Mt300n-v2 iw error: nl80211 not found

I am trying to use the iw command on mt300n-v2 but got an error: nl80211 not found. My FW build 3.102 and iw was installed using opkg. My purpose is to use iw to add a monitor interface. Any help is deeply appreciated!

Sorry it uses MTK wifi driver and you cannot use iw opensource tools.

You can get a firmware from openwrt directly which comes with opensource wifi driver and you could be able to do that.
