My Turris Omnia was upgraded to the official Wi-Fi 6. Everything worked fine until I switched to HBD - TurrisOS 8.0.0.
The Wi-Fi 6 adapter is not recognized here:

# dmesg | grep -i mt79
[ 11.078356] mt7915e 0000:01:00.0: Direct firmware load for mediatek/mt7915_rom_patch.bin failed with error -2
[ 11.088324] mt7915e 0000:01:00.0: Falling back to sysfs fallback for: mediatek/mt7915_rom_patch.bin
[ 19.612215] mt7915e: probe of 0000:01:00.0 failed with error -12
So Iām looking for the right firmware. Maybe it is this one?
# opkg install kmod-mt7915-firmware
It seems to install the right file /lib/firmware/mediatek/mt7915_rom_patch.bin
And after the reboot it works fine
