Unfortunately I have only 1 device with 4366B1 (D-Link DIR-885L) and
it seems to have dummy NVRAM restored from the bootloader's copy:
1:ccode=3DALL
0:regrev=3D0
0:ccode=3DALL
1:regrev=3D0

1) Old fw 10.10.69.3309 (r610991) FWID 01-c47a91a4
2 GHz: very weak signal (about -79 dBm)
5 GHz: good signal & works stable
(this also matches vendor firmware behavior)

2) New fw 10.28.2 (r769115) FWID 01-801fb449
2 GHz: very weak signal (about -79 dBm)
5 GHz: good signal but huge packet loss

So the new firmware introduces 5 GHz regression for me, but I guess I
should not complain since my device seems to come with a missing NVRAM
regulatory info.

Is there any chance you know a correct ccode + regrev for D-Link
DIR-885L for any region?
