Linksys WAG54G

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device will end after 2019.
19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now.

The Linksys WAG54G is an ADSL gateway with wireless acccess point integrated.

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.
