The LinkSys WRT54G revisited (with openWRT)

Introduction

This section follows . This time we have three devices, all WRT54G, but different versions.


It appears that the third device (with the 'Atheros' CPU) cannot even be used with OpenWRT. We are going to use it to offer wireless connection to one of our home networks. The first two will be used to offer Linux installations to a remote site: one (nr. 2) at the site, the other will stay home as a sandbox.

The versions and their properties can be retrieved from the Wikipedia page on LinkSys WRT54G, or this forum page, which reduces the very concise information at linksysinfo.org to:
