Netgear WGT634U Console

It's pretty easy to attach a serial console to the router. There are two serial ports on the board, ttyS0 and ttyS1. The console is going to ttyS1 which conveniently also has the header soldered on.

Schematic

To communicate with the router use the following settings in minicom: 115200 8N1 , software flow control.

The serial console will display the boot messages and end with a logon prompt. You can login with "root" and "password". The newer versions of the routers automatically run a program called lrcfg which is a simple configuration tool.
