 • Support page

"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).

I've gathered some of GPIO functions:

Tested by telnet:

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.
