The good news is that it appears to be supported in the upstream kernel. The bad new starts with this: $ grep -r MEDIATEK debian/config/ debian/config/config:CONFIG_WLAN_VENDOR_MEDIATEK=y debian/config/arm64/config.cloud-arm64:# CONFIG_ARCH_MEDIATEK is not set Which is not relevant for the Banana Pi BPI-R3 ... $ grep MEDIATEK /boot/config-6.1.0-11-arm64 # CONFIG_ARCH_MEDIATEK is not set # CONFIG_MEDIATEK_GE_PHY is not set CONFIG_WLAN_VENDOR_MEDIATEK=y ... "CONFIG_ARCH_MEDIATEK is not set" means that there (essentially) isn't *anything* wrt MEDIATEK enabled in the Debian kernel ... (same for 6.5 btw) I have a script which helps with identifying which kernel modules would be needed based on the "compatible" strings in the dts file and running it on the mt7986a-bananapi-bpi-r3.dts revealed 1 missing component ... but a rather important one, which AFAICT is related to ARCH_MEDIATEK not being enabled. The dts file also includes a .dtsi file and scanning that file revealed mostly missing "Debian config settings:" lines and thus also any enabled modules in the Debian kernel. My script is very crude and will only give a starting point which I then would enhance by filling in the missing parts. But I'm not motivated enough to do that for a board which I don't have (as it's quite a bit of work) ;-) Hope it still helps.
