Hi Philippe, Could you try the latest firmware to see if it can help with the issue you reported here ? Please check out https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek and replace the following three files in /lib/firmware/mediatek on your target and reboot 1) BT_RAM_CODE_MT7961_1_2_hdr.bin 2) WIFI_MT7961_patch_mcu_1_2_hdr.bin 3) WIFI_RAM_CODE_MT7961_1.bin Sean > >Thanks, >Philippe > >> >> >> Regards, >> Deren >> > > >
