There is no FCC ID printed on the router. The PIN is also not printed on the router. The exact model of the AP is DIGISOL DG-BG4100NU which uses RTL8186 and not the newer RTL8671. Firmware of the router can be downloaded here https://dl.dropboxusercontent.com/u/..._11OCT2014.zip Firmware of the chipset http://sourceforge.net/projects/rtl8186/
