Case is held together with 4 screws under the rubber feet.
Inside, note grey side wall is attached to the aerial
There is a 3.3v serial header near the front, behind the LED's marked J503
Pinout:
[x] (x) (x) (x) Gnd TxD 3.3V RxD
Reflashing
Attach a serial cable and an ethernet cable to the router, connect both to a PC/Linux box with a tftp server in.
Download the generic flash image: http://downloads.openwrt.org/backfire/10.03.1/brcm63xx/openwrt-96348GW-generic-squashfs-cfe.bin
Note: you can try later versions, but low RAM size on this device may cause trouble
Set the address of the tftp to 192.168.1.100 (static IP), start a terminal on the serial at 115200 8n1
power up the router and hit a key when prompted to interrupt CFE
now enter:
flashimage openwrt-96348GW-generic-squashfs-cfe.bin
to flash the device.
On reboot you can now configure your router through LuCi.
ToDo
There is a JTAG connector next to the serial - pinout unknown.
The device has a button marked “Secure Easy Setup” with a LED behind it. This is currently ignored
Lack of a FOSS driver prevents the ADSL from being used.

Opening the case
Serial
| | __ | | | <- Pin 1, GND | -- | | | <- Pin 2, Not Connected | -- | | | <- Pin 3, Router's Serial RX | -- | | | <- Pin 4, Router's Serial TX | -- | | | <- Pin 5, VCC | -- | | \__led__led__led__led____________________ Front of WAG54G
NOTE: You cannot plug directly those pins to your pc serial port. You need a RS232-TTL level adapter, see port.serial.
Configuration
The settings for the serial console are “38400 bauds, 8 bits, no parity, 1 stop bit (38400 8N1)”, with hardware and software flow control both disabled.
Interfaces
The default network configuration is:
| Interface Name | Description | Default configuration |
