then you know what the initial problem is ...

kkyoon · August 16, 2023, 1:15pm

Where is webpage that has kernel version information for OpenWRT?

frollic · August 16, 2023, 1:16pm

googled "openwrt kernel" ?

kkyoon · August 16, 2023, 1:21pm

Thank you for your advice.
It still doesn't support the 5.18+ version kernel on OpenWRT x86, so mt7921u doesn't seem to be supported.

23.05~ and master have kernel v6.1 based wireless drivers (backports) and the mt76 driver versions are even newer than that.

I changed OpenWRT version from 22.xx to master
Still undetected

Something's wrong. Even the 802.11n dongle is not detected.
