I have acquired one of these and am trying to to install OpenWrt so I can use it in Client mode.
The hardware is 4 x 100Mb Eth ports, 1 ADSL, 2 Buttons, 1 Power and a Secure Easy Setup Button.
CPU is a BCM96348 with BCM4318 Wifi and a BCM2535 switch. 1 x 4Mbx8 Flash and 2 x 8Mb Ram chips.
I've seen similar setups listed in the hardware database, so It should be useable, and I can telnet to the unit and access the Linux system there, but I can't get the router to accept any OpenWrt firmware.
I have found a webpage that lists the jumpers, and my next attempt will be to connect a serial console, and see if I can update via CFE, unless anyone can suggest anything else.
Thanks
Darren
