Atheros Chipsets

This page was created to address the lack of easily obtainable information about Atheros chipsets

A list of Atheros' partners along with their products and chipsets can be found on the Atheros web site.

The list seems to be missing some of the very latest products but serves as a handy reference
for comparing products between manufacturers.
