Go back –> Atheros Linux wireless drivers
ar9170usb is a GPL driver for the Atheros 802.11n USB chipset (AR9170).
See also otus, the driver which ar9170 is based on.
Before you can use the hardware, you have to get the the right firmware.
ar9170 will be part of the 2.6.31 kernel release but new updates (such as AVM Fritz support, and support for the one stage open source firmware) will be available until 2.6.32. You can however get the latest ar9170 driver, as targeted in the wireless-testing development tree by using git to get wireless-testing directly or by using the compat-wireless tarball which will get you only the wireless drivers.
Firmware is open! Go check the ar9170.fw page.
official device firmware
You have to pick the right one, download and put it into the right place. Normally this should be /lib/firmware. However some distributions put firmware in a different place.
two stage: recommended firmware
The firmware files are included in the firmware tree. The
retrieved the files through git.
