[BPI-R3] No wifi

Banana Pi Router design BPI-R3/R3 Mini(MT7986)

Hi All!

I am new to RPI-R3 and trying to get it working. Have big problem with wifi - not working at all on any version. Error I get is:

[ 9.093786] mt798x-wmac 18000000.wifi: Direct firmware load for mediatek/mt7986_rom_patch_mt7975.bin failed with error -2

[ 9.104745] mt798x-wmac 18000000.wifi: Falling back to sysfs fallback for: mediatek/mt7986_rom_patch_mt7975.bin

[ 9.130350] mt798x-wmac: probe of 18000000.wifi failed with error -12

Tried with and without UART debug connected - no difference. Any idea how to fix it?

which image, have you wifi firmware installed?

Tried many including current one from the link below, SDCARD version.

Do you think OpenWRT itself is not enough and I need a separate wifi firmware? I couldn’t find such info in sources available.

Weird. The file should be there. What’s the output of ls /lib/firmware/mediatek/

5

No such directory.

root@OpenWrt:/# ls /lib/firmware/mediatek/

ls: /lib/firmware/mediatek/: No such file or directory

root@OpenWrt:/# ls /lib/firmware

Have you uart disconnected the full bootup? Which adapter do you have?

7

I have some CH340, tried to boot with it connected and without - no difference.

I have seen threads about it but behavior is a bit different.

Started original firmware from NAND and here I can see below errors, but wifi network is visible by default. Not sure why it’s AX6000 in the file name.
