Cudy WR3000 V1 is an MT7981B (AKA Filogic 820) based wireless router. It
has 256 MiB of RAM, some LEDs & buttons and (not described yet) 4
Ethernet ports.
There is one slightly uncommon LED with a label of globe icon described
in the Quick Installation Guide as having 2 meanings:
1. "Not connected to the Internet"
2. "Connected to the Internet"
Vendor designed it to light up when some Internet-accessible IP can be
reached. This change will be follow by an attempt to define some
predefined FUNCTION for it.
