"P/N: 141911720003J R01C" is silkscreened on the board.

The default SSID patterns for this model is:

belkin.XXX (where XXX is the last three octets of the wireless interface MAC for this SSID) and
belkin.XXX.5GHz (MAC = 2.4GHz network MAC + 2, same XXX from the 2.4GHz network).

The guest network is (if enabled) belkin.XXX.guests

(MAC = 2.4GHz network MAC + 1, same XXX from the 2.4GHz network).

GPIO[edit]

I've gathered some of GPIO functions:

Tested by telnet:

GPIO
gpio disable 5 #internet blue on
gpio enable 6 #internet orange off
gpio disable 6 #internet orange on
gpio enable 5 #internet blue off
gpio disable 8 #modem orange on
gpio enable 8 #modem orange off
gpio disable 11 #modem blue on
gpio enable 11 #modem blue off
gpio disable 9 #router blue on
gpio enable 9 #router blue off

#Long press resset button
gpio pool 10
pressed = 00
unpressed = 01
gpio disable 10 #factory reset

gpio enable 12 #security orange off
gpio disable 12 #security orange on
gpio enable 13 #security blue off
gpio disable 13 #security blue on
gpio enable 22 #storage orange off
gpio disable 22 #storage orange on
gpio enable 23 #storage blue off
gpio disable 23 #storage blue on

#wps button
gpio pool 0
pressed = 00
unpressed = 01

Gathered from OpenWrt:

  • wired/wireless leds are controlled via bit shift register sitting on gpio pins 14 (ctl) and 4 (clk)
  • speed leds are controlled via bit shift register sitting on pins 17 (ctl) and 18 (clk)

Some notes:

  • restore config function doesn't work properly, the router get stucked.
  • PPPoE doesn't work with preselected want port, bridge port must be selected for wan, br0
  • current firmware level is more to instable to use it for a long period of time,
if there will be any new releases and if the time permits I'll test them.
