Wikidevi Notes[edit]

"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).

Notes[edit]

GPIO[edit]

Source

I've gathered some of GPIO functions:

Tested by telnet:
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.
