Note to self:

When messing about with embedded systems such as WRT-54G, stick a note on the outside of the physical device indicating whether it is a DHCP client, DHCP server, or has a fixed IP address.

On this note, also indicate the means to manage the device, eg: SSH using keys only, specific key is X. Or simple username/password.

If using SSH keys for login to a device, make damned sure that key is backed up somewhere.

Make sure you snarf a mirror of the entire documentation for your software of choice, since the software may be dead, bought out, or just plain obsoleted by the time you come back to tinker with that device in two years time.  Or you might even need that device to get you connected to the Internet in order to read the online documentation.

Hope this helps someone else
