How to use Linux Firmware with WN111v1 Wireless Adapter in Ubuntu 12.04

Asked by Julianloui

Today I was delighted to find a file named ar9710.fw in my Ubuntu 12.04 computer's /lib/firmware/ directory. It's supposed to be for the WN111v2 wireless adapter. Even though my adapter is a WN111v1, I still would like to learn how to use it just in case it might work.

Since I am totally new to Linux firmware, I'll appreciate receiving some advice or information on this matter. Even a simple example will be a great help to me. I am familiar with Ndiswrapper and think using Linux firmware may even be better.

When the driver module is loaded it may request a firmware file and look in /lib/firmware for the file. You won't "use" it manually. The driver will use it if needed.

How will this firmware file be used In my case? I am still totally in the dark in although the file is already in the /lib/firmware directory.

If I plug the adapter in now, what will happen next? Thanks.

Udev will detect the new device and start querying it. If the desired driver is available and udev requests it to be loaded it will be loaded into kernel space. If the loading of the driver requires a firmware file then the file name expected will be loaded from /lib/firmware

Can you help with this problem?
