The Linksys WAG54G is an ADSL gateway with wireless acccess point integrated.
This appears to be based on a Broadcom reference design, as all the chips were made by them.
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
[x] (x) (x) (x)
Gnd TxD 3.3V RxD
Attach a serial cable and an ethernet cable to the router, connect both to a PC/Linux box with a tftp server in.

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
to flash the device.
On reboot you can now configure your router through LuCi.
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.
This is essentially the same unit as the AG241v2, except for the wireless controller.
