Hi Vasa,

IIUC you are running a pretty old version of the driver. According to the rpi
kernel tree, mt76x0u enables radio frequencies up to 5700MHz

https://github.com/raspberrypi/linux/blob/rpi-4.19.y/drivers/net/wireless/mediatek/mt76/mt76x0/init.c#L565

I guess you need to update the driver to latest stable one.

Regards,
Lorenzo
