i ordered a TP-Link TL-WR902AC and there is a new revision v4. i flashed the v3 firmware on the off chance. This worked right away. however, he has not recognized the 5g wireless. after some research I came across it is a MediaTek MT7613BE 802.11acn. I searched for the necessary kmod packages and came across kmod-mt7615e kmod-mt7663-firmware-ap. So everything works fine. maybe there is a maintainer who can build this automatically.
