Supported chipsets

  • AR6003: It is the third-generation Wi-Fi chip from Atheros optimized for the throughput, size, and energy efficiency needs of mobile and embedded devices. With its tiny footprint and energy-saving qualities, the AR6003 rounds out Atheros’ comprehensive Align® ecosystem of 1-stream 11n solutions, targeting smartphones, mobile gaming and portable CE devices.


  • Multi architecture support (64 bit)
  • Bi-endian support (big endian)
  • Upgrade CFG80211 support to work with the recent changes in the kernel.
  • AP Mode support using CFG80211.
  • WiFi Direct.


  • Known defects (To be updated)


We are in the process of upstreaming the driver.

This driver is upstream as part of the Linux 2.6.37 release under the staging area. It is also available for older kernels through the stable compat-wireless-2.6.37 releases. The goal is to eventually replace this driver with a proper mac80211 driver.
